(2R,3S,4R)-2-(3,4-dihydroxyphenyl)-8-[(2R,3S,4S)-2-(3,4-dihydroxyphenyl)-3,5,7-trihydroxy-3,4-dihydro-2H-1-benzopyran-4-yl]-4-[(2R,3S)-2-(3,4-dihydroxyphenyl)-3,5,7-trihydroxy-3,4-dihydro-2H-1-benzopyran-8-yl]-3,4-dihydro-2H-1-benzopyran-3,5,7-triol
描述
Procyanidin c2, also known as C-(4,8)-C-(4,8)-C or procyanidin trimer c2, is a member of the class of compounds known as biflavonoids and polyflavonoids. Biflavonoids and polyflavonoids 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''. Procyanidin c2 is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Procyanidin c2 can be found in barley, beer, and common grape, which makes procyanidin c2 a potential biomarker for the consumption of these food products.
