Abstract

Cu(II)-glycylglycine chelates with cysteine forming red-purple transient. A transient which is formed immediately upon mixing the reactants is a ternary Cu(II) complex. Another transient is a binary Cu(II) complex of cysteine produced successively from the ternary complex. Spectrophotometric properties of those transients are discussed.
