Studies on the partial structure of the O-antigen of Vibrio cholera, Inaba 569 B

Five oligosaccharides were isolated in pure state from the lipopolysaccharide of Vibrio cholera, Inaba 569 B, the their structures were elucidated. More-detailed information regarding the partial structure of the lipopolysaccharide, containing glucose, mannose, glucuronic acid, 2-amino-2-deoxyglucose, D-glycero-L-mannoheptose, and D-glycero-L-gluco-heptose, was obtained through Smith degradation, chromium trioxide oxidation, and graded hydrolysis studies of the lipopolysaccharide and its derived products.
