DescriptionSimmondsin belongs to the class of organic compounds known as o-glycosyl compounds. These are glycoside in which a sugar group is bonded through one carbon to another group via a O-glycosidic bond. Simmondsin is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, Simmondsin has been detected, but not quantified in, a few different foods, such as coffee and coffee products, fats and oils, and nuts. This could make simmondsin a potential biomarker for the consumption of these foods. Simmondsin is a component of jojoba seeds (pronounced "ho-HO-bah") (Simmondsia chinensis).
