Chemical Information
FooDB NameManoyl oxide
DescriptionManoyl oxide, also known as (-)-ent-13-epi-manoyl oxide, is a member of the class of compounds known as triterpenoids. Triterpenoids are terpene molecules containing six isoprene units. Manoyl oxide is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Manoyl oxide can be found in pot marjoram, which makes manoyl oxide a potential biomarker for the consumption of this food product.
