Metabolite Identification
Common NameGitonin
DescriptionF-gitonin is a member of the class of compounds known as steroidal saponins. Steroidal saponins are saponins in which the aglycone moiety is a steroid. The steroidal aglycone is usually a spirostane, furostane, spirosolane, solanidane, or curcubitacin derivative. F-gitonin is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). F-gitonin can be found in soft-necked garlic, which makes F-gitonin a potential biomarker for the consumption of this food product.
