ABSTRACT

The speeds of sound measurements are carried out for investigating the interactions of glycine, l-alanine, and l-valine in (0.2,0.4,0.6, and 0.8) mol*kg -1 (0.2,0.4,0.6, and 0.8) mol*kg-1 solutions of triammonium citrate (TAC) at T=(288.15,298.15,308.15, and 318.15) K T=(288.15,298.15,308.15, and 318.15) K . The speeds of sound values were used to determine apparent molar isentropic compression, partial molar isentropic compression (? 0 ,s ) ,s0) , hydration number (n H ) nH) , standard partial molar isentropic compression of transfer (? 0 ,S ) ,S0) . The pair and triplet interaction coefficients have also been calculated. The results have been discussed in terms of prevailing interactions between amino acids and TAC solutions.
