Abstract
The structure of an arabinoxyloglucan, separated from the hemicellulosic polysaccharides of the midrib of the leaves of Nicotiana tabacum, was investigated by methylation analyses before and after mild acid hydrolysis, acetolysis and cellulase-degradation. The arabinoxyloglucan consists of L-arabinose, D-xylose and D-glucose in a molar ratio of 13: 33: 54, and has a backbone of β-(1→4)-lniked D-glucopyranosyl residues. Some of the glucopyranosyl residues are attached at the 6 position by single a-D-xylopyranosyl and a-L- arabinofuranosyl-( 1→2)-α-D-xylopyranosyl side chains.This publication has 3 references indexed in Scilit:
