title: [Antigenic polysaccharides of bacteria. 25. Structure of the O-specific polysaccharide chain of Pseudomonas cepacia 673/2 lipopolysaccharide containing L-glycero-D-manno-heptose].
abstract: O-Specific polysaccharide, consisting of D-rhamnose and L-glycero-D-manno-heptose (LD-Hep) in a 2 : 1 ratio, was obtained on the mild acid degradation of the Pseudomonas cepacia IMV 673/2 lipopolysaccharide; monosaccharide LD-Hep has not previously been found in O-specific chains of lipopolysaccharides. On the basis of methylation and 13C-NMR data, it was concluded that the polysaccharide is composed of trisaccharide repeating units having the following structure: ----3)-alpha-D-Rha-(1----3)-alpha-D-Rha-(1----2)-alpha-LD-Hep-(1----
