Metabolite Identification
Common Nameent-Epicatechin-(4alpha->8)-ent-epicatechin 3-gallate
Descriptionent-Epicatechin-(4alpha->8)-ent-epicatechin 3-gallate, also known as 3-galloylprocyanidin B1 or procyanidin dimer B1 3-O-gallate, 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''. ent-Epicatechin-(4alpha->8)-ent-epicatechin 3-gallate has been detected, but not quantified in, fruits. This could make ent-epicatechin-(4alpha->8)-ent-epicatechin 3-gallate a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on ent-Epicatechin-(4alpha->8)-ent-epicatechin 3-gallate.

Enzymes

General function:
Lipid transport and metabolism
Specific function:
Involved in the detoxification of xenobiotics and in the activation of ester and amide prodrugs. Hydrolyzes aromatic and aliphatic esters, but has no catalytic activity toward amides or a fatty acyl-CoA ester. Hydrolyzes the methyl ester group of cocaine to form benzoylecgonine. Catalyzes the transesterification of cocaine to form cocaethylene. Displays fatty acid ethyl ester synthase activity, catalyzing the ethyl esterification of oleic acid to ethyloleate.
