The interactions between glutathione disulfide, GSSG, the redox partner and dimer of the intracellular detoxification agent glutathione, GSH, and hexavalent uranium, U(VI), were extensively studied by solution NMR (in D2O), complemented by time-resolved laser-induced fluorescence and IR spectroscopies. As expected

3-(Trimethylsilyl)propanesulfonic acid (TMSPS) is used as a water-soluble NMR frequency marker. It has its major resonance at 0.00 ppm relative to trimethylsilane, and smaller resonances at 0.62, 1.77 and 2.85 ppm. Its toxicity was tested by exposing contracted porcine carotid
