alpha-D-GlcNS6S-(1->4)-beta-D-IdoA2S-(1->4)-alpha-D-GlcNS3S-(1->4)-beta-D-GlcA-(1->3)-beta-D-Gal-(1->3)-beta-D-Gal-(1->4)-beta-D-Xyl-yl group
A linear heptasaccharide glycosyl group consisisting of one iduronic acid residue sulfated on O-2, two glucosamine residues, both sulfated on nitrogen and with one also sulfated at O-3 and the other sulfated at O-6, 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.
