The molecule is a branched amino octasaccharide consisting of a pentasaccharide chain of N-acetyl-beta-D-glucosamine, alpha-D-mannose, beta-D-mannose and two further N-acetyl-beta-D-glucosamine residues linked sequentially (1->2), (1->3), (1->4) and (1->4), to the beta-D-mannose residue of which is also linked (1->6) an N-acetyl-beta-D-glucosaminyl-(1->2)-[N-acetyl-beta-D-glucosaminyl-(1->6)]-alpha-D-mannosyl trisaccharide unit. It is an amino octasaccharide and a glucosamine oligosaccharide.
