Development of a 1H NMR structural-reporter-group concept for the primary structural characterisation of α- d-glucans

A 1H NMR structural-reporter-group concept, based on the analysis of a series of linear α- d-glucopyranose di- and trisaccharide structures, has been formulated to function as a tool in the structural analysis of bacterial α- d-glucans. An NMR study of proton chemical shift patterns of known linear...

Description
Summary:A 1H NMR structural-reporter-group concept, based on the analysis of a series of linear α- d-glucopyranose di- and trisaccharide structures, has been formulated to function as a tool in the structural analysis of bacterial α- d-glucans. An NMR study of proton chemical shift patterns of known linear α- d-glucopyranose di- and trisaccharide structures was carried out. Chemical shift patterns for (α1→2)-, (α1→3)-, (α1→4)- and (α1→6)-linked d-glucose residues were analysed and compared to literature data. Using these data, a 1H NMR structural-reporter-group concept was formulated to function as a tool in the structural analysis of α- d-glucans.
