Metabolite Identification
Common NameTaraxasterol acetate
DescriptionTaraxasterol acetate, also known as urs-20(30)-en-3-ol acetate, is a member of the class of compounds known as triterpenoids. Triterpenoids are terpene molecules containing six isoprene units. Taraxasterol acetate is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Taraxasterol acetate can be found in burdock, which makes taraxasterol acetate a potential biomarker for the consumption of this food product.
