The molecule is a branched amino nonasaccharide consisting of an alpha-D-galactosamine residue to which are attached (1->3) and (1->6) two beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminyl-(1->3)-beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminyl tetrasaccharide branches. It is an amino nonasaccharide, a galactosamine oligosaccharide and a glucosamine oligosaccharide.
