Metabolite Identification
Common NamePhysapubenolide
DescriptionPhysapubenolide 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. Thus, physapubenolide is considered to be a sterol lipid molecule. Physapubenolide is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
