A polysaccharide derivative composed of a backbone of repeating β-<small>D</small>-galactosyl-(1→4)-<em>N</em>-acetyl-β-<small>D</small>-glucosaminyl-(1→3)-β-<small>D</small>-galactosyl-(1→4)-β-<small>D</small>-glucosyl that are joined via (1→6)-linkages between the glucosyl and <em>N</em>-acetylglucosaminyl residues.
