Common Name | [Gallocatechin(4alpha->8)]2catechin |
---|
Description | [Gallocatechin(4alpha->8)]2catechin 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)]2catechin 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)]2catechin a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on [Gallocatechin(4alpha->8)]2catechin. |
