Metabolite Identification
Common NameOleanolic acid methyl ester
DescriptionOleanolic acid methyl ester is a member of the class of compounds known as triterpenoids. Triterpenoids are terpene molecules containing six isoprene units. Oleanolic acid methyl ester is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Oleanolic acid methyl ester can be found in common grape, which makes oleanolic acid methyl ester a potential biomarker for the consumption of this food product.
