A new contribution to the determination of the complex equilibria of oxidised glutathione with proton and copper(II) in aqueous solution
Abstract
The stability constants of the complexes formed between copper(II) and oxidised glutathione have previously been determined. In the present work, using identical experimental conditions, we have essentially confirmed the model previously proposed, above pH 5. However, for the range pH 2–5 we support a later model proposed by other workers which questioned the correctness of the earlier one.
