Steroids are a large group of naturally occurring and synthetic chemicals that promote cell growth and division. Steroid hormones are all characterized by the steroid nucleus, which comprises three six-member rings and one five member ring. The steroid nucleus has six asymmetric carbons which provides many stereoisomers that help differentiate different steroid hormones (Steroid Structure). Some basic questions about steroids are listed below. Click on the links to learn more.
