A group name for lipids that contain a hydrogenated cyclopentanoperhydrophenanthrene ring system. Some of the substances included in this group are progesterone, adrenocortical hormones, the gonadal hormones, cardiac aglycones, bile acids, sterols (such as cholesterol), toad poisons, saponins, and some of the carcinogenic hydrocarbons.
Chemically, compounds that contain the cyclopenteno-phenanthrene ring system. All the biologically important steroids are derived metabolically from cholesterol; they include the sex hormones (androgens, oestrogens and progesterone) and the hormones of the adrenal cortex.
A chemical compound composed of a series of four carbon rings joined together to form a (molecular) structural unit called cyclopentanoperhydrophenanthrene. Any of a group ofnaturally occurring, fat-soluble substances, essential to life, usually classed as lipids. Steroids of importance to the body are the sterols, which are bile acids (produced by the liver, characterized by the presence of a carboxyl group in the molecule’s side chain), and the hormones of the sex glands and the adrenal cortex. In addition, the plant kingdom possesses a wide variety of steroid glycosides.

Active chemicals, of animal and plant origin, with powerful hormonal action.
Any of several chemical compounds, including the sex hormones, which have characteristic ring systems and which affect the body and its functions.
The general term used to describe a group of hormones and their analogs that have a common chemcial configuration but are divided into several categories depending on their primary physiologic effects. Common types of steroids include the glucocorticoids (cortisone, prednisone, many others), mineralocorticoids (aldosterone), androgens/anabolic steroids (testosterone), and steroids related to female physiologic function (estrogen, progesterone).
One of a large group of substances produced by or related to those produced the adrenal gland. These include corticosteroids and mineralocorticoids, as well as sex hormones.
One of a group of compounds having a common structure based on the steroid nucleus, which consists of three six membered carbon rings and one five-membered carbon ring. The naturally occurring steroids include the male and female sex hormones (androgens and estrogens), the hormones of the adrenal cortex, progesterone, bile salts, and sterols. Synthetic steroids have been produced for therapeutic purposes.
The group name for compounds that resemble cholesterol chemically. The group includes the sex hormones, the hormones of the adrenal cortex, and bile acids. They have a powerful influence on the normal functioning of the body, and natural and synthetic steroids are used in the treatment of many disorders.
A biochemical compound derived from cholesterol includes the sex hormones oestrogen, progesterone and testosterone.
The broad term includes a large number of chemicals including vitamin D, cortisone, testosterone, estrogen, and bile acids.
A medication employed to alleviate inflammation and mitigate the buildup of fluid.
This term is employed to characterize either an inherent hormone found in nature or a synthetic steroid medication. Steroid hormones encompass sex hormones and those generated by the adrenal glands. Meanwhile, steroid drugs encompass corticosteroids and anabolic steroids.
A category of compounds that are chemically similar to cholesterol. This group encompasses sex hormones, bile acids, sterols, and certain hydrocarbons that can promote cancer.
