The molecule is a branched amino oligosaccharide (tetradecasaccharide) consisting of a linear trisaccharide unit of beta-D-mannose, N-acetyl-beta-D-glucosamine and N-acetyl-D-glucosamine residues, connected by (1->3) linkages, to the beta-D-mannose residue of which are linked (1->3) and (1->6) alpha-D-mannose residues, the one at O-2 being substituted at O-2 by an N-acetyl-beta-D-glucosaminyl-(1->3)-beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminyl trisaccharide unit and the one at O-6 being substituted also at both O-2 and O-6 by N-acetyl-beta-D-glucosaminyl-(1->3)-beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminyl trisaccharide units.
