The molecule is an amino oligosaccharide that is a dodecasaccharide derivative consisting of a tetrasaccharide chain of N-acetyl-beta-D-glucosamine, beta-D-mannose, N-acetyl-beta-D-glucosamine and N-acetyl-D-glucosamine residues, all linked sequentially (1->4), to the beta-D-mannose residue of which are also linked beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminyl-(1->2)-alpha-D-mannosyl and beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminyl-(1->4)-[beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminyl-(1->2)]-alpha-D-mannosyl units via (1->6) and (1->3) linkages respectively. It is an amino oligosaccharide and a glucosamine oligosaccharide.
