BACKGROUND L-Arabinose is a non-caloric sugar, which could affect glucose and lipid metabolism and suppress obesity. However, few reports have described the effect of L-arabinose in metabolic syndrome, a combination of medical disorders that increase the risk of diabetes and cardiovascular disease. OBJECTIVE This study was conducted to explore the effects of L-arabinose in rats with metabolic...

A glucose, xylose and arabinose utilizing Zymomonas mobilis strain was constructed by incorporating arabinose catabolic pathway genes, araBAD encoding L-ribulokinase, L-arabinose isomerase and L-ribulose-5-phosphate4-epimerase in a glucose, xylose co-fermenting host, 8b, using a transposition integration approach. Further improvement on this arabinose-capable integrant, 33C was achieved by appl...

Bacterial metabolism of polysaccharides from plant detritus into acids and solvents is an essential component of the terrestrial carbon cycle. Understanding the underlying metabolic pathways can also contribute to improved production of biofuels. Using a metabolomics approach involving liquid chromatography-mass spectrometry, we investigated the metabolism of mixtures of the cellulosic hexose s...

d-Arabinose-5-phosphate and d-sedoheptulose-7-phosphate were found to be substrates, although not inducers, of the hexose phosphate transport system of Salmonella typhimurium. Transport of these two sugar phosphates by wild-type strains required preinduction of the hexose phosphate transport system. A mutant of S. typhimurium constitutive for this system also transported d-arabinose-5-phosphate...

The tiger nut contains different active ingredients like oil, tannins, sterols, saponins, alkaloids, vitamins C and E, minerals, resins. There is a lack of information about carbohydrates content Cyperus esculentus L. Thus, the aim this study was to determine herb tubers. qualitative composition quantitative in tubers ( L.) were determined by using GC/MS method. results analysis showed that hav...

Beet and cane molasses mainly contain mono- di-, tri-saccharides, composed by hexoses, as well pentoses in traces. However, rationing software consider sugars only one entity, with a rate of digestion ∼20% h−1. The aim this initial study was to investigate evaluate the vitro dynamics rates sugar fraction molasses. Three beet three were randomly selected from variety samples collected world-wide...

Uptake of nutrients and organic C was measured once annually between 2000 and 2002 in each of 10 streams within the water-supply source areas for New York City. Nutrients (PO4 3– and NH4 þ) and organic C (glucose and arabinose) were injected into the streams for 1 to 2 h, and uptake lengths were estimated from the longitudinal declines in downstream concentration relative to that of a conservat...

This article evaluates the effect of membrane active channel-forming polyene antibiotic (PA) of levorin and its alkyl derivatives on the muscle performance. The membrane channels of muscle cells are capable to transport ions of potassium, sodium, and calcium. In the period of an intensive muscle exercise, the necessity for organic substrates increases and these channels start to work with the g...

Minicircles are promising vectors for DNA vaccination, gene or cell therapies due to their increased transfection efficacy and transgene expression. The in vivo production of these novel vectors involves the arabinose inducible excision of a parental molecule into a minicircircle and a miniplasmid bacterial backbone. Tight control of recombination is crucial to maximize minicircle yields and pu...

The pentose sugar L-arabinose is one of the most abundant components released by complete hydrolysis of non-starch polysaccharides of feed ingredients of vegetable origin. Two studies were conducted to investigate the apparent ileal digestibility and urinary excretion of L-arabinose at dietary inclusion levels of 50 and 100 g/kg, and 25, 50, 75 and 100 g/kg respectively, in pigs. As a reference...
