title: Structure of the O-specific polysaccharide of the O22-antigen (LPS) from Escherichia coli O22:K13.
abstract: The polysaccharide moiety of the O22-antigen (lipopolysaccharide, LPS) consists of 2-acetamido-2-deoxy-D-galactose, D-glucuronic acid, D-glucose, and D-galactose in the molar ratios 2:1:1:1. Methylation analysis as well as 1D and 2D NMR spectroscopy showed that the O22 polysaccharide has the primary structure [formula: see text]
