| Common Name | Epicatechin-(2beta->7,4beta->8)-[epicatechin-(4beta->8)]2-catechin |
|---|
| Description | Epicatechin-(2beta->7,4beta->8)-[epicatechin-(4beta->8)]2-catechin 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-(2beta->7,4beta->8)-[epicatechin-(4beta->8)]2-catechin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Epicatechin-(2beta->7,4beta->8)-[epicatechin-(4beta->8)]2-catechin can be found in lingonberry, which makes epicatechin-(2beta->7,4beta->8)-[epicatechin-(4beta->8)]2-catechin a potential biomarker for the consumption of this food product. |
