Hydrophobic molecule related to cholesterol. Many important hormones such as estrogen and testosterone are steroids.
A lipid found in plants and animals that share a common underlying chemical structure. They are usually hormones or constituents of cell membranes. Common steroids include estrogen, testosterone, cortisone, Vitamin D, and cholesterol.
any of several fat-soluble organic compounds having as a basis 17 carbon atoms in four rings; many have important physiological effects
any hormone affecting the development and growth of sex organs
a chemical compound with the same basic structure as the sex hormones and the adrenal cortical hormones, of which estrogen, testosterone, cortisone, and DCA are prime examples
a chemical substance derived from cholesterol
a drug derived from a hormone
a lipid characterized by a carbon skeleton with four fused rings and if it is herbal I dont think it will have this structure
an organic molecule with the multi-ring structure of cholesterol
a synthetically produced hormone, in this case it's testosterone
a type of (An oily organic compound insoluble in water but soluble
A type of medication that is a synthetic version of Cortisol or other hormones. When based on Cortisol, this type of medication suppresses the immune system and is therefore used to treat allergies, Asthma, EE, Autoimmune diseases, some forms of cancer, organ transplant rejection and other diseases, and to provide adrenal gland support in cases of adrenal insufficiency. If based on Estrogen, it is used as post-menopausal hormone replacement therapy.
Any of a group of organic compounds with a characteristic structure of four rings of carbon atoms, including many hormones, alkaloids, and vitamins.
hydrophobic, planar, multi-ring molecule which can be both a chemical messenger or hormone, or a structural unit of cells.
Any of a group of fat-soluble organic compounds including hormones, drugs, and other substances such as cholesterol.
Artificial growth hormone
A large class of pharmaceutical agents that chemically resemble cholesterol. Two better known types are anabolic steroids as used illegally in athletics, and glucocorticoid steroids which are used to reduce inflammation. This latter drug type is used in PRK to regulate regression and reduce post PRK inflammatory haze.
a class of chemicals formed from cholesterol or similar polycyclic molecules; includes hormones from the adrenal cortex, ovary and testis, sterols, vitamin D, bile acids and glycosides.
A family of organic, fat-soluble compounds. Many hormones, including the sex hormones, are classified as steroids.
A large group of chemical substances related in structure to one another and each containing the same chemical backbone. Many hormones, body constituents, and drugs are steroids. Examples: drugs used to relieve swelling and inflammation such as prednisone, dexamethasone, vitamin D, and the sex steroids such as testosterone.
A general class of chemical substances that are structurally related to one another and share the same chemical skeleton (a tetracyclic cyclopenta[a]phenanthrene skeleton). See the entire definition of Steroid
a natural occuring compound (fat-soluble and having a 17-cargon-atom ring as a basis), including many hormones and vitamin precursors.
A large family of chemical substances which includes hormones and drugs that have a chemical structure comprised of a few rings attached to each other. Most steroids contain twenty-seven or more carbon atoms.
Numerous natural or synthetic compounds that contain a 17-carbon 4-ring system and can modify reactions in the body
Member of a large family of structurally similar lipid substances. Steroid molecules have a basic skeleton consisting of four interconnected carbon rings. Different classes of steroids have different functions. All the natural sex hormones are steroids. Anabolic steroids increase muscle mass. Antiinflammatory steroids (or corticosteroids) can reduce swelling, pain, and other manifestations of inflammation.
any of the a large group of fat-soluble organic compounds, such as the sex hormones or bile acids, most of which have specific physiological action.
is a lipid characterized by a carbon skeleton with four fused rings. Different steroids vary in the functional groups attached to these rings. Hundreds of distinct steroids have been identified in plants and animals. Their most important role in most living systems is as hormones.
Gk, stereos,solid + eidos, form], any of a large number of hormonal substances with a similar basic chemical structure, produced mainly in the adrenal cortex and gonads
An organic fat-soluble compound.
A ring-shaped lipid structurally related to cholesterol.
A group of chemicals, many normally found in the body. Most steroids are hormones and affect body processes such as the overcoming of inflammation. Steroids medication decreases inflammation and inhibits immune reactions.
a group name for compounds that contain a specific chemical ring system; included are a group of hormones produced by the adrenal cortex and synthetically; they may be administered to reduce the symptoms of an allergic reaction.
a naturally occurring fat-soluble organic compound present in bile acids, many hormones, some natural drugs, and precursor of certain vitamins.
A class of lipids characterized by a four carbon ring structure. Male hormones(androgens) and female hormones(estrogens) are steroids as is cholesterol. Cholesterol is an important component in cell membranes, increasing the flexibility of the membrane.
hormone - any of numerous naturally occurring, fat-soluble organic compounds having a 17-carbon-atom ring as a basis. They include numerous hormones (sex steroids, adrenal corticosteroids, etc.) as well as certain natural drugs such digitalis or precursors of certain vitamins.
A natural or synthetic compound with a specific carbon structure. Steroids have many functions; however, their most important role is as hormones.
Any of a large number of hormonal substances with a similar basic chemical structure containing a 17-carbon 14-ring system and including the sterols and various hormones and glycosides.
A steroid is a terpenoid lipid characterized by a carbon skeleton with four fused rings. Different steroids vary in the functional groups attached to these rings. Hundreds of distinct steroids have been identified in plants, animals, and fungi.
