Common Name | Epigallocatechin-(4beta->8)-epicatechin 3,3'-digallate |
---|
Description | Epigallocatechin-(4beta->8)-epicatechin 3,3'-digallate 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''. Epigallocatechin-(4beta->8)-epicatechin 3,3'-digallate is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Epigallocatechin-(4beta->8)-epicatechin 3,3'-digallate can be found in tea, which makes epigallocatechin-(4beta->8)-epicatechin 3,3'-digallate a potential biomarker for the consumption of this food product. |
