Metabolite Identification
Common NameIxocarpalactone B
DescriptionIxocarpalactone B 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. Ixocarpalactone B is an extremely weak basic (essentially neutral) compound (based on its pKa).
