Metabolite Identification
Common NameOryzalexin D
DescriptionOryzalexin d, also known as 3alpha,7beta-dihydroxy-ent-sandaracopimaradiene or ent-sandaracopimaradien-3alpha,7beta-diol, is a member of the class of compounds known as diterpenoids. Diterpenoids are terpene compounds formed by four isoprene units. Oryzalexin d is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Oryzalexin d can be found in rice, which makes oryzalexin d a potential biomarker for the consumption of this food product.
