描述
Chakasaponin iii is a member of the class of compounds known as triterpene saponins. Triterpene saponins are glycosylated derivatives of triterpene sapogenins. The sapogenin moiety backbone is usually based on the oleanane, ursane, taraxastane, bauerane, lanostane, lupeol, lupane, dammarane, cycloartane, friedelane, hopane, 9b,19-cyclo-lanostane, cycloartane, or cycloartanol skeleton. Chakasaponin iii is slightly soluble (in water) and a weakly acidic compound (based on its pKa). Chakasaponin iii can be found in tea, which makes chakasaponin iii a potential biomarker for the consumption of this food product.
