[4)-beta-d-glcpa-(1->4)-alpha-d-glcpnac6os-(1->]n
A sulfated glycosaminoglycan composed of a backbone of repeating β-<small>D</small>-glucuronosyl-(1→4)-<em>N</em>-acetyl-α-<small>D</small>-glucosamine units, variably <em>O</em>-sulfated at the 6-position of the glucosamine residues and joined by (1→4)-linkages. The structure provided is representative and shows the most common repeating unit
