The molecule is a branched amino oligosaccharide that is a pentadecasaccharide comprising a linear trisaccharide of beta-D-mannose and two N-acetyl-beta-D-glucosamine residues all linked in sequence (1->4), to the mannosyl residue of which are linked an N-acetyl-beta-D-glucosaminyl residue [via a (1->4) linkage], an N-acetyl-alpha-neuraminyl-(2->6)-beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminyl-(1->2)-[N-acetyl-alpha-neuraminyl-(2->6)-beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminyl-(1->6)]-alpha-D-mannosyl branched heptasaccharide unit [linked (1->6)], and an N-acetyl-alpha-neuraminyl-(2->6)-beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminyl-(1->2)-alpha-D-mannopyranosyl linear tetrasaccharide unit [linked (1->3)]. It is a glucosamine oligosaccharide and an amino oligosaccharide.
