Chemical Information
FooDB NameEpicatechin-(4beta->8)-epicatechin 3'-gallate
DescriptionEpicatechin-(4beta->8)-epicatechin 3'-gallate 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''. Epicatechin-(4beta->8)-epicatechin 3'-gallate is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Epicatechin-(4beta->8)-epicatechin 3'-gallate can be synthesized from gallic acid. Epicatechin-(4beta->8)-epicatechin 3'-gallate can also be synthesized into procyanidin B2. Epicatechin-(4beta->8)-epicatechin 3'-gallate can be found in common buckwheat, common grape, and tea, which makes epicatechin-(4beta->8)-epicatechin 3'-gallate a potential biomarker for the consumption of these food products.
