A group of polycyclic compounds closely related biochemically to TERPENES. They include
cholesterol, numerous hormones, precursors of certain vitamins, bile acids, alcohols
(STEROLS), and certain natural drugs and poisons. Steroids have a common nucleus,
a fused, reduced 17-carbon atom ring system, cyclopentanoperhydrophenanthrene. Most
steroids also have two methyl groups and an aliphatic side-chain attached to the nucleus.
