The molecule is an amino oligosaccharide that is a branched tridecasaccharide in which two beta-D-Gal-(1->4)-beta-D-GlcNAc disaccharide units are linked (1->2) and (1->4) to the terminal mannose residue of an alpha-D-Man-(1->3)-beta-D-Man-(1->4)-beta-D-GlcNAc-(1->4)-D-GlcNAc tetrasaccharide chain, to the beta-D-mannose residue of which is also linked (1->6) a beta-D-Gal-(1->4)-beta-D-GlcNAc-(1->3)-alpha-D-Man trisaccharide unit. It has a role as an epitope. It is an amino oligosaccharide and a glucosamine oligosaccharide.
