{6)-[beta-d-glcpa-(1->3)]-beta-d-galpnac-(1->}n
A polysaccharide derivative consisting of a chain of 2-acetamido-2-deoxy-β-<small>D</small>-galactopyranose units joined  together by (1→6)-glycosidic linkages, with each unit substituted by a β-<small>D</small>-glucopyranuronic acid, attached by a (1→3) linkage.
