Chemical Information
FooDB NamePinotin A
DescriptionPinotin A belongs to the class of organic compounds known as biflavonoids and polyflavonoids. These are organic compounds containing at least two flavan/flavone units. These units are usually linked through CC or C-O-C bonds. Some examples include C2-O-C3, C2-O-C4, C3'-C3''', and C6-C8''. Pinotin A is an extremely weak basic (essentially neutral) compound (based on its pKa). Pinotin A is found, on average, in the highest concentration within grape wines. Pinotin A has also been detected, but not quantified in, common grapes. This could make pinotin a a potential biomarker for the consumption of these foods.
