Abstract | The study of metal complexes with physiologically active ligands has both scientific and practical implications. In this work, we investigated the formation of binary and ternary complexes involving metal ions such as Cu (II), Ni (II), Co (II) and Zn (II), specifically with two physiologically relevant ligands: glutamine (A) as the major ligand and thymine (B) as the secondary ligand. To evaluate the complexation behaviour of these species in aqueous environments, a potentiometric method was used at 37±1°C and ionic strength, I = 0.1 M NaNO3. The complexes' stability constants were found using Irving and Rossetti's approach, which was subsequently improved using the SCOGS computer software. The findings demonstrated that in most cases, mixed-ligand ternary complexes formed concurrently, often at higher pH levels, resulting in a steady decline in binary complex concentrations for the corresponding metal ions. The species distribution curve displays the binary and ternary species that were investigated. The ligands' protonation constants and the stability constants of their complexes with metal ions followed the order of MA, MB, and MAB. |
