Metabolite Identification
Common NamePhysalin G
DescriptionPhysalin G belongs to the class of organic compounds known as physalins and derivatives. These are steroidal constituents of Physalis plants which possess an unusual 13,14-seco-16,24-cyclo-steroidal ring skeleton (where the bond that is normally present between the 13 and 14 positions in other steroids is broken while a new bond between positions 16 and 24 is formed). Physalin G is an extremely weak basic (essentially neutral) compound (based on its pKa).
