title: Configurations of glycosidic phosphates of lipopolysaccharide from Salmonella minnesota R595.
abstract: The anomeric configurations of the reducing terminal glucosamine and 4-amino-4-deoxy-L-arabinose phosphates in lipopolysaccharide from Salmonella minnesota R595 have been determined by nuclear magnetic resonance. Chemical shifts for the anomeric protons were obtained by selective decoupling of the phosphorus spectrum and proton-proton coupling constants by polarization transfer from protons to phosphorus. In both cases, the phosphate is attached to the sugar in an axial orientation.
