a waxy substance that can be found in all parts of the body - it is made by the body and can be found in animal products such as egg yolk, dairy products, meat, poultry, fish, and shellfish.

a fatty substance in animal tissue that is an essential component of cell membranes and nerve fiber insulation. See also low-density lipoprotein.

a type of lipid, found only in animal foods.

A waxy, fat-like substance made by the bodies of humans and animals. It is found in meat, eggs and dairy products. A total cholesterol test measures several types of blood fats. One type is low-density lipoproteins that increase the plaque deposited inside the arteries and raises the risk of atherosclerosis. Another is high-density lipoproteins. These help carry fat away from artery walls. Triglycerides are a third type factored into a total cholesterol reading. The higher the triglycerides are, the greater the chances of developing atherosclerosis.

cholesterol: a soft, waxy substance found among the lipids (fats) in the bloodstream and in all of the body's cells. While cholesterol helps form cell membranes and other needed tissues, it cannot dissolve in blood, and a high blood cholesterol level is a major risk factor for coronary heart disease, which leads to heart attack.

a fatty substance normally produced by the body also found in animal foods and carried by the blood. May cause clogging of the blood vessels when levels are too high.

This is a type of lipid which, although most widely known as a "badfat" implicated in promoting heart disease and stroke, is a vital component in the production of manysteroid hormones in the body.

A fat-like substance in the body. The body makes and needs some cholesterol, which also comes from foods such as butter and egg yolks. Too much cholesterol may cause gallstones. It also may cause fat to build up in the arteries. This may cause a disease that slows or stops blood flow.

fat-like substance found in blood. Can build up on artery walls.

soft, waxy type of fatty particle (lipid) that circulates in the blood; building block for all cell membranes and many sex hormones

classified as a lipid, the most abundant steroid in animal tissues; located in cell membranes and used for synthesis of steroid hormones and bile salts

A fat-like substance that, if present in the blood in large amounts, is associated with the development of heart disease.

Is a type of fat known as the "bad fat". Exercising will help in eliminating the bad fat.

A white substance found in many foods that is an important element in cell walls in the body. An unusually high level of cholesterol in the blood is often a symptom of heart disease.

A precursor of all steroid hormones (androgens, estrogens, glucocorticoids).

A waxy substance that the body uses to synthesize steroid hormones (sex hormones, coristol, etc.). When present in excessive quantities in the blood, it increases the risk of heart disease. Cholesterol can be reduced through exercise and careful diet if thyroid hormone levels are normal.

A type of fat that, although most widely known as a "bad fat" implicated in promoting heart disease and stroke, is a vital component in the production of many hormones in the body. There are different types of cholesterol: namely, MDL and LDL (MDL being the "good" form and LDL being the "had" form).

A fatty substance in which carbon, hydrogen, and oxygen atoms are arranged in rings.

a fatty substance found in all human cells. It is transported in the blood attached to proteins. LDL cholesterol is the bad form as it forms the basis for atherosclerosis. HDL cholesterol is the good form as high levels of HDL can reduce the risk of atherosclerosis.

A fat-like steroid found in animal fats and oils and also produced by the body.

Cholesterol is a lipid. (a.k.a. fat) These lipids move through the bloodstream, where they attach to proteins, resulting in what is called lipoproteins (either HDL or LDL). When blood cholesterol levels are high, cholesterol and other fatty substances are more likely to build up in your blood vessels, restricting the flow of blood to and from the heart.

a constituent of saturated fat. The major component of the fatty deposits in atherosclerosis.

A waxy, odorless substance made by the liver that is an essential part of cell walls and nerves. Cholesterol plays an important role in body functions such as digestion and hormone production. In addition to being produced by the body, cholesterol comes from animal foods that we eat. Too much cholesterol in the blood causes an increase in particles called LDL(known as bad cholesterol) which increases the build-up of plaque in the artery walls and lead to atherosclerosis.

A waxy lipid, one member of the group of lipids known as sterols.

Chemical substance of the steroid type produced naturally in the body or ingested from certain foods. A minimum quantity of cholesterol is needed by the body, but an excess can cause various health problems, including cardiovascular disease and gallstones. Cholesterol in the diet has been linked to both benign prostate enlargement and to prostate cancer.

(C27H45OH) A fat soluble crystalline steroid alcohol, found in all animal tissues and fluids, especially in nervous tissues and bile.

A fatty substance produced predominantly by the liver, and necessary for building cell membranes, insulating the CNS, covering fats for blood transport, forming bile acids, oiling the skin and making steroid hormones. Blood cholesterols are not derived from food (digestion breaks them down) but are intentionally synthesized by the liver, in response to seeming need. Elevated cholesterols are the result of certain types of stress or metabolic imbalances, and the liver makes more than the tissues need. Although not a direct cause, high consumption of fats and proteins will convince the liver to kick into a fat/protein or anabolic stance...THEN it may oversecrete cholesterols, perhaps thinking you are putting food away for the winter.

A fatty substance found naturally in animal cells, including human cells. High levels of cholesterol in the blood are correlated with arteriosclerosis, the condition marked by deposits of fatty materials inside blood vessels leading to their narrowing or obstruction.

Waxy substance in human and animal tissue, excess deposits of which can narrow blood vessels, leading to heart disease.

There are two main types: low density lipoprotein (LDL) cholesterol and high density lipoprotein (HDL). HDL cholesterol carries cholesterol to the liver where it can be broken down and removed, thus helping to protect against heart disease.

A steroid alcohol which regulates certain cell functions and helps build cell membranes.

A crystalline substance, the most common animal sterol. Is a universal tissue constituent occurring most notably in bile, gallstones, the brain, blood cells, plasma, egg yolk and seeds. There are two types: high density lipoprotein and low density lipoprotein. High density lipoprotein is important for many physiological processes. Low density lipoprotein has been show to build up in arteries causing blockages which can lead to heart disease.

Category: Fat Cholesterol is a form of fat that the body needs for several functions (eg. the manufacture of hormones). Our bodies can produce all the cholesterol they need and do not require the additional cholesterol we eat in animal foods. People with a high level of blood cholesterol have an increased risk of developing a heart attack or stroke. The cause of this high level of blood cholesterol is due to an unbalanced diet (normally a diet high in saturated fat), and an unhealthy lifestyle (eg. smoking, sedentary disposition). LDL (Low density lipoprotein): the "bad" cholesterol, that encourages cholesterol buildup in the arteries, leading to heart attacks and strokes. HDL (High density lipoprotein): the "good" cholesterol, which is protective to our health by carrying the cholesterol out of the coronary arteries. Lipid Type Desirable Borderline High Risk High Risk Total Cholesterol 5.18 mmol/L 5.18 mmol/L to 6.20 mmol/L 6.21mmol/L HDL Cholesterol 1.55mmol/L - 1.04mmol/L LDL Cholesterol 3.36mmol/L 3.36mmol/L to 4.12mmol/L 4.13mmol/L Triglyceride1.69mmol/L 1.69mmol/L to 2.25mmol/L 2.26mmol/L

A sterol with a multi-ringed (steroid) structure. The amount of cholesterol per gram of butter is 2 mg.

This is a fatty substance which circulates in the blood stream. If your cholesterol level is too high it can cause the arteries to harden, which can lead to heart attacks and strokes.

A important component of blood lipids (fats) manufactured by the liver that's also the precursor of the steroid hormones, such as the sex and "fight or flight" hormones. Too much of some kinds, specifically low-density lipoprotein (LDL) and very-low-density lipoprotein (VLDL), if oxidized, can collect inside artery walls as plaque, restricting blood flow, reducing vessel flexibility and leading to heart disease. High-density lipoprotein (HDL) helps move LDL cholesterol out of the system. Vitamin E, lycopene and beta carotene protect LDL from oxidation; their antioxidant activity is enhanced in the presence of vitamin C. People concerned with cholesterol should watch their intake of foods containing saturated fats, which stimulate the liver to make more cholesterol. Dietary cholesterol from animal-based foods has little effect on blood cholesterol in healthy people.

Blood fats, that are present in most tissues.

Complex chemical present in all animal fats and widespread in the body and nerve fiber sheaths.

The most abundant steroid in animal tissues. Used as a vital part of the membrane in every cell in the body. Used a precursor to hormones. It is an animal sterol that is normally created by the liver. Without cholesterol we would die. It can be found in animal tissues and various foods

HDLs or high density lipoproteins are the "good" cholesterol. LDLs or low density lipoproteins are the "bad" cholesterol. It is all right to have high levels of HDLs, but a high concentration of LDLs is a health risk. Overall cholesterol levels should be under 200.

A steroid component of cell membranes and a substrate for the synthesis of steroid hormones and bile salts.

(ke-lès¹te-rôl´), fat-related compound found in the tissues and blood plasma of vertebrates. A STEROID, cholesterol is found in large concentrations in the brain, spinal cord, and liver, and is a necessary component of cell membranes. It can be obtained from animal products in the diet or synthesized in the liver. Cholesterol is the major precursor of the synthesis of vitamin D and the various steroid HORMONES and can crystallize in the GALL BLADDER to form gallstones. In the blood, cholesterol travels with a protein in an organic compound called a LIPOPROTEIN. Low-density lipoproteins (LDLs) convey cholesterol from the liver to the body's tissues, and high-density lipoproteins (HDLs) convey cholesterol out of the blood stream for excretion. High levels of LDLs in the blood, or low levels of HDLs, are associated with an increased risk of heart disease; in atherosclerosis (see ARTERIOSCLEROSIS) deposits of cholesterol (mainly LDL cholesterol) accumulate inside blood vessels. Reducing consumption of foods containing cholesterol and saturated fat has been found to lower blood cholesterol levels; cholesterol levels can also be reduced with drugs (e.g., lovastatin).1

A lipid molecule with a four-ringed steroid structure. Cholesterol is produced in the liver and is a necessary   component of cell membrane fluidity.

A lipid substance which is important in many essential body functions. It is found in foods of animal origin and is also manufactured in the body by the liver. Cholesterol levels in the blood increase with age. Blood levels above 200 Mg/dl are thought to contribute to accelerated atherogenesis (the formation of the plaque that blocks arteries) and for this reason, is considered to be a risk factor. Blood levels 180 mg/dl are most desirable.

Cholesterol is a waxy substance that is present in all animal cells. In the body, cholesterol is used to make estrogen and testosterone. Blood (or serum) cholesterol is the cholesterol that circulates in the bloodstream. It is a combination of the cholesterol obtained from food and the cholesterol that the body makes. Foods high in cholesterol include egg yolk, liver, and red meats. HDL-cholesterol and LDL-cholesterol are forms of lipoproteins. Lipoproteins help transport cholesterol throughout the body. HDL (high-density lipoprotein) is the "good" cholesterol and LDL (low-density lipoprotein) is the "bad" cholesterol. HDL participates in removing excess blood cholesterol from the body; LDL is the form that can build up in artery walls and thus is a serious risk factor for heart disease.

A fat lipid which has both good and bad implications within the human body. Good being known as HDL and bad being LDL. Bad cholesterol is associated with heart disease and stroke, whereas the body requires cholesterol for the production of many steroid

(pdf file) Cholesterol is a lipid (fatty substance) that is essential for life. It forms the membranes for cells in all organs and tissues in the body. A small amount of the body's cholesterol circulates in the blood in complex particles called lipoproteins. Measurement of blood cholesterol levels is used to estimate the risk of developing heart disease. HDL cholesterol HDL is a component of your total cholesterol. It is known as the "good" cholesterol because it removes excess cholesterol and LDL ("bad" cholesterol) from the arteries. The higher the HDL, the better. Low levels of HDL are associated with increased risk of heart disease. LDL cholesterol LDL is a type of lipoprotein that carries cholesterol in the blood. It is considered to be undesirable because it deposits excess cholesterol in walls of blood vessels and contributes to hardening of the arteries. LDL is known as the "bad" cholesterol. High LDL levels are associated with a higher risk for heart disease.

A soft, waxy substance found among the fats in the bloodstream and in all the body's cells. It is a constituent of all animal fats and oils. Cholesterol is an important part of a healthy body since it is used to form cell membranes, some hormones, and other needed tissues. A high level of cholesterol in the blood, however, is a major risk factor for heart disease.

Cholesterol is a fatty substance (a lipid) that is an important part of the outer lining (membrane) of cells in the body of animals. Cholesterol is also found in the blood circulation of humans. The cholesterol in a person's blood originates from two major sources, dietary intake and liver production. Dietary cholesterol comes mainly from meat, poultry, fish, and dairy products. Organ meats, such as liver, are especially high in cholesterol content, while foods of plant origin contain no cholesterol. After a meal, cholesterol is absorbed by the intestines into the blood circulation and is then packaged inside a protein coat.

A fatlike substance that is a building block of the outer layer of cells (cell membranes). It is essential to the formation of bile acids, cell membranes, vitamin D and certain hormones. Cholesterol is not dissolved in the blood, but is transported in the bloodstream as water-soluble molecules known as lipoproteins. The lipoproteins are characterized by their density: high density lipoprotein (HDL) and low density lipoprotein (LDL).

It's an important part of a healthy body because it is used to form cell membranes, certain hormones, vitamin D, and needed tissues. Cholesterol is also involved in producing bile acids, which help the body process the fats you eat. Cholesterol comes from two sources: your body and your diet. Your body manufactures some cholesterol, and the rest comes from the animal products that you eat, such as meats, eggs, butter, cheese and whole milk.

Substance made from the fat that we eat. If we make too much of it, it can block our tubes in our bodies, for example the tubes in our heart called arteries. This means the heart cannot pump the blood around our body very easily, which can then sometimes cause a heart attack in adults.

a type of fat present in the blood that is the prime cause of atherosclerosis. See background information on cholesterol.

A waxy, fat-like substance used by the body to build cell walls. It is either produced in the liver or absorbed from the animal fats we eat.

A waxy substance made by the body and found in meats, eggs, and other foods. Your body needs some of it, but too much is bad for you.

Cholesterol is a special kind of fat which is found in the bloodstream and all cells of the body. The body produces its own cholesterol in the liver. Apart from that, it is ingested through animal products such as meat, fish, eggs, and dairy products. Though a certain amount of cholesterol is necessary to form, e.g. cell membranes, some hormones, and tissues; high cholesterol levels are a major risk factor for coronary heart diseases (CHD).

A fatty substance that higher organisms use in the construction of cell membranes and as an ingredient for making steroid molecules; it is carried through the bloodstream in molecules called lipoproteins

A sterol present in all animal tissues. Free cholesterol is a component of cell membranes and serves as a precursor for steroid hormones, including estrogen, testosterone, aldosterone, and bile acids. Humans are able to synthesize sufficient cholesterol to meet biologic requirements, and there is no evidence for a dietary requirement for cholesterol. Dietary cholesterol—Consumed from foods of animal origin, including meat, fish, poultry, eggs, and dairy products. Plant foods, such as grains, fruits and vegetables, and oils from these sources contain no dietary cholesterol. Serum cholesterol—Travels in the blood in distinct particles containing both lipids and proteins. Three major classes of lipoproteins are found in the serum of a fasting individual: low-density lipoprotein (LDL), high-density lipoprotein (HDL), and very-low-density lipoprotein (VLDL). Another lipoprotein class, intermediate-density lipoprotein (IDL), resides between VLDL and LDL; in clinical practice, IDL is included in the LDL measurement.

high blood cholesterol is one of the four major risk factors for coronary heart disease (cigarette smoking, high blood pressure and a sedentary lifestyle are the other three)

A fatty substance that is found in the body and in foods of animal origin. It is produced by the liver and is needed for the manufacture of hormones and enzymes for normal body processes. Too much cholesterol in the blood leads to heart and blood vessel diseases.

A fatlike substance that circulates in the blood and helps build cell membranes; high levels increase the risk of heart attack.

A fat-soluble waxy substance made by the liver or obtained from dietary sources, that circulates in the bloodstream in association with protein lipoproteins. Low-density lipoproteins (LDL), also called "bad cholesterol," cause plaque buildup on the artery walls, while high-density lipoproteins (HDL) or "good cholesterol" clean the arteries of plaque. A favorable cholesterol profile of more HDL and less LDL is the result of healthy diet and proper exercise.

A type of fat produced by animals and humans. Dietary cholesterol refers to the content or amount of cholesterol contained in a food source. High levels of cholesterol in the blood stream have been linked to increased heart disease. Recommended consumption of cholesterol is less than 300 mg a day. Normal cholesterol values in the blood are less than 200 mg.

One of the body's circulating fat substances.

Cholesterol is a natural chemical «construction block» the body uses to produce hormones, biliary acid (which helps digestion), cell membranes and other tissues. Without cholesterol, our body could not function. However, too much cholesterol can cause problems, the most important being atherosclerosis. Two types of cholesterol are commonly mentioned: -Food cholesterol: cholesterol from other animals, absorbed from food such as eggs, cheese and meat. -Total cholesterol / blood cholesterol: cholesterol contained in your blood. It is transported through the bloodstream within lipoproteins Back

A fat-like substance normally found in blood and body tissues. A high level cholesterol in the blood has been shown to be a major factor for developing heart disease. Dietary cholesterol in found in all animal products, but is especially high in egg yolks and organ meats. Eating foods high in dietary cholesterol and saturated fat tends to raise the level of blood cholesterol. Foods of plant origin such as fruits, vegetables, grains, and legumes contain no cholesterol. Cholesterol is found in foods from the milk, meat, and fat exchange lists. (also see lipid)

A substance the body uses to make cell walls and certain vitamins and hormones. The liver produces enough cholesterol for these purposes, and in most people keeps the blood cholesterol level below 200 milligrams per deciliter (mg/dl). But blood cholesterol rises with consumption of animal products, which contain both cholesterol and saturated fat. The atherosclerotic plaques that lead to heart attack and stroke are rich in cholesterol.

A soft, waxy substance manufactured by the body and used in the production of hormones, bile acid, and vitamin D and present in all parts of the body, including the nervous system, muscle, skin, liver, intestines, and heart. Blood cholesterol circulates in the bloodstream. Dietary cholesterol is found in foods of animal origin.

This is a type of fat (lipid) essential for the human body. It is pearly colored, waxy, and soapy to the touch. Generally, there are two main classes of lipoproteins (lipid-protein combination) high-density lipid (HDL), the " good cholesterol," and low-density lipid (LDL), the " bad cholesterol."

Cholesterol is a soft, waxy substance found among the lipids (fats) in the bloodstream and in all your body's cells. It is used to form cell membranes, some hormones and other needed tissues. But a high level of cholesterol in the blood— hypercholesterolemia—is a major risk factor for coronary heart disease.

A white tasteless fat-like substance found in animal fats, oils, bile, brain tissues, milk, egg yolk, nerve myelin, liver, kidneys and adrenals. Mostly synthesised in the liver and normally present in the blood, cholesterol plays an important role in many bodily functions such as producing steroid hormones, insulating nerve fibres and forming bile acids. A high level of blood cholesterol is one of the risk factors for heart disease.

Classified as a sterol and is an important fat-soluble compound in animal cells (therefore, animal fats), but only found in trace amounts in plants (therefore, vegetable oils).

A crystalline substance that is soluble in fats that, in excess, can be a potential threat to health.

Cholesterol is a waxy, fat-like substance that is found in your bloodstream and in all your body's cells. Your body needs cholesterol to work properly. However, a high level of cholesterol in your blood can cause fatty deposits to build up in your arteries and block normal blood flow. If your arteries are blocked you could have a heart attack (blocked arteries to the heart) or stroke (blocked arteries to the brain). Most of the cholesterol in your blood is made in your liver. The rest of your blood cholesterol is affected by other factors, such as the type of food that you eat. For example, the amount of cholesterol in your blood is influenced by the total amount of fat and the kind of fat in your diet.

A compound belonging to a family of substances called sterols, which combine with fats and circulate in the bloodstream.

HDL or good cholesterol carries cholesterol away from the arteries, helping to remove it from the body. LDL or bad cholesterol can build up in the arteries and lead to serious diseases.

Fatty substance normally present in blood. See Chapter 6.

A complex fatty molecule made by the liver and transported to the body in the circulating blood. Cholesterol is a 4 ring organic compound which is part of the normal cell wall of most mammalian cells. Excess cholesterol occurs in patients who either produce too much or fail to metabolize cholesterol. The walls of some arteries absorb circulating cholesterol and other fats from the blood and slowly form a reaction called atheromatous plaque. As this builds up, the artery can be progressively blocked.

Cholesterol is important for good health and is needed for making cell walls, tissues, hormones, vitamin D, and bile acid. Cholesterol also comes from eating foods taken from animals such as egg yolks, meat, and whole-milk dairy products.

Lipid Species

A fatty substance known as a sterol that is a major component of cell membranes, especially the main (plasma) membrane. It is also required for digestive bile acids and sterol hormones. Some cholesterol is taken in from certain foods but most is produced by the cells of the body, notably the liver. A constant supply of cholesterol is needed for cell growth and maintenance and is distributed in the blood stream by LDL.

A fat-like substance that can deposit on the artery wall, narrowing or blocking blood flow.

A type of fat found in most body tissues.

an important component of body cells, cholesterol is involved in the formation of hormones and bile salts, as will as the transport of fats in the bloodstream.

Membrane Synovial

An important steroid that is the precursor for the body to make sex hormones, adrenal hormones, and other molecules. A component of all animal fats and oils. It is found in the blood in three forms: (1) High Density Lipo-protein (HDL), which protects against plaque formation in the arteries( atheroschlerosis); (2) Low Density Lipo-protein (LDL) which promotes plaque formation (atheroschlerosis); and (3) Very Low Density Lipoprotein (VLDL), also a plaque promoter.

A chemical compound manufactured in the body. It is used to build cell membranes and brain and nerve tissues. Cholesterol also helps the body make steroid hormones and bile acids.

a fatty substance that occurs naturally in the body and is necessary for hormone production, cell metabolism and other vital processes. High levels of blood cholesterol are a contributing factor to coronary heart disease. There are two types of cholesterol, low density lipoproteins (LDL) and high density lipoproteins (HDL). LDL, which is sometimes called "bad cholesterol" can adhere to the walls of the coronary arteries. This process is called atherosclerosis. HDL cholesterol, sometimes called "good cholesterol" can act as a protective guard by removing LDL's from the walls of blood vessels.

an animal sterol occurring in plasma membranes.

This is a fat that is made naturally in the body. The body needs some cholesterol, but too much from dietary sources can cause CHD (coronary heart disease).

Although it is a necessary substance, if levels of cholesterol are too high, it can be deposited on artery walls, eventually narrowing or blocking blood flow. There are two types of cholesterol, know as "bad cholesterol" (LDL) and "good cholesterol" (HDL).

A lipid (fat) that is an important constituent of body cells and essential in the production of sex hormones and the repair of cell membranes. Cholesterol is transported in the blood in two main forms, high-density lipoproteins (HDL) and low-, or very-low density lipoproteins (LDL, VLDL). An imbalance in the quantities of these lipoproteins creates a risk factor for coronary heart disease. A preponderance of LDL and/or VLDL is considered a risk factor.

a substance normally made by the body, but also found in foods from animal sources, like beef, eggs, and butter. Too much cholesterol in the body can lead to narrowing and blockage of the arteries, especially those that feed the heart and keep it healthy. High cholesterol can also cause the formation of gallstones. Ideally, blood cholesterol levels should be less than 200mg/dL.

Cholesterol, a primary component of cell membranes, enables the body to process vitamin D, steroid hormones, and bile acids. In addition to the cholesterol produced by the liver and several other organs, human beings ingest substantial amounts of cholesterol in the course of a normal diet. Cholesterol is not soluble in the blood; therefore, in order to circulate in the bloodstream, cholesterol must be attached to certain proteins called lipoproteins. Low-Density Lipoproteins (LDLs) transport cholesterol from the liver, where it is produced, to the cells where it is separated from the lipoprotein for use. It is chiefly the cholesterol associated with LDLs that builds up as fatty deposits in the arteries. Conversely, High-Density Lipoproteins (HDLs) may possibly transport excess cholesterol from the tissues back to the liver, where it is broken down into bile acids and eliminated from the body. HDLs may actually serve to retard or reduce fatty buildup.

Substance manufactured by the liver and other organs and consumed via animal fat. High-fat diets increase the amount made. It is believed that high levels lead to collection of cholesterol in the arteries, possibly leading to serious health risks.

Only foods of animal origin such as meat, fish, poultry, eggs, cheese and milk contain cholesterol. Plant foods do not contain cholesterol. Although some cholesterol is obtained from these foods, most cholesterol is produced in the liver and other organs. Dieting, weight loss and exercise will reduce elevated cholesterol levels.

a substance in animal tissue that is an essential component of cell membranes and nerve fiber insulation. Cholesterol is important for the metabolism and transport of fatty acids and in the production of hormones and Vitamin D. Cholesterol is manufactured by the liver, and is also present in certain foods (e.g., eggs, shellfish). There are 2 types of cholesterol in the blood, high-density (HDL) and low-density (LDL) lipoproteins. Very low cholesterol levels may indicate malnutrition.

a steroid alcohol present in animal cells and body fluids, important in physiological processes, and implicated experimentally as a factor in atherosclerosis.

a soft, waxy substance manufactured by the body and used in the production of hormones, bile acid, and vitamin D. It is present in all parts of the body, including the nervous system, muscle, skin, liver, intestines, and heart. Cholesterol regulates membrane fluidity, functions as a precursor molecule in various metabolic pathways and as a constituent of low-density lipoproteins may cause arteriosclerosis

A fat-like substance that is produced by the liver and found in all food from animal sources; an essential component of body cells and a precursor of bile acids and certain hormones.

one of the fat levels in the blood stream - a high cholesterol value is a risk for getting heart diseases or strokes. Diet and drugs can reduce levels of cholesterol.

A waxy fat your body uses to make cell membranes, the sheaths that cover your nerves, and hormones, among other things.

Cholesterol is one of several types of fats that play an important role in our body.

The most common type of steroid in the body, cholesterol has gotten something of a bad name. However, cholesterol is a critically important molecule. See the entire definition of Cholesterol

A waxy, fat-like substance found in every body cell. What you eat can raise or lower blood cholesterol level. Eating high-saturated fat, high cholesterol foods like fatty meats, fried foods, cookies, cakes and eggs contributes to high blood cholesterol. Elevated total cholesterol is a risk factor for coronary heart disease.

A waxy substance found only in food that comes from animals. See larger view

A waxy substance produced by the body and taken in with food. The body needs cholesterol for functions such as making hormones. When too much cholesterol circulates in the blood, it leads to atherosclerosis and an increased risk of heart disease. Blood cholesterol refers to the cholesterol circulating in the bloodstream; dietary cholesterol is the cholesterol consumed in food. (Read about " Cholesterol")

a fat-like substance found in foods of animal origin, such as egg yolks and liver. The human body also manufactures it. Too much cholesterol may narrow or block heart and blood vessels.

A fatty substance that occurs naturally in the blood, cell walls, and most body tissues. Cholesterol is made by the liver, and also enters the body via foods rich in saturated fat. Excess cholesterol collects in fatty deposits called plaques along artery walls, a major feature of coronary artery disease.

Cholesterol is not a fat, but rather a fat-like substance classified as a lipid. Cholesterol is vital to life and is found in all cell membranes. It is necessary for the production of bile acids and steroid hormones. Dietary cholesterol is found only in animal foods. Abundant in organ meats and egg yolks, cholesterol is also contained in meats and poultry. Vegetable oils and shortenings are cholesterol-free.

High blood cholesterol is a risk factor in the development of coronary heart disease. Most of the cholesterol that is found in the blood is manufactured by the body, in the liver, at a rate of about 800 to 1,500 milligrams a day. By comparison, the average American consumes 300 to 450 milligrams daily in foods.

Blood cholesterol is divided into three separate classes of lipoproteins: very-low density lipoprotein (VLDL); low-density lipoprotein (LDL), which contains most of the cholesterol found in the blood; and high-density lipoprotein (HDL). LDL seems to be the culprit in coronary heart disease and is popularly known as the "bad cholesterol." By contrast, HDL is increasingly considered desirable and known as the "good cholesterol."

A soft, fat-like substance found naturally in the body.

A soft waxy member of the lipid (fats) family Important in cell membrane formation Used to form hormones, vitamin D Made from breakdown products of all the major food groups: carbohydrates, fats and proteins Found in animal food sources

The body uses cholesterol to digest dietary fats, make hormones, build cell walls, and assist in other important processes.

A steroid alcohol found in animal fats. This fat-like substance is implicated in the narrowing of the arteries in atherosclerosis.

Fat like substance essential to human and animal life. It builds and repairs cells and is found large quantities in brain and nerve tissue. The liver produces all the cholesterol the body needs.

A fat-like substance made by the bodies of people and animals. In correct amounts, cholesterol has important jobs in the body. But when the level of cholesterol in the bloodstream becomes too high, it can build up on blood vessel walls. Having a blood cholesterol level greater than 200 mg/dL increases a person's risk for heart disease.

a steroid produced by the human body, which acts as the precursor for all steroid hormones.Too much cholesterol, however, may cause fat to build up in the artery walls and cause a disease that slows or stops the flow of blood

Cholesterol is a natural waxy substance needed by your body to work properly and is needed to produce hormones, and helps digest food. Cholesterol is always transported in your blood by a carrier called a lipoprotein, and there are high density lipoproteins (HDL) and low density lipoproteins (LDL). Your risk of developing cardiovascular disease is lower if you have a low level of LDL cholesterol and a high level of HDL cholesterol. Blood cholesterol is produced in the body. About 20 percent of blood cholesterol is affected by the food that you eat, and the rest is manufactured in the liver. Smoking, lack of physical activity, excess body weight, stress and family history also have an effect on blood cholesterol levels.

Membrane Scrotum

A waxy, fat-like substance that occurs naturally in all parts of the body and is found in many types of food.

A type of fat, which, depending on the type, can be good or bad for the body. "Good" cholesterol is involved in the formation of many important hormones, while "bad" cholesterol can contribute to stroke and heart disease.

The most abundant fatty substance in animal tissues. High levels in the diet are a factor in the cause of atherosclerosis.

A soft fat-like substance that, in moderate amounts, is essential for healthy cell membranes. Excess amount of "bad" cholesterol (low-density lipoprotein, or LDL) can combine with other substances in the body to produce a plaque-like substance that can clog the arteries. "Good" cholesterol (high-density lipoprotein, or HDL) can help reduce bad-cholesterol levels.

fat substance found in animal meats, dairy products and produced by the liver; a high level of cholesterol in the blood is a risk factor for developing heart disease Blood cholesterol can be elevated by cyclosporine

A substance found in the fat, tissues, and blood of animals and humans. Too much cholesterol in a person's blood can cause heart disease

a white, fatty matter manufactured by the body; essential for cells, hormone production and other functions; only found in animals and their by products. High levels lead to plaque formations and to coronary heart disease

A fat like substance that is an essential component of human cells. Too much cholesterol in the blood will stick to artery walls, clog them, and lead to atherosclerosis.

A fatty substance made by the liver from fats and carbohydrates. Your body uses cholesterol to help form cell membranes, hormones, and vitamin D. The liver makes all of the cholesterol needed for your body. Additional cholesterol enters your bloodstream through the foods that you eat. Cholesterol cannot be dissolved in the blood and must be transported to and from cells by special carrier proteins called lipoproteins. The two most important types of lipoproteins are low-density lipoproteins (referred to as LDL, which forms "bad cholesterol") and high-density lipoproteins (called HDL, which forms "good cholesterol").

A white crystalline substance (C27H45OH) found in animal tissues and various foods that is normally synthesized by the liver. Its level in the bloodstream can influence the development of certain conditions, such as coronary artery disease. Reference: L1

a fatty substance that can accumulate in arteries and block them when present in high levels in the blood

A type of lipid (fatty substance) that builds inside tissues; The body produces cholesterol, or it is obtained form eating animal products. The total cholesterol is not as important as the ratio of low-density lipoproteins, LDLs to high-density lipoproteins, HDLs. The recommended ratio is below 5 to 1. Cholesterol accumulation in the arteries due to excess saturated fats in the diet and lack of exercise leads to atherosclerosis.

Cholesterol (CHOH) is a white crystalline substance, found in animal tissues and various foods, that is normally synthesized by the liver and is important as a constituent of cell membranes and a precursor to steroid hormones. Its level in the bloodstream can influence the pathogenesis of certain conditions, such as the development of atherosclerotic plaque and coronary artery disease (from American Heritage Dictionary). Cholesterol is a blood fat needed by the body in moderate amounts. However, high cholesterol levels can lead to atherosclerosis and coronary artery disease (CAD) (from http://heart.healthcentersonline.com/cholesterol/).

a substance that circulates in the blood and plays a role in the formation of blockages. Cholesterol originates in foods that are rich in animal fats.

A waxy substance that circulates in the bloodstream. When the level of cholesterol in the blood is too high, some of the cholesterol is deposited in the walls of the blood vessels. Over time, these deposits can build up until they narrow the blood vessels, causing atherosclerosis, which reduces the blood flow. The higher the blood cholesterol level, the greater is the risk of getting heart disease. Blood cholesterol levels of less than 200 mg/dL are considered desirable. Levels of 240 mg/dL or above are considered high and require further testing and possible intervention. Levels of 200-239 mg/dL are considered borderline. Lowering blood cholesterol reduces the risk of heart disease.

Membrane Spectrum

It constitutes a large part of the most frequently occurring type of gallstones and occurs in atheroma of the arteries , in various cysts and in carcinomatous tissue . Most of the bodys cholesterol is synthesised in the liver , but some is absorbed from the diet . It is a precursor of bile acids and is important in the synthesis of steroid hormones .

A lipid which higher organisms use in the construction of cell membranes and as a precursor molecule in steroid synthesis. If a person produces too much cholesterol, the excess often gets laid down on the interior of blood vessels as plaque, causing heart disease, hardening of the arteries, and often heart attacks or strokes.

A fatty substance (lipid) essential for the digestion of fat and the formation of estrogen and testosterone, digestive juices and Vitamin D.

A waxy lipid produced by animal cells that is a prominent component of cell membranes.

Lipid Serum

fatty substances that circulate in the bloodstream. Estrogen, progesterone and testosterone are made from cholesterol. Too much cholesterol is associated with heart disease.

A substance similar to fat that is found in the blood, muscles, liver, brain, and other body tissues. The body produces and needs some cholesterol. However, too much cholesterol can make fats stick to the walls of the arteries and cause a disease that decreases or stops circulation.

a substance both made by the body and consumed in food. Two types are known: low-density lipoproteins (LDL) and high-density lipoproteins (HDL). HDL is often called the 'good' cholesterol and LDL is called the 'bad' cholesterol. This is because HDL helps transport cholesterol in the body to the liver, where the body then prepares to excrete it. LDL actually transports cholesterol from the liver to cells in the body. Once the body's cells have all of the cholesterol they need, the extra cholesterol brought by the LDL can build up along blood vessel walls as plaque. People with high total cholesterol as compared to their HDL cholesterol are at increased risk for heart disease. Cholesterol is used in the manufacture of hormones, bile acid, and vitamin D. It is present in all parts of the body, including the nervous system, muscle, skin, liver, intestines, and heart.

A fat-like substance found in blood, muscle, liver, brain, and other tissues of body that results from either dietary intake or synthesis of body.

a waxy substance, produced naturally by the liver and also found in foods, that circulates in the blood and helps maintain tissues and cell membranes. Excess cholesterol in the body can contribute to atherosclerosis and high blood pressure.

Type of lipid which is a vital component in the production of many steroid hormones in the body. It also plays a vital role in proper cell membrane structure and functioning. There are two types of cholesterol: HDL (good) and LDL (bad).

A type of lipid used by the body to make cell membranes, bile, and steroid hormones.

animal sterol that is present in all tissues of the human body but highly concentrated in the blood, bile, gallstones, and the brain.

An essential fat in the body when in excess causes atherosclerosis

Cholesterol is a fat (lipid) measured to assess the risk for atherosclerosis (fat accumulation in the walls of arteries).

A type of fat that circulates in your blood. It comes from two sources. the body makes its own regardless of what is eaten and from foods containing animal products.

A fatty solid found throughout the body, including the bile, where it may solidify to form gallstones; cholesterol stones account for more than 85% of all gallstones.

a fatty substance or sterol used by the body for production of hormones and the formation and maintenance of myelin. High levels in the blood stream are a marker for heart disease.

A fatty material found only in foods of animal origin; buildup in coronary arteries leads to coronary artery disease; cholesterol increases when saturated fat is eaten.

A fat-like sterol used by the body for production of hormones (including testosterone), vitamin D, and cell membranes; high levels in the blood stream are a marker for heart disease.

Cholesterol is a compound composed of carbon, hydrogen and oxygen atoms arranged in rings. It is found only in animal foods such as meat, eggs and dairy products, as well as shellfish. In the body, dietary cholesterol serves as a structural component of cell membranes and also contributes to other functions.

a lipid used in the construction of cell membranes and as a precursor in the synthesis of steroid hormones. Dietary cholesterol is obtained from animal sources, but cholesterol is also synthesized by the liver. Cholesterol is carried in the blood by lipoproteins (e.g., LDL and HDL). In atherosclerosis, cholesterol accumulates in plaques on the walls of some arteries.

A soft, waxy substance found among the fats in the bloodstream and in all the body's cells. Cholesterol can undergo various pathways that result in the synthesis of various steroids. It is also an important determinant of membrane fluidity, and an improper amount in the body can lead to membrane instability, which leads to cell death.

A fat-like substance found in animal tissue and present only in foods from animal sources such as whole milk products, meat, fish, poultry, animal fats and egg yolks.

Although this fat-like substance is generally regarded as "bad," and implicated in promoting heart disease and stroke, cholesterol is a requisite for the production of most hormones in the body. It is further vital for regulating cellular structure and function. The main types of cholesterol include HDL and LDL (HDL being the "good" form and LDL being the "bad" form). Cholesterol can be produced by the liver as well as obtained through the diet.

A form of fat that performs necessary functions in the body but can also cause heart disease; cholesterol is found in most foods.

A fat-like steroid alcohol, responsible for many metabolic processes related to structure and function of mammalian cells.

A fat-like substance needed for the development body cells. Cholesterol is both produced by the body and found in animal foods. Although it is a necessary substance, if levels of cholesterol are too high it can be deposited on the artery wall, narrowing or blocking blood flow and leading to coronary heart disease.

A type of fat normally present in the bloodstream. A high level appears to be directly related to the risk of developing heart disease.

This is a substance both made by the body and consumed in food products that come from animals. Primarily, it travels in the blood as two compounds: low-density lipoproteins (LDL) and high-density lipoproteins (HDL). In practice, HDL is often called the 'good' cholesterol and LDL is called the 'bad' cholesterol. The reason for this is that HDLs help transport cholesterol in the body to the liver, where the body then prepares to excrete it. LDLs, on the other hand, actually transport cholesterol from the liver to cells in the body. Once the body's cells have all of the cholesterol they need, the extra cholesterol can build up along blood vessel walls as plaque. People with high total cholesterol to HDL cholesterol ratios are at increased risk for heart disease because in general, they are transporting more cholesterol to cells than they need.

one of the major types of fats made by the body. It is an important component of body cells and is a building block for the formation of hormones and bile salts. Some cholesterol is secreted into bile, and many persons develop cholesterol gallstones in their gallbladders.

A fat-like material that is eaten as part of meat and other animal products, and is also made by the human body. Cholesterol has several beneficial uses in the body, but it can also be harmful when it builds up in the walls of arteries and causes them to narrow.

A white, fatty crystalline alcohol; tasteless and odorless; found in sebaceous material, skin, and other animal tissues, especially nerve tissue.

is a waxy substance produced by the body and found in foods that come from animals. The body will make all the cholesterol it needs. Cholesterol from foods is only a burden to the body.

Cholesterol is a soft, fat-like, waxy substance found in the bloodstream and in all your body's cells. It's normal to have cholesterol. Cholesterol is made by the liver and also supplied in the diet through animal products such as meats, poultry, fish and dairy products. It's an important part of a healthy body because it's used for producing cell membranes and some hormones, insulating nerves and serves other needed bodily functions. But too much cholesterol in the blood is a major risk for coronary heart disease, which leads to heart attack.

A lipoid manufactured by the liver. It is more commonly located in the skin, fatty tissues, and brain tissue. It forms a protective cream with sebum and water to lubricate and protect the skin.

A chemical called a lipid that the body uses to make cell membranes and some hormones. HDL cholesterol, or high density lipoprotein, is “good” cholesterol; LDL cholesterol, or low density lipoprotein, is “bad” cholesterol.

A soft, waxy substance that is found in most parts of the body, including muscles, skin, the liver, intestines, and heart. A high level of cholesterol in the blood can lead to hardening of the arteries (atherosclerosis) and an increased risk of heart disease.

(ko-LES-te-rol) A fat-like substance that is made by the body and is found naturally in animal foods such as meat, fish, poultry, eggs, and dairy products. Foods high in cholesterol include liver and organ meats, egg yolks, and dairy fats. Cholesterol is carried in the blood. When cholesterol levels are too high, some of the cholesterol is deposited on the walls of the blood vessels. Over time, the deposits can build up causing the blood vessels to narrow and blood flow to decrease. The cholesterol in food, like saturated fat, tends to raise blood cholesterol, which increases the risk for heart disease. Total blood cholesterol levels above 240 mg/dl are considered high. Levels between 200-239 mg/dl are considered borderline high. Levels under 200 mg/dl are considered desirable.

A substance belonging to the “fat family”.It is essential for the organism, as it is necessary for the production of bile acids and some types of hormones, including male and female sex hormones. Cell membranes are also partly made of cholesterol. It originates from two sources:a) endogenous production by the liver, b) exogenous introduction through food consumption.Blood carries cholesterol to the tissues through the proteins known as lipoproteins.Problems arise not from the presence of cholesterol but from its excess, which is a major risk factor for cardiovascular diseases.

A lipid transported in the blood in high and low density lipoproteins (HDL and LDL). High HDL levels are somewhat protective against coronary heart disease.

a component of animal fats and oils that is found in the diet (eg, egg yolks) and synthesised in the body Chronic disease: a continuing disease process with progressive deterioration.

A substance found in animal-based foods and manufactured by the liver. It is an essential building block for healthy nerves, cells, and the production of some hormones, but high levels carry the risk of atherosclerosis.

The body's most common type of steroid, it is crucial to the formation of Vitamin D, sex hormones (progesterone, estrogens and androgens), mineralocorticoid hormones (aldosterone) and glucocorticoid hormones (cortisol) and bile acids (for digestion of fat). It is carried in the blood stream as lipoproteins, e.g. LDL (low density lipoproteins) and HDL (high density lipoproteins). Cholesterol is also essential for cell membrane function.

Fat related compound that occurs naturally and plays a vital role in metabolism. However, high cholesterol is a risk factor in coronary artery disease. It results in fatty deposits on arterial walls and an increased blood pressure. The recommended daily intake of dietary cholesterol is less than 200 - 300 mg. per day.

A fat-like substance that is found in certain foods and is also made in the body. Cholesterol travels through the bloodstream as low-density lipoproteins (LDL, or "bad" cholesterol) and high-density lipoproteins (HDL, or "good" cholesterol). LDL delivers cholesterol to the body cells, while HDL takes cholesterol out of the bloodstream. Too much cholesterol may cause fat build up in the artery walls and lead to arteriosclerosis, a disease that slows or stops the flow of blood. Egg yolks and butter contain a lot of cholesterol.

A fat-soluble substance present in the blood and in animal fats that facilitates absorption and transport of fatty acids, and is necessary in hormone production. High levels of blood cholesterol have been linked to atherosclerosis and heart disease. See high and low density lipoprotein cholesterols.
