A linear octasaccharide glycosyl group consisisting of two iduronic acid residues, one of which is sulfated on O-2,  two glucosamine residues, both sulfated on nitrogen and with one also sulfated at O-3, one glucuronic acid residue, and two galactose residues linked to a xylosyl residue at the reducing end and which is commonly bonded to an amino acid residue.
