Galactopyranosiduronic acid

Pectin and pectic acid, which are the natural substrates of pectic enzymes, are branched heteropolysaccharides in which the backbone contains L-rhamnose residues and a-D-(l — 4)-linked residues of D-galactopyranosiduronic acid. The neutral sugars D-galactose and L-arabinose, and sometimes D-xylose and L-fucose, form the side...
