Pregnane, also known as 17β-ethylandrostane or as 10β,13β-dimethyl-17β-ethylgonane, is a C21 steroid and, indirectly, a parent of progesterone. It is a parent hydrocarbon for two series of steroids stemming from 5α-pregnane (originally allopregnane) and 5β-pregnane (17β-ethyletiocholane). It has a gonane core.
Pregnanes are steroid derivatives with carbons present at positions 1 through 21.
Pregnenes have a double bond. Examples include:
Pregnadienes have two double bonds. Examples include:
