Development of a 1H NMR structural-reporter-group concept for the primary structural characterisation of alpha-D-glucans
Abstract
An NMR study of proton chemical shift patterns of known linear alpha-D-glucopyranose di- and trisaccharide structures was carried out. Chemical shift patterns for (alpha1-->2)-, (alpha1-->3)-, (alpha1-->4)- and (alpha1-->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 alpha-D-glucans.
