High resolution 13C-N.M.R. spectroscopy of legume-seed galactomannans
Five galactomannans obtained by aqueous extraction at different temperatures from the endosperm of the seed of Gleditsia triacanthos, and having different Gal:Man ratios, were submitted to a preliminary degradation, and the products analyzed by high resolution 13C-n.m.r. spectroscopy. In these spect...

| 520 | 3 | |a Five galactomannans obtained by aqueous extraction at different temperatures from the endosperm of the seed of Gleditsia triacanthos, and having different Gal:Man ratios, were submitted to a preliminary degradation, and the products analyzed by high resolution 13C-n.m.r. spectroscopy. In these spectra all carbon atoms yield several lines. C-6 (substituted Man) shows, for the first time, a clear splitting, which is explained by considering that this carbon atom is sensitive to whether or not its neighbors are branched; this provides a basis for determining the next-nearest-neighbor probabilities in the galactomannans ("triad frequencies"). Although diad frequencies are roughly consistent with a random arrangement, the values obtained for the triad frequencies indicate a more complex kind of arrangement of the lateral chains. © 1986. |l eng | |
