Chemical Information
FooDB Name1,2,6-Trigalloyl-beta-D-glucopyranose
Description1,2,6-Trigalloyl-beta-D-glucopyranose belongs to the class of organic compounds known as tannins. These are naturally occurring polyphenols which be categorized into four main classes: hydrolyzable tannin (based on ellagic acid or gallic acid), condensed tannins (made of oligomeric or polymeric proanthocyanidins), complex tannins (made of a catechin bound to a gallotannin or elagitannin), and phlorotannins (oligomers of phloroglucinol). 1,2,6-Trigalloyl-beta-D-glucopyranose is an extremely weak basic (essentially neutral) compound (based on its pKa). 1,2,6-Trigalloyl-beta-D-glucopyranose has been detected, but not quantified in, several different foods, such as fruits, garden rhubarbs, pomegranates, and red raspberries. This could make 1,2,6-trigalloyl-beta-D-glucopyranose a potential biomarker for the consumption of these foods.
