as a result of the identification of all oligosaccharides obtained and comparative analysis of the 13c nuclear magnetic resonance spectra of the oligosaccharides and lipopolysaccharides the following structures were established for the repeating units of the polysaccharide chains of the lipopolysaccharides : ( formula : see text ) where d-xyl = d-xylose , d-fucnac = 2-acetamido-2,6-dideoxy-d-galactose , pse5n7nfm = 5-amino-3,5,7,9-tetradeoxy-7-formamido-l-glycero-l-manno-nonulosonic+ ++ acid ( 7-n-formylpseudaminic acid ) .
