描述
1,2,3-tri-o-galloyl-beta-4c1-glucose is a member of the class of compounds known as tannins. Tannins 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). 1,2,3-tri-o-galloyl-beta-4c1-glucose is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). 1,2,3-tri-o-galloyl-beta-4c1-glucose can be found in pomegranate, which makes 1,2,3-tri-o-galloyl-beta-4c1-glucose a potential biomarker for the consumption of this food product.
