N-acetyl-beta-D-glucosaminyl-(1->3)-[(->3)beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminyl(1->)]n
n-acetyl-beta-d-glucosaminyl-(1->3)-[(->3)beta-d-galactosyl-(1->4)-n-acetyl-beta-d-glucosaminyl(1->)]n
A glycosaminoglycan composed of a <em>N</em>-acetyl-β-<small>D</small>-glucosamine moiety attached via a (1→3) linkage to a backbone of repeating β-<small>D</small>-galactosyl-(1→4)-<em>N</em>-acetyl-β-<small>D</small>-glucosamine units joined by (1→3) linkages.
