- Definition
- A polysaccharide derivative comprised of a [2)-alpha-L-Rhap(III)-(1->2)-alpha-L-Rhap(II)-(1->3)-alpha-L-Rhap(I)-(1->3)-beta-D-GlcpNAc-(1->] tetrasaccharide repeat modified by the (1->4) linkage of an alpha-D-glucosyl group to the Rha(I) residue and by addition of an acetyl group to 50% of the O-6 positions of the GlcNAc residue. The structure provided is representative of that in Shigella flexneri serotype 2a and shows the repeating unit containing the acetyl group on the GlcNAc residue.
