Abstrakt: A recent report has shown the active site of the beta subunit of mitochondrial ATP synthase is probably the site of action of Cr(III) action, independent of the insulin signaling pathway. This works appears to answer an important question about the mode of action of Cr(III) at a molecular level when supplied in supra-nutritional levels to rodents. However, as with any good research, the research also raises several questions. The relationship between this study and the results of rodent studies of chromium supplementation and between this study and the current understanding the chromium(III) transport and detoxification system are put into perspective.
