Metabolite Identification
Common NamePubescenol
DescriptionPubescenol belongs to the class of organic compounds known as withanolides and derivatives. These are c28 steroids structurally characterized by an ergostane skeleton usually functionalized at carbons 1, 22 and 26 to form a lactone ring. Pubescenol is an extremely weak basic (essentially neutral) compound (based on its pKa).
