A possible new mechanism for the amplification of insulin receptor tyrosine kinase activity in response to has been identified. The chromium-containing oligopeptide low molecular weight chromium-binding substance (LMWCr) does not effect protein rat adipocytic membrane fragments absence insulin; however, insulin-stimulated is increased up 8-fold by oligopeptide. Using isolated receptor, LMWCr shown bind insulin-activated with a dissociation constant circa 250 pM, resulting increase its...

Chromium(III) tris(picolinate) [Cr(pic)3] is currently a very popular nutritional supplement; however, its safety has recently been questioned, especially with regard to ability act as clastogen. At physiologically relevant concentrations, Cr(pic)3 reduced by biological reductants, including ascorbate and thiols, Cr(II)-containing species. These species are susceptible air oxidation, resulting in the catalytic generation of potent DNA-damaging agent hydroxyl radical. In absence H2O2 can...
