1,6-di-O-Galloylglucose
IUPAC 名称
[(2R,3S,4S,5R,6S)-3,4,5-trihydroxy-6-(3,4,5-trihydroxybenzoyloxy)oxan-2-yl]methyl 3,4,5-trihydroxybenzoate
描述
1,6-di-o-galloylglucose, also known as 1-o,6-O-digalloyl-beta-D-glucose or dgg16 cpd, 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). 1,6-di-o-galloylglucose is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). 1,6-di-o-galloylglucose can be found in garden rhubarb, which makes 1,6-di-o-galloylglucose a potential biomarker for the consumption of this food product.
