Abstract: | The purified, specific polysaccharide from Vibrio cholera type NAG, NV 384, O-antigen, 2A, 2Bhuman, contains glucose (5.14%), galactose (4.21%), mannose (64.8%), xylose (3.16%), arabinose (1.98%), fucose (1.50%), mannuronic acid (14.3%), phosphate (0.32%), 2-amino-2-deoxy-D-glucose (2.9%), and 2-amino-2-deoxy-D-galactose (1.0%). Various reactions have shown that the material comprises a phosphoric diester-linked polysaccharide containing mainly (1→2)-linked mannopyranose residues that are highly branched with other sugar residues. |
