Occurrence of 3-acetamido-3,6-dideoxy-4-O-miethyl-L-glucose in the O-polysaccharide of Vibrio anguillarum

Abstract

The amino sugar 3-acetamido-3,6-dideoxy-4-O-methyl-L-glucose has been characterized in the O-polysaccharide obtained from the bacterial lipopolysaccharide of Vibrio anguillarum. The identity of 1,2,5-tri-O-acetyl-3-acetamido-3,6-dideoxy-4-O-methyl-L-glucitol has been established by electron-impact and chemical-ionization mass spectrometry and by a labeling procedure.
