The molecule is an amino disaccharide consisting of beta-D-galacopyranose and 2-acetamido-2-deoxy-beta-D-galactopyranose residues joined in sequence by a (1->4) glycosidic linkage. It is an amino disaccharide and a member of acetamides. It derives from a N-acetyl-beta-D-galactosamine and a beta-D-galactose.
