Chemical Information
FooDB NameMaysin
DescriptionMaysin belongs to the class of organic compounds known as flavonoid c-glycosides. Flavonoid C-glycosides are compounds containing a carbohydrate moiety which is C-glycosidically linked to the 2-phenylchromen-4-one flavonoid backbone. Maysin is an extremely weak basic (essentially neutral) compound (based on its pKa). Maysin has been detected, but not quantified in, cereals and cereal products and corns. This could make maysin a potential biomarker for the consumption of these foods.
