title: The xylose-rich pectins from pea hulls.
abstract: The hot acid extract of pea hull, HSP, was rich in galacturonic acid, arabinose and xylose. It was fractionated by copper precipitation followed by ion-exchange chromatography. The copper-soluble fraction represented 26% of HSP and was mostly composed of an arabinan with a low degree of branching, some heteroxylans and a glucan, probably starch. The copper-precipitate (74% of HSP) contained pectins and some residual arabinan, xylan, glucan and mannan. One of the pectic fractions was rich in terminal xylose and fucose; it could be partially degraded by endo-polygalacturonase but not by endo-xylanase and seemed to contain xylogalacturonans.
