A mixture of lipoproteins found in blood, consisting of HDL (high-density lipoproteins), LDL (low-density lipoproteins), and VLDL (very-low-density lipoproteins). Present recommendations are to keep cholesterol levels below 200 mg/dl.
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 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.
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 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.
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 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.
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.
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.
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 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 white, fat-soluble substance found in animal fats and oils, in bile, blood, brain tissue,, nervous tissue, the liver, kidneys, and adrenal glands. It is important in metabolism and is a precursor of certain hormones.
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.
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.
(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 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 fatty substance produced by every cell in the body that is vital for health. It is a necessary component of all cell membranes. It is the precursor to all steroid hormone (including estrogen, testosterone, cortisol, and vitamin D). It is the leading organic molecule in the brain and is needed for brain function. Blood cholesterol carries antioxidant vitamins to the tissue. The majority of cholesterol in the blood is produced by the liver. Excess of cholesterol in the blood can contribute to heart disease.
a waxy, fat-like substance used by the body to build cell walls and make certain vitamins and hormones. The liver produces enough cholesterol for the body, but we also get cholesterol when we eat animal products. Eating too much cholesterol and saturated fat can cause the blood cholesterol to rise and collect along the inside walls of blood vessels. This is a risk factor for heart attack and stroke.
A fatlike material present in the blood and in most tissues. Elevated concentrations in the blood are associated with the decay of the walls of the arteries. Cholesterol is also a major component of gallstones.
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 speeds arteriosclerosis, or "hardening of the arteries."
A soft, waxy substance. The body makes enough cholesterol to meet its needs. 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. Blood cholesterol - Cholesterol circulating in the bloodstream. It is made in the liver and absorbed from the food you eat. The blood carries it for use by all parts of the body. A high level of blood cholesterol leads to atherosclerosis and an increased risk of heart disease. Dietary cholesterol - Cholesterol in the food you eat. It is present only in foods of animal origin, not those of plant origin. Dietary cholesterol, like dietary saturated fat, raises blood cholesterol, which increases the risk for heart disease.
A fat-like substance carried in the blood. A high level of cholesterol in the blood can lead to clogged arteries. Cholesterol is only present in foods from animals: mean, poultry, seafood, dairy products, eggs and animal fats like lard and butter.
an essential component of cell membranes and nerve fibre insulation, cholesterol is important for the metabolism and transport of fatty acids and the production of hormones and Vitamin D. Cholesterol is manufactured by the liver, and is also present in certain foods. High blood cholesterol levels have been linked to heart disease and may be a side effect of some anti-HIV medications.
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).
A soft, waxy substance found in the bloodstream and in all of your body's cells. 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 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. Cholesterol is carried in the blood stream by particles called lipoproteins. When total cholesterol is measured in the blood, it includes cholesterol carried by low-density lipoproteins (LDL) and high-density lipoproteins (HDL).
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.
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 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.
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."
An alcohol steroid found in animal fats. This fat-like substance is the primary cause for Atherosclerosis (narrowing of arteries). Normal cholesterol levels are recommended to be at levels less than 200 mg/dl.
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 bloodâ€” hypercholesterolemiaâ€”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.
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 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.
A soft, waxy substance found among the lipids (fats) in the blood. It is used to help form cell membranes and hormones and to perform other essential body functions. However, high cholesterol levels are a major risk factor for heart disease.
A fat like substance made by the body to construct cell membranes. Although the body makes cholesterol, ingestion of cholesterol from foodstuffs may cause gallstones as well as coronary artery disease.
Pronunciation: (kuh-LESS-tuh-rawl) A waxy, fat-like substance made in the liver, and found in the blood and in all cells of the body. 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.
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.
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 waxy, fat-like substance manufactured in the liver and found in all tissues, it facilitates the transport and absorption of fatty acids. In foods, only animal products contain cholesterol. An excess of cholesterol in the bloodstream can contribute to the development of atherosclerosis.
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.
A fat-like substance normally present in the bloodstream and needed for the development of 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 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 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 soft, waxy substance that is present in all parts of the body. It helps make cell membranes, some hormones, and vitamin D. The liver makes all the cholesterol a person's body needs, so eating too much from animal foods like meats and whole milk dairy products can make your cholesterol go up.
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 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 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 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
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.
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.
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 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 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 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 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.
A waxy, fat-like substance produced by the liver and contained in selected foods (e.g., egg yolks, coconut oil). Cholesterol is a form of lipid. The body produces all the cholesterol it needs to function normally. 200mg/dl or less is the desired blood level.
A fatty substance circulating in the blood and present in the tissues that is synthesized in the body and also comes from the diet. In excess amounts it may be deposited in arterial walls as athreosclerotic plaques. It circulates in two forms, HDL and LDL cholesterol.
1. biochemistry A pearly, fatlike steroid alcohol , C27H45OH, crystallizing in the form of leaflets or plates from dilute alcohol and found in animal fats and oils , in bile , blood , brain tissue , milk , yolk of egg , myelin sheaths of nerve fibres , the liver , kidneys and adrenal glands. 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 steroid alcohol found in a variety of foods which, if consumed in excessive amounts, is thought to contribute to the blocking of the arteries (arteriosclerosis) and can leave deposits in the skin in the form of yellow bumps.
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 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).
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.
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 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.
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 steroid-like substance present in some foods, notably animal fats, eggs, and dairy products. A high cholesterol level is associated with atherosclerosis, and may cause gallstones. However, some cholesterol in the body is necessary for healthy functioning.
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.
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.
Cholesterol is a waxy substance that is found naturally in humans. The body uses cholesterol in a number of ways, for example, to produce bile acids that help you digest fat. Cholesterol is important to health. However, too much cholesterol in the bloodstream can be unhealthy; it builds up in the artery wall and can lead to the signs and symptoms of coronary heart disease. Return to previous page.
a molecule found in all animal tissues. It is an essential molecule in the biosynthesis of steroid hormones. Blood levels of cholesterol are often elevated ( a risk factor for Coronary heart disease)in the presence of a high-fat diet.
A type of lipid (fat-like substance) that forms part of cell membranes and is used in a number of biochemical processes. Cholesterol is vitally important to the body, but an excess of certain types of cholesterol in the blood can lead to atherosclerosis.
(1) serum or blood cholesterol: a fat-soluble waxy substance (specifically the crystalline steroid alcohol 27H45OH) in the blood that is often deposited in artery walls. Cholesterol is used to produce bile acids and certain hormones and to construct cell membranes. Excess blood cholesterol is a result of a high-fat, high cholesterol diet or of genetic factors. (2) dietary cholesterol: a naturally occurring waxy substance ( 27H45OH, see above) found in animal fats and oils.
A type of fat used in your body to build cells and certain hormones. Cholesterol is also present in foods from animal sources such as whole milk, dairy products, meat, poultry, animal fats and egg yolks.
A chemical called a lipid that the body uses to make cell membranes and some hormones. HDL cholesterol, or high density lipoprotein, is â€œgoodâ€ cholesterol; LDL cholesterol, or low density lipoprotein, is â€œbadâ€ 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 â€œfat familyâ€.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 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.
A waxy, fat-like substance manufactured in the liver and found in all tissues. In foods, only animal products contain cholesterol. An elevated blood level of cholesterol constitutes an increased risk of developing coronary heart disease.
A soft, waxy substance found in all cells of the human body. Cholesterol is a type of lipid (fat) vital for the production of bile acids, hormones and vitamin D. Raised levels of cholesterol can lead to atherosclerosis.
A fat-like substance found in blood, muscle, liver, brain, and other tissues in people and animals. The body makes and needs some cholesterol. 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.
