title: Structure of the O-specific polysaccharide from a marine bacterium Cellulophaga algicola.
abstract: The O-polysaccharide was isolated from the lipopolysaccharide of Cellulophaga algicola and studied by chemical analyses along with1H and13C NMR spectroscopy, including 2D1H,1H COSY, TOCSY, ROESY,1Н,13С HSQC, HMBC experiments. It was found that the polysaccharide is built up of branched pentasaccharide repeating units, containing D-mannose (Man), D-glucuronic acid (GlcA), N-acetyl-D-glucosamine (GlcNAc), two L-rhamnose (Rha) residues and O-acetyl groups in a non-stoichiometric amount and has the following structure.
