Abstract
The polysaccharide moiety of the O16 antigen (lipopolysaccharide) cons ists of D-glucopyranose, D-galactofuranose, L-rhamnopyranose, and 2-ac etamido-2-deoxy-D-glucopyranose in the molar ratios 1:1:1:1. It is O-a cetylated with one acetyl group per repeating unit. One- and two-dimen sional NMR spectroscopy of the polysaccharide before and after O-deace tylation showed that the O16 polysaccharide has the structure --> 6)-a lpha-D-Glcp-(1 --> 3)-alpha-L-Rhap-(1 --> 3)-alpha-D-GlcpNAc-(1 --> 2) -beta-D-Galf-(1 --> 2 \ OAc
