Definition

A polysaccharide derivative comprised of a [2)-α-L-Rhap^III-(1→2)-α-L-Rhap^II-(1→3)-β-D-GalpA-(1→3)-β-D-GalpNAc-(1→] tetrasaccharide repeat modified by the addition of an acetyl group to either O-3 or O-4 of many of the Rha^III residues (60% to O-3; 30% to O-4). The structure provided is representative of that in Shigella flexneri serotype 6 and shows the most common repeating unit.
