Chemical Information
FooDB Name3'-Methylepicatechin 4'-glucuronide
Description(2S,3S,4S,5R,6S)-3,4,5-trihydroxy-6-{2-methoxy-4-[(2R,3R)-3,5,7-trihydroxy-3,4-dihydro-2H-1-benzopyran-2-yl]phenoxy}oxane-2-carboxylic acid belongs to the class of organic compounds known as flavonoid o-glucuronides. These are phenolic compounds containing a flavonoid moiety which is O-glycosidically linked to glucuronic acid (2S,3S,4S,5R,6S)-3,4,5-trihydroxy-6-{2-methoxy-4-[(2R,3R)-3,5,7-trihydroxy-3,4-dihydro-2H-1-benzopyran-2-yl]phenoxy}oxane-2-carboxylic acid is an extremely weak basic (essentially neutral) compound (based on its pKa).
