(A) Schematic structure of LPS molecule: O-specific antigen chain has a variable length, thus the amount of sialic acid residues per LPS molecule can vary from none (in rough LPS) up to over one hundred (in so-called very-long-O-antigen LPS); (B) Chemical structures of most common members of neuraminic acids family: N-acetylneuraminic acid (Neu5Ac), 2-keto-3-deoxy-nonulosonic acid (Kdn), N-glycolylneuraminic acid (Neu5Gc), legionaminic acid (Leg), and pseudaminic acid (Pse), presented in simplified Fisher projection formula.
