Solvent-free melts of unprotected d -ribose and urea generated mainly C1- substituted ribosyl products. The remarkable resolving power of a graphitised-carbon HPLC column allowed products of the reaction formed over a range of heating times and tempe

The instrument-cleaning step is recognised as critical in achieving sterility or high-level disinfection in the medical instrument reprocessing cycle. Proteins in the residual bioburden on instruments after their use present a serious challenge to su

Natural maize starches having a range of amylose contents have been characterised by 13C CP/MAS NMR spectroscopy. Chemical shifts, relative resonance intensities, line-widths and spectral shapes were compared at different moisture contents. At 10% mo

Comparative studies of native maize starches with different amylose contents were carried out using X-ray powder diffraction. The results show a transition of crystalline type from A through C to B, accompanying a decrease in degree of crystallinity

The effects of starch/water ratio, amylose content, degree of phosphorylation, and added KI on water mobility in maize starch-water dispersions were studied by oxygen-17 spin-spin relaxation time measurements over a range of temperatures. The results

The amylose to amylopectin ratios in six maize starch samples of differing amylose contents were measured by enzymatic debranching, followed by high performance size exclusion chromatography (HPSEC). The molecular size of amyloses, estimated by -log

The effects of percentage water content in DMSO/water mixtures on amylose conformation were measured by following changes in specific optical rotation, limiting viscosity number, and 13 C-NMR chemical shifts. The temperature dependence of specific op

The hulls and cotyledons from three Western Australian cultivars (Gungurru, Yorrel and Danja) of Lupinus angustifolius, all of low alkaloid content, were analysed separately for their carbohydrate content and composition. Only minor differences in co
