Sažetak
The second equilibrium constants for the formation of copper bis-chelates with naturally occurring amino acids were correlated with topological indices. The constants correspodn to chelates with the same amino acid (CuAA), five to bis-complexes of atomatic amino acids, five to mixed complexes with glycine and four to mixed complexes with alanine (altogether 27 complex). Multiple regression of log K2 vs toplogical indices of amino acids which constitute the complex gave similar results irrespectively of the topological indices used. Correlation varied from R=0.696 to 0.746 for the formulas of amino acids and up to R=0.756 for the formulas of ML and ML2 complexes.
