Galacturonic acid ( or, more specifically D-galacturonic acid ) is an organic chemical compound from the group of uronic acids. It comes as a major component of pectins before (which was first suspected in 1924 by K. Smolenski ) and belongs to the fiber. Is formally an oxidized form of the D-galactose. Its salts are called Galacturonate.
