The nomenclature of steroids is a subset of the nomenclature of natural products.[1]

Definitions

A steroid is a compound (either naturally occurring or artificial) based on the cyclopenta[a]phenanthrene carbon skeleton, partially or completely hydrogenated.[2][3] Steroids usually have methyl groups at C-10 and C-13, and often an alkyl group at C-17 (termed a "side chain"). By extension, one or more bond scissions, ring expansions and/or ring contractions of the skeleton may have occurred.[2][3] Sterols are steroids with a hydroxyl group at C-3.[3]
