The molecule is a branched amino oligosaccharide (dodecasaccharide) comprising two beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminyl disaccharide units linked (1->2) and (1->6) to the alpha-D-mannosyl residue of an alpha-D-mannosyl-(1->6)-beta-D-mannosyl-(1->4)-N-acetyl-beta-D-glucosaminyl-(1->4)-[alpha-L-fucosyl-(1->6)]-N-acetyl-beta-D-glucosamine branched pentasaccharide, to the beta-D-mannosyl residue of which is also linked (1->3) a beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminyl-(1->2)-alpha-D-mannosyl linear trisaccharide unit. It is an amino oligosaccharide and a glucosamine oligosaccharide.
