The hydrolysis of glycylglycine was studied in the presence of Cu(II) and Zn(II) at various pH values between 3.4 and 6.3. Glycine produced by the hydrolysis and remaining glycylglycine were trimethylsilylated and their relative quantities were determined by gas-liquid chromatography. The reaction is promoted by both metal ions. In the presence of Cu(II) the pH-rate profile has a maximum at pH <I>ca.</I> 4.4, whereas in the presence of Zn(II) the rate increases as pH becomes higher. These kinetic results are discussed in terms of the structures of metal(II)-glycylglycine complexes in aqueous solution.
