title: The structure of the O-antigenic side chain of the lipopolysaccharide of Vibrio cholerae 569B (Inaba).
abstract: Mineral acid hydrolysis of the lipopolysaccharide from Vibrio cholerae 569B (Inaba) gives an oligosaccharide fraction which was shown, by use of 13C NMR and chemical methods, to be a regular alpha-(1 leads to 2) linked chain of D-perosamine (4-amino-4,6-dideoxy-D-mannose) units. This chain represents the O-antigen of the lipopolysaccharide, in which the amino functions are acylated with 3-hydroxypropionyl groups. The chromatographic properties of some hydroxamic acids are described and used to characterize these acyl groups.
