✦ Synopsis

The fragments of the rhamnogalacturonan backbone carrying neutral sidechains ("hairy" fragments) of sugar-beet pectins have been subjected to methylation analysis and mild acid treatment. The fragments have similar structures which consist of a rhamnogalacturonan backbone carrying highly branched (1+5)-linked arabinans and linear (1+4)-linked galactans of low d.p. together with (1+3,6)linked galactans in low proportions. Of the feruloyl groups, 50% are esterlinked to the neutral side-chains and are removed together with arabinose or galactose residues.

The actions of ammonium persulfate on (feruloylated) sugar-beet pectins and ferulate have been studied by spectrophotometry, viscometry, 'H-n.m.r. spectroscopy, and gel-permeation chromatography. The reactions followed a pseudo-firstorder law with respect to pectin and ferulate, whereas the order wi
