High resolution 13C-n.m.r. spectroscopy of 'mixed linkage' xylans
Three xylan fractions, obtained by stepwise precipitation with ethanol, were analysed by 75-MHz 13C-n.m.r. spectroscopy. Diad frequencies, determined from the C-2 resonances, show that the (1 → 3)-linkages are interspersed throughout the chain rather than grouped contiguously. This type of distribut...

| 520 | 3 | |a Three xylan fractions, obtained by stepwise precipitation with ethanol, were analysed by 75-MHz 13C-n.m.r. spectroscopy. Diad frequencies, determined from the C-2 resonances, show that the (1 → 3)-linkages are interspersed throughout the chain rather than grouped contiguously. This type of distribution is in agreement with a random coil conformation and with the constancy of the optical rotation in solvents of different ionic strength and chaotropic power. These diad frequencies were compared with the theoretical values calculated for a random distribution from the ratio of (1 → 4)-:(1 → 3)-linkages in the 1H-n.m.r. spectra, and from the methylation analysis for one of the fractions. © 1992 Butterworth-Heinemann Limited. |l eng | |
