The molecule is an amino oligosaccharide that is a branched decasaccharide derivative comprised of a mannose residue to which is linked an N-acetylgalactosaminyl residue at O-2, a glucosyl residue at O-3 and a beta-D-QuiN4Fm-(1->4)-alpha-D-GalNAcAN-(1->4)-alpha-D-GalNAcAN-(1->3)-beta-D-QuiNAc tetrasaccharide chain at O-4, all linked to an [alpha-D-Glc-(1->2)]-alpha-D-Man-(1->5)-alpha-Kdo branched trisaccharide unit. It is an amino oligosaccharide and a galactosamine oligosaccharide.
