[6)-alpha-d-glcp-(1->4)-alpha-d-neup5,7ac2-(2->]n
A polysaccharide derivative that consists of a backbone of α-<small>D</small>-glucosyl-(1→4)-5,7-diacetyl-α-<small>D</small>-neuraminosyl repeating units, joined together by glycosidic linkages between position 2 of the diacetylneuraminosyl residues and position 6 of the glucosyl residues. The depicted structure is representative and shows the repeating unit, which is variably <em>O</em>-acylated at the 7-position of the neuraminosyl residues.
