ster·oid hor·mones

those hormones possessing the steroid ring system, for example, androgens, estrogens, adrenocortical hormones.

ster·oid hor·mones

(ster'oyd hor'mōnz)
Those hormones possessing the steroid ring system (e.g., androgens, estrogens, adrenocortical hormones).

steroid hormones

those secreted by the adrenal cortex, the testis and the ovary, all made from cholesterol as precursor. A variety of synthetic steroids is used in treatment mainly of rheumatic conditions or of relevant hormonal disorders; others are marketed for body-building. See also aldosterone, anabolic steroids, androgens, glucocorticoids, hormones.

steroid

a complex molecule containing carbon atoms in four interlocking rings forming a hydrogenated cyclopentophenanthrene-ring system; three of the rings contain six carbon atoms each and the fourth contains five.
Steroid derivatives are important in body chemistry. Among them are the male and female sex hormones, such as testosterone and estrogen, and the hormones of the cortices of the adrenal glands, including cortisone. Vitamins of the D group are steroids involved in calcium metabolism. The cardiac glycosides, a group of compounds derived from certain plants, are partly steroids. Sterols, including cholesterol, are steroids. Cholesterol is the main building block of steroid hormones in the body; it is also converted into bile salts by the liver.
