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