Metabolite Identification
Common NameGranatin B
DescriptionGranatin B belongs to the class of organic compounds known as hydrolyzable tannins. These are tannins with a structure characterized by either of the following models. In model 1, the structure contains galloyl units (in some cases, shikimic acid units) that are linked to diverse polyol carbohydrate-, catechin-, or triterpenoid units. In model 2, contains at least two galloyl units C-C coupled to each other, and do not contain a glycosidically linked catechin unit. Granatin B is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, granatin b has been detected, but not quantified in, fruits and pomegranates. This could make granatin b a potential biomarker for the consumption of these foods. Granatin B is an ellagitannin found in the fruit of Punica granatum (pomegranate). It is a molecule having an enantiomeric dehydrohexahydroxydiphenoyl group. It is a highly active carbonic anhydrase inhibitor.

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.
