Identification
Common Name6-Keto-28-homobrassinolide
ClassSmall Molecule
Description6-keto-28-homobrassinolide belongs to stigmastanes and derivatives class of compounds. Those are sterol lipids with a structure based on the stigmastane skeleton, which consists of a cholestane moiety bearing an ethyl group at the carbon atom C24. 6-keto-28-homobrassinolide is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 6-keto-28-homobrassinolide can be found in tea, which makes 6-keto-28-homobrassinolide a potential biomarker for the consumption of this food product.
