The use of 1Hâ??31P GHMBC and covariance NMR to unambiguously determine phosphate ester linkages in complex polysaccharide mixtures
Abstract Poly- and oligo-saccharides are commonly employed as antigens in many vaccines. These antigens contain phosphoester structural elements that are crucial to the antigenicity, and hence the effectiveness of the vaccine. Nuclear Magnetic Resonance (NMR) is a powerful tool for the site-specific identification of phosphoesters in saccharides. We describe here two advances in the characterization of phosphoesters in saccharides: (1) the use of 1Hâ??31P...
