A linear octasaccharide glycosyl group consisisting of two glucuronic acid residues, two glucosamine residues, both sulfated on nitrogen, one idouronic acid residue sulfated on O-2, and two galactose residues linked to a xylosyl residue at the reducing end and which is commonly bonded to an amino acid residue.
