The structure of the O-antigenic side chain of the lipopolysaccharide of Vibrio cholerae 569B (Inaba).
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.
