Description3-epidemissidine belongs to solanidines and derivatives class of compounds. Those are steroids with a structure based on the solanidane skeleton. Solanidane arises from the conversion of a cholestane side-chain into a bicyclic system. 3-epidemissidine is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). 3-epidemissidine can be found in alcoholic beverages, potato, and root vegetables, which makes 3-epidemissidine a potential biomarker for the consumption of these food products.
