%X Viscosities of L-leucine/L-glutamine/L-alanine/glycylglycine + 0.512 mol&middot;kg<sup>-1</sup> aqueous K<sub>2</sub>SO<sub>4</sub>/0.512mol&middot;kg<sup>-1</sup> aqueous KNO<sub>3</sub> solutions have been measured as a function of molal concentration of amino acids/peptides at different temperatures (298.15, 303.15, 308.15, 313.15, 318.15 and 323.15) K. Using the viscosity values of the studied systems the viscosity <i>B</i>-coefficients and activation parameters: <img src=\"Edit_d19c8ba8-d223-440f-9ff2-09db201ce48f.png\" width=\"25\" height=\"15\" alt=\"\" />, <img src=\"Edit_b78e5f05-7d27-4b96-bd02-6ef8a0e41fd1.png\" width=\"25\" height=\"15\" alt=\"\" />, <img src=\"Edit_73efd466-9408-4854-8439-ecb08c12ee4f.png\" width=\"25\" height=\"15\" alt=\"\" />and <img src=\"Edit_cab263a9-724b-4223-b373-e6fbb4f8a413.png\" width=\"25\" height=\"15\" alt=\"\" /> have been computed. The <i>B</i>-coefficient is a quantity of active solvodynamic measurements of solvated ion and also is overseen through magnitude and form properties of solute, and the basic effects made by means of the solute-solvent functioning. The experimental and computed parameters have been discussed in terms of ion-ion, hydrophilicion and hydrophobicion interactions operative in the systems.
