| Common Name | Gallocatechin-(4alpha->8)-catechin-(4alpha->8)-catechin |
|---|
| Description | Gallocatechin-(4alpha->8)-catechin-(4alpha->8)-catechin belongs to the class of organic compounds known as biflavonoids and polyflavonoids. These 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''. Gallocatechin-(4alpha->8)-catechin-(4alpha->8)-catechin has been detected, but not quantified in, a few different foods, such as barleys (Hordeum vulgare), breakfast cereal, and cereals and cereal products. This could make gallocatechin-(4alpha->8)-catechin-(4alpha->8)-catechin a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Gallocatechin-(4alpha->8)-catechin-(4alpha->8)-catechin. |
