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. Uttronin a is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Uttronin a can be found in soft-necked garlic, which makes uttronin a a potential biomarker for the consumption of this food product.
