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. Thus, spinosterol is considered to be a sterol lipid molecule. Spinosterol is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Spinosterol can be found in wild celery, which makes spinosterol a potential biomarker for the consumption of this food product.
