Metabolite Identification
Common NameOryzalexin C
DescriptionOryzalexin c is a member of the class of compounds known as diterpenoids. Diterpenoids are terpene compounds formed by four isoprene units. Oryzalexin c is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Oryzalexin c can be found in rice, which makes oryzalexin c a potential biomarker for the consumption of this food product.
