title: Structure of the O-specific polysaccharide of Proteus vulgaris O25 containing 3-O-[(R)-1-carboxyethyl]-D-glucose.
abstract: The O-specific polysaccharide of Proteus vulgaris O25 was studied by acid hydrolysis and by 1H-NMR and 13C-NMR spectroscopies, including one-dimensional NOE and two-dimensional COSY and heteronuclear 13C,1H correlation (HETCOR) spectroscopy. The polysaccharide was found to contain 3-O-[(R)-1-carboxyethyl]-D-glucose (D-RGlc), and the following structure of the pentasaccharide repeating unit was established: [structure in text]
