Solution densities and speeds of sound of tripeptide (gly(gly)(2)) in aqueous and aqueous glucose solutions have been determined at temperatures: 288.15, 293.15, 298.15, 303.15 and 308.15 K. These solution densities and speeds of sound were used to calculate apparent molar volume at infinite dilution (V-phi(0)) transfer partial molar volume (Delta V-tr(phi)0) apparent molar adiabatic compressibility at infinite dilution (K-phi,S(0)), and its transfer values (Delta K-tr(phi,S)0), at infinite dilution. These parameters have been discussed in terms of solute-solvent interactions. We have also attempted to examine the temperature and concentration dependence of such interactions. Contributions of peptide group (-CONH-) to V-phi(0) and K-phi,S(0) in aqueous solution at 298.15 K are also estimated by comparing with the data in the literature and of alpha,omega-amino acids. Also group contributions to transfer volumes at temperatures: 288.15, 298.15 and 308.15 K from water to aqueous glucose solutions have also calculated. (C) 2010 Elsevier B.V. All rights reserved.
