Common NameCeposide D
DescriptionCeposide D 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. Ceposide D is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, ceposide D has been detected, but not quantified in, garden onions and onion-family vegetables. This could make ceposide D a potential biomarker for the consumption of these foods.
