The structure of the O-specific polysaccharide chain from Citrobacter O23-lipopolysaccharide.
The structure of Citrobacter O23-specific polysaccharide has been shown by sugar and methylation analyses of the native and chemically degraded polysaccharide and by 1H- and 13C-n.m.r. spectroscopy to consist of the tetrasaccharide repeating-units: ----4)-alpha-D-Man-(1----2)-alpha-D-Man-(1----2)-beta-D-Man- (1----3)-alpha-D-GalNAc-(1----, 80% of which are substituted by O-acetyl groups.
