title: Structure of the O-specific polysaccharide from the lipopolysaccharide of Psychrobacter cryohalolentis K5(T) containing a 2,3,4-triacetamido-2,3,4-trideoxy-L-arabinose moiety.
abstract: A novel constituent of bacterial polysaccharides, 2,3,4-triacetamido-2,3,4-trideoxy-L-arabinose, was found in the O-specific polysaccharide from the lipopolysaccharide of Psychrobacter cryohalolentis K5(T) and identified by 1D and 2D (1)H and (13)C NMR studies of the polysaccharide and a disaccharide obtained by solvolysis of the polysaccharide with triflic acid. The following structure of the branched polysaccharide was established by sugar analysis, triflic acid solvolysis, Smith degradation, and 2D NMR spectroscopy.
