title: Structural studies of the O-specific chain and a core hexasaccharide of Hafnia alvei strain 1192 lipopolysaccharide.
abstract: The structure of the O-specific side-chain and a core hexasaccharide of the Hafnia alvei strain 1192 lipopolysaccharide has been investigated. Methylation analysis, NMR spectroscopy, MALDI-TOF spectrometry, and various specific chemical degradations were the principal methods used. It is concluded that the polysaccharide is composed of hexasaccharide repeating-units having the following structure which is partially O-acetylated in the 2-position of the --> 4)-alpha-D-Glc pA-(1-->(70%) and on different positions of the L-Rha residues (50%). [Formula: see text] The core hexasaccharide was found to have the following structure: [Formula: see text]
