Abstract EN
The interaction of iodine with bovine serum albumin (BSA) in dimethylsulfoxide (DMSO) aqueous solutions was studied by means of fluorescence and UV/Vis absorption spectroscopy methods.
Physicochemical peculiarities of these solutions were revealed.
The results showed that the tri-iodide ion formed in the 1DMSO : 2H2O solution caused the fluorescence quenching of BSA.
The modified Stern-Volmer quenching constant Ka and corresponding thermodynamic parameters, the free energy change (ΔG), enthalpy change (ΔH), and entropy change (ΔS), at different temperatures (293, 298, and 303 K) were calculated, which indicated that the hydrophobic and electrostatic interactions were the predominant operating forces.
The binding locality distance r between BSA and tri-iodide ion at different temperatures was determined based on Förster nonradiation fluorescence energy transfer theory.
