Task: Please create a description for a molecule.
Molecule SMILES: CC(=O)N[C@@H]1[C@@H](O[C@@H]2O[C@@H](C)[C@H](O)[C@@H](O[C@@H]3O[C@@H](C)[C@H](O)[C@@H](O)[C@H]3O[C@@H]3O[C@@H](C)[C@H](O)[C@@H](OC(C)=O)[C@H]3O)[C@H]2O)[C@H](O[C@H]2O[C@H](CO)[C@@H](O)[C@H](O)[C@H]2O)[C@@H](CO)O[C@H]1O
Constraint: Answer the question with full sentences.
Result: The molecule is 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 GlcNAc residue and by addition of an acetyl group to either O-3 or O-4 of many of the Rha(III) residues (65% to O-3; 25% to O-4). The structure provided is representative of that in Shigella flexneri serotype 1a and shows the most common repeating unit. It has a role as an antigen.
