Using a quantitative assay for measuring chemotaxis, we tested a variety of sugars and sugar derivatives for their ability to attract Escherichia coli bacteria. The most effective attractants, i.e., those that have thresholds near 10(-5) M or below, are N-acetyl-d-glucosamine, 6-deoxy-d-glucose, d-fructose, d-fucose, 1-d-glycerol-beta-d-galactoside, galactitol, d-galactose, d-glucosamine, d-glu...

Autoxidation, D-Glucose, 2-Methyltetrahydrofuran, a-Hydroxyalkylperoxyl Radicals, y-Irradiation Oxygenated 1 M aqueous solutions of 2-methyltetrahydrofuran (MTHF) or D-glucose were y-irradiated, and G(total peroxide) was determined as a function of dose rate and temperature. Whereas MTHF was oxidized by a chain process, D-glucose was not. The peroxyl radicals derived from D-glucose rapidly elim...

Sepsis is the life-threatening response to infection which can lead to tissue damage, organ failure, and death. In the current study, the effect of orally administered D-glucose on the mortality and the blood glucose level induced by D-Galactosamine (GaLN)/lipopolysaccharide (LPS)-induced sepsis was examined in ICR mice. After various amounts of D-glucose (from 1 to 8 g/kg) were orally fed, sep...

Objective: To study the relationships between serum vitamin D levels and plasma glucose or lipid levels in children and adolescents. Material & Methods: We conducted a prospective study on pediatric patients (age 2-18 years) of Adichunchanagiri Institute of Medical Sciences, BG Nagara from December 2011 to November 2012 with simultaneous measurement of 25-hydroxyvitamin D, fasting plasma glucos...

It has been hypothesized that cancer cells increase glucose metabolism to protect against metabolic fluxes of hydroperoxides via glutathione-dependent peroxidases. 2-Deoxy-D-glucose, inhibits glucose metabolism and has been shown to cause cytotoxicity in cancer cells that is partially mediated by disruptions in thiol metabolism. In the current study, human breast cancer cells were continuously ...

The mechanisms of the requirement of glucose for steroidogenesis were investigated by monitoring the uptake of the glucose analogue 2-deoxy-D-glucose by rat testis and tumour Leydig cells. The characteristics of glucose transport in both of these cell types were found to resemble those of the facilitated-diffusion systems for glucose found in most other mammalian cells. The Leydig cells took up...

A trehalose synthase (TSase) that catalyzes the synthesis of trehalose from D-glucose and alpha-D-glucose 1-phosphate (alpha-D-glucose 1-P) was detected in a basidiomycete, Grifola frondosa. TSase was purified 106-fold to homogeneity with 36% recovery by ammonium sulfate precipitation and several steps of column chromatography. The native enzyme appears to be a dimer since it has apparent molec...

Helicobacter pylori is a gram-negative pathogenic microaerophile with a particular tropism for the mucosal surface of the gastric epithelium. Despite its obligatory microaerophilic character, it can metabolize D-glucose and/or D-galactose in both oxidative and fermentative pathways via a Na(+)-dependent secondary active transport, a glucokinase and enzymes of the pentose phosphate pathway. We h...
