Digalacturonic acid

4-O-alpha-D-Galactopyranuronosyl-D-galacturonic acid, also known as digalacturonic acid or sodium digalacturonate, belongs to the class of organic compounds known as o-glucuronides. These are glucuronides in which the aglycone is linked to the carbohydrate unit through an O-glycosidic bond. 4-O-alpha-D-Galactopyranuronosyl-D-galacturonic acid is soluble (in water) and a moderately acidic compound (based on its pKa).
