Densities ρ and viscosities η for several concentrations of amino acids (Serine, Cysteine and Threonine) at different temperatures (298.15, 303.15 and 308.15K) have been measured. On the basis of these data, the apparent molal volumes , partial molal volumes at infinite dilution , slope Sv , Gibbs free energy of activation for viscous flow of solution ∆G1,2 and Jones – Dole B-coefficients were calculated the nature of solute-solvent and solute-solute interactions have been discussed in terms of the values of , , Sv and B-coefficents.
