Structural formula: {0} (CAS {1})

Pregnenolone is a 20-oxo steroid that is pregn-5-ene substituted by a beta-hydroxy group at position 3 and an oxo group at position 20. It has a role as a mouse metabolite and a human metabolite. It is a 3beta-hydroxy-Delta(5)-steroid, a 20-oxo steroid and a C21-steroid. It derives from a hydride of a pregnane.
