The molecule is a branched amino tetrasaccharide in which three N-acetyl-beta-D-glucosamine residues are linked (1->3), (1->4) and (1->6) to an N-acetyl-D-glucosamine residue with unspecified configuration at its anomeric centre. It has a role as an epitope. It is an amino tetrasaccharide and a glucosamine oligosaccharide.
