Synonyms

[2)-alpha-L-Rha(III)3/4Ac-(1->2)-alpha-L-Rha(II)-(1->3)-[alpha-D-Glc-(1->4)]-alpha-L-Rha(I)-(1->3)-beta-D-Glc6,NAc2-(1->]n
[2)-alpha-L-Rhap(III)3/4Ac-(1->2)-alpha-L-Rhap(II)-(1->3)-[alpha-D-Glcp-(1->4)]-alpha-L-Rhap(I)-(1->3)-beta-D-Glcp6,NAc2-(1->]n

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 acetyl groups to 60% of the O-6 positions of the GlcNAc residue and to either O-3 or O-4 of many of the Rha(III) residues (60% to O-3; 25% to O-4). The structure provided is representative of that in Shigella flexneri serotype 2a and shows the most common repeating unit.
