The molecule is an amino octasaccharide in which an N-acetyl-beta-D-glucosaminyl-(1->2)-alpha-D-mannosyl disaccharide chain and a beta-D-galactosyl-(1->3)-N-acetyl-beta-D-glucosaminyl-(1->2)-alpha-D-mannosyl chain are linked (1->6) and (1->3) respectively to the mannose residue of a beta-D-mannosyl-(1->4)-N-acetyl-beta-D-glucosaminyl-(1->4)-N-acetyl-D-glucosamine trisaccharide. It is a glucosamine oligosaccharide and an amino octasaccharide.
