Common Name[Epicatechin-(4beta->8)]2-epicatechin 3'''-gallate
Description[epicatechin-(4beta->8)]2-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)]2-epicatechin 3'''-gallate is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). [epicatechin-(4beta->8)]2-epicatechin 3'''-gallate can be found in common grape, which makes [epicatechin-(4beta->8)]2-epicatechin 3'''-gallate a potential biomarker for the consumption of this food product.
