title: Core region of Citrobacter O23 lipopolysaccharide. Structure elucidation by chemical methods, gas chromatography/mass spectrometry and NMR spectroscopy at 500 MHz.
abstract: A novel enterobacterial core region in Citrobacter O23 lipopolysaccharide is described. Its structure was determined by methylation analysis/mass spectrometry, chemical degradation and one- and two-dimensional 1H-NMR spectroscopy: [formula; see text] where PPEtN stands for diphosphorylethanolamine, and dOclA for 3-deoxy-D-manno-octulosonic acid.
