In order to obtain an improved understanding of the complexing properties of cyclopeptides involved in biological processes, the interaction of zinc(II) with cyclo(L-histidyl-L-histidyl) was studied by potentiometric and calorimetric techniques in aqueous solution.Comparison between the thermodynamic parameters of the complexes formed with those for analogous species formed with cyclo(glycyl-L-histidyl) allowed evidence to be obtained for the formation of chelate rings of unusual size.The thermodynamic quantities associated with copper(II) complex formation with cyclo(-Gly-His-) were determined.The role of the different stereochemical requirements of copper(II) and zinc(II) in the formation of large chelate rings was assessed by means of previously reported data concerning the copper(II)-cyclo(-His-His-) complexes.
