ChEBI ID CHEBI:78716
ChEBI ASCII Name S. flexneri serotype Y O-polysaccharide (O factor 9-positive)
Definition A polysaccharide derivative comprised of a [2)-α-L-RhapIII-(1→2)-α-L-RhapII-(1→3)-α-L-RhapI-(1→3)-β-D-GlcpNAc-(1→] tetrasaccharide repeat modified by addition of acetyl groups to 40% of the O-6 positions of the GlcNAc residue and to either O-3 or O-4 of many of the RhaIII residues (30% to O-3; 20% to O-4). The structure provided is representative of that in Shigella flexneri serotype Y and shows the most common repeating unit.

Any substance that stimulates an immune response in the body, such as through antibody production or by presentation to a T-cell receptor after binding to a major histocompability complex (MHC).
Related Structures
S. flexneri serotype Y O-polysaccharide (O factor 9-positive) is a Structural Derivative of
polysaccharide
Definition : A biomacromolecule consisting of large numbers of monosaccharide residues linked glycosidically. This term is commonly used only for those containing more than ten monosaccharide residues.
 carbohydrate
Definition : Any member of the class of organooxygen compounds that is a polyhydroxy-aldehyde or -ketone or a lactol resulting from their intramolecular condensation (monosaccharides); substances derived from these by reduction of the carbonyl group (alditols), by oxidation of one or more hydroxy groups to afford the corresponding aldehydes, ketones, or carboxylic acids, or by replacement of one or more hydroxy group(s) by a hydrogen atom; and polymeric products arising by intermolecular acetal formation between two or more such molecules (disaccharides, polysaccharides and oligosaccharides). Carbohydrates contain only carbon, hydrogen and oxygen atoms; prior to any oxidation or reduction, most have the empirical formula Cm(H2O)n. Compounds obtained from carbohydrates by substitution, etc., are known as carbohydrate derivatives and may contain other elements. Cyclitols are generally not regarded as carbohydrates.
