Steroid
hormones and their receptors include estrogens, progesterone, and androgens. They are manufactured from one common parent molecule, cholesterol, via a reaction catalyzed by several enzymes (Weinberg et al., 2005). Estrogen is produced by two different organ systems.
Which hormone is a steroid?

major classes of steroid hormones: progestins, androgens, estrogens, and corticoids, which contain 21, 19, 18, and 21 carbons, respectively. Steroid hormones are synthesized by dehydrogenases and cytochrome P450 enzymes, which catalyze hydro- xylation and dehydroxylation-oxidation reactions.
