摘要：

Spectrometry, spectrophotometry, pH-potentiometry, and solubility method have been used to study the reactions proceeding in aqueous solutions containing the "metal of life" ion Cu2+ and biologically active substances, succinic acid and (or) one of the amino acids (aminoacetic, glutamic, and aspartic). The general acid protonation constants, composition, and stability constants of homoligand and mixed ligand copper(II) complexes have been determined at ionic strength I = 0.3; for copper(II) succinate of the composition CuC4H4O4 center dot 2H(2)O, the solubility constant has been found (log K-S = -7.59 +/- 0.06).
