Metabolite Identification
Common NameMelongoside G
DescriptionMelongoside G belongs to the class of organic compounds known as steroidal saponins. These are saponins in which the aglycone moiety is a steroid. The steroidal aglycone is usually a spirostane, furostane, spirosolane, solanidane, or curcubitacin derivative. Melongoside G is an extremely weak basic (essentially neutral) compound (based on its pKa).
