| Abstract: | Formation constants for the interaction of copper(II) with captopril have been measured using (i) histidine and (ii) 2,3-diaminopropionic acid monohydrochloride as competing ligands to prevent redoxing. The main species present in both the binary and ternary experimental systems are reported. Blood plasma models based upon these new formation constants indicate that captopril at high doses may mobilise copper(II) from blood plasma. |
