The complete structure for the core oligosaccharide region of the water-insoluble low-Mr, lipopolysaccharide of Campylobacter jejuni serotype 0:3 from phenol/water extraction of bacterial cells was assigned through studies on derivatives of the liberated oligosaccharide. Structure determinations were performed using 1H-NMR and 31P-NMR spectroscopies, methylation analysis supported by fast-atom-bombardment mass spectrometry, and Smith degradation experiments. It was concluded that the complete chains in the core oligosaccharide had the following structure in which a proportion of the terminal residues were phosphorylated: . From a similar series of experiments, it was concluded that an associated polysaccharide, which was isolated from the water phase of the phenoVwater extracts, had the following repeating unit in which a proportion of the previously unknown L-glycero-D-ido-heptose (L-a-D-ido-Hep) residues were present as 3-hydroxypropanoyl esters, and were not covalently linked to the lipopolysaccharide: -[ā3)-L-a-D-Ido-Hep-(lā4)-a-D-Gal-(l-]n-.
