Relatively long-lived chromium(V) species are produced by the action of glutathione on carcinogenic chromium(VI)
Abstract
X-Band EPR studies on aqueous solutions of potassium dichromate and gamma-L-glutamyl-L-cysteinylglycine (reduced glutathione) at pH 6-8 have shown the formation of several relatively long-lived chromium(V) species. The major species formed at high glutathione:Cr(VI) ratios is characterised by an EPR band at g = 1.995, but the dominant complex at equimolar ratios produces a signal at g = 1.985.
