Basic StructureLPS is a complex macromolecule composed of the biologically active lipid A moiety, covalently attached core oligosaccharide, and distally linked polysaccharide O-side chain. The O-antigen part consists of the following residues : -3)-β-D-GlcpNAc-(1-->2)-α-L-Rhap [branched to α-D-Glcp-(1-->3)] -(1-->2)-α-L-Rhap [branched to α-D-Glcp-(1-->3)] -(1-->3)-α-L-Rhap-(1-
