Metabolism and Glucose Tolerance Factor Activity of Synthetic Amino acid Abstract The Glucose Tolerance Factor (GTF), a chromium containing complex, has been isolated from yeast by Schwartz & Mertz. This was instrumental in the recognition of the role of trivalent chromium, complexed to amino acids, in regulation of glucose metabolism and of active GTF as a potential antidiabetic agent. We repo...

In the presented paper, the influence of the molecular weight and the type of polyamino acid functional groups on the electrokinetic properties and the stability of chromium (III) oxide suspension were examined. Analysis of the data obtained from the adsorption, potentiometric titration, zeta potential, and stability measurements allows to propose stabilization or destabilization mechanism of t...

The objective of this paper is to demonstrate an approach to characterize the spatial variability in ambient air concentrations using mobile platform measurements. This approach may be useful for air toxics assessments in Environmental Justice applications, epidemiological studies, and environmental health risk assessments. In this study, we developed and applied a method to characterize air to...

The first systematic study of the CrðH2OÞ n ðnZ1K4Þ series of clusters is herein presented at the level of the unrestricted DFT B3LYP level in conjunction with electron core potential basis sets. The present structures are relevant for laser-induced and laser-ablation syntheses of chromium compounds, and also for fundamental spectroscopy studies of metal-bearing species in the gas phase. Calcul...

176 chromium-exposed and 30 control subjects were selected for this study. Blood samples (3 ml) were collected for the estimation of chromium. The data on chromium concentration indicated a significant higher level of chromium in the blood of the exposed workers as compared to the control. There was no significant correlation between the mean blood and environmental chromium level. This study s...

Analysis of soil from a specific site in New Jersey indicated a low level of sodium and chromium present as a calcium compound. Chromium was then administered orally to young, mature male rats at a level of 240 micrograms/kg for 14 days as chromium-contaminated soil, as CaCrO4, and as an equimolar mixture of the soil and calcium salts for 14 days. The rats were sacrificed 24 hr after the last d...

Chromium is nephrotoxic in experimental animals. In subjects with acute chromium intoxication acute nephritis has been reported and renal function has been affected in chromium exposed workers with a high urinary chromium concentration. Chronic kidney disease after long term occupational exposure to chromium has, however, not been reported previously. A case report is presented concerning a 48 ...

Before you make the junkyard your new jaunt, it's a good idea to take a look at some of the research on the impact of chromium supplements on metabolism and weight loss. One type of chromium (more on those in a bit), trivalent chromium, has been shown to enhance the effectiveness of insulin, a hormone that helps metabolize and store carbohydrates, fat, and proteins in the body. While researcher...
