[Computer analysis of polysaccharides with linear repetitive link from 13C-NMR data].
The possibility of computerised analysis of primary structures of polysaccharides on the basis of 13C NMR data and average values of alpha- and beta-effects of glycosidation was evaluated. Theoretical 13C NMR spectra for all possible structures of some linear polysaccharides were calculated by using additive scheme of glycosidation effects. In each case it was found that the structure characterised by the least sum of squared deviations of chemical shifts for the signals in the calculated and experimental spectra corresponds to the sequence and modes of linkages between monosaccharide residues in polysaccharides determined by an independent way.
