title: Chemical characterization of a new 5,7-diamino-3,5,7,9-tetradeoxynonulosonic acid released by mild acid hydrolysis of the Legionella pneumophila serogroup 1 lipopolysaccharide.
abstract: A derivative of a new 5,7-diamino-3,5,7,9-tetradeoxynonulosonic acid was released from the lipopolysaccharide of Legionella pneumophila serogroup 1 (strain Philadelphia 1) by mild acid hydrolysis, and identified, using NMR spectroscopy and GLC-MS, as 5,7-diacetamido-8-O-acetyl-3,5,7,9-tetradeoxy-L-glycero-D-talo- nonulosonic acid or its enantiomer.
