[Antigenic bacterial polysaccharides. 24. The structure of the O-specific polysaccharide chain of Salmonella arizonae 063 (Arizona 08) lipopolysaccharide].

The O-specific polysaccharide chain of the Salmonella arizonae O63 lipopolysaccharide is composed of D-glucose, D-galactose, N-acetyl-D-galactosamine, and 3-acetamido-3,6-dideoxy-D-galactose (Fuc3NAc) residues in the ratio 1:1:2:1. On the basis of methylation analysis and calculations of 13C-NMR-spectra of the polysaccharide and of the product of its selective cleavage with anhydrous hydrogen fluoride, the linear polymer lacking 3-acetamido-3,6-dideoxygalactose, it was concluded that the polysaccharide has the following structure: (Formula: see text).
