Complex formation constant of ferric ion with Gly, Pro-Hyp and Gly-Pro-Hyp

The interaction in double and ternary systems containing Fe3+ ions and biologically active substances – succinic acid and/or one of the amino acids (glycine, glutamic acid, aspartic acid) has been studied by spectrophotometry, photometry, pH-metry and solubility techniques. The composition and stability constants of homo- and mixed-ligand complexes were determined at ionic strength I = 0.3; iron(III) succinate with the composition of Fe2Suc3 ∙ 3H2O was isolated, its solubility constant was determined according to solubility data, lgKS = –27.74 ± 0.12. The redox process in the iron(III)–succinate-anion system was noted over time.
