摘要：

The structure of the O-antigen from Vibrio cholerae O:2 has been investigated, mainly by methylation analysis, specific degradations, and n.m.r. spectroscopy, and concluded to involve the trisaccharide repeating-unit -> 4)-beta-D-QuipNAc-(1 -> 4)-Sugp-(2 -> 4)-beta-D-Galp-(1 ->, in which QuiNAc is 2-acetamido-2,6-dideoxyglucose and Sug is tentatively assigned as 5-acetamidino-7-acetamido-3,5,7,9-tetradeoxy-L-glycero-beta-L-manno-nonulosonit acid.The acetamidino group is basic and, consequently, the polysaccharide is neutral.When this group is transformed into an N-acetyl group, by treatment with aqueous triethylamine, the polysaccharide becomes acidic.
