| Abstract: | Interaction of Ni (II) with purine nucleotides (5'-guanosine monophosphate and 5'-inosine monophosphate) and dipeptides (DL-alanyl-alanine and DL-alanyl-phenylalanine) in a 1:1 and 1:1:1 ratios has been investigated by potentiometric pH measurements at 25, 35 and 45°C. The formation constants for various systems are determined by computer program. The stabilization of these complexes is expressed in terms of Δlog K. The stacking interaction associated with nucleotides and dipeptides have been identified with parameters like ΔΔ log K, K1, % of (MLA)st and ΔG0s. The pH profiles of various species are generated in order to identify the stable species. The thermodynamic parameters associated with the above systems are also evaluated for a more comprehensive understanding of these reactions in solution. |
