Androstane is a C19 steroidal hydrocarbon with a gonane core. Androstane can exist as either of two isomers, known as 5α-androstane and 5β-androstane.

• 5α-Androstane
• 5β-Androstane

Pharmacology

5α-Androstane is reported to be effective as an androgen, in spite of having no oxygen containing functional groups.

Androstanes

Androstanes are steroid derivatives with carbons present at positions 1 through 19.
