The molecule is an amino oligosaccharide that is a branched tridecasaccharide derivative in which beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminyl-(1->2)-[beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminyl-(1->6)-alpha-D-mannosyl and beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminyl-(1->2)-[beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminyl-(1->4)-alpha-D-mannosyl branched pentasaccharide units 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-beta-D-glucosamine trisaccharide. It is an amino oligosaccharide and a glucosamine oligosaccharide.
