The molecule is an amino disaccharide consisting of beta-D-galactopyranose and 2-acetamido-2-deoxy-alpha-D-glucopyranose residues joined in sequence by a (1->6) glycosidic bond. It is a glycosylglucose derivative, an amino disaccharide and a member of acetamides. It derives from a beta-D-galactose and a N-acetyl-alpha-D-glucosamine.
