| Common Name | Fistuloside B |
|---|
| Description | Fistuloside B 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. Fistuloside B is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, fistuloside b has been detected, but not quantified in, onion-family vegetables. This could make fistuloside b a potential biomarker for the consumption of these foods. |
