The kinetics of solubilization of pectic polysaccharides from purified cell walls of Lemna minor (duckweed) and Apium graveolens (celery) by ammonium oxalate at 22° was determined. With cell walls of L. minor , 30 ± 1 (average of three experiments,

Conditions for quantitatively eluting six plant pectic polysaccharides from diethylaminoethyl (DEAE) columns were established. Cations, surprisingly, greatly affected the elution of pectic polysaccharides from these anion-exchange columns. Quantitati

The complete acetylation of apiitol required 9 h when acetic anhydride at 120 degrees was used and sodium acetate was the catalyst. Both apiitol pentaacetate and apiitol tetraacetate were detected before acetylation was complete. When the reaction wa

A particulate enzyme preparation capable of catalyzing the transfer of d -[U-14C]apiose and d -[U-14C]xylose from uridine 5′-(α- d -[U-14C]apio- d -furanosyl pyrophosphate) (UDP[U-14C]Api) and uridine 5′-(α- d -[U-14C]xylopyranosyl pyrophosphat

1. A mild, reproducible extraction procedure, using 0.5% ammonium oxalate, was developed for the isolation of polysaccharides containing d-apiose from the cell wall of Lemna minor. On a dry-weight basis the polysaccharide fractions extracted with amm

A cell-free system was prepared from Lemna minor L. which carried out the synthesis of d-apiose from UDP-d-glucuronic acid. The d-apiose was derived from the glucuronic acid portion of the sugar nucleotide. Paper co-chromatography and periodate oxida
