The molecule is an amino disaccharide consisting of 2-acetamido-2-deoxy-beta-D-galactopyranose and D-galactopyranose residues joined in sequence by a (1->6) glycosidic bond. It is a N-acyl-hexosamine, an amino disaccharide and a member of acetamides. It derives from a D-galactopyranose and a D-tyrosine.
