| 520 | 3 | |a Apparent molar volumes Vϕ and adiabatic compressibilities Kϕ,s of L-glycine, L-alanine, and L-valine in aqueous sucrose solutions ranging from pure water to 25mass% of sucrose have been determined at 298.15K from precise density and sound speed measurements. Partial molar volumes Vϕ0 and partial molar adiabatic compressibilities Kϕ,s0 of these amino acids at infinite dilution were evaluated. These values are required for calculating hydration number nH of amino acids. Transfer volumes ΔVϕ0 and transfer adiabatic compressibilities ΔKϕ,s0 at infinite dilution from water to aqueous sucrose solutions have been calculated. Transfer parameters have been discussed in terms of solute-cosolute interaction on the basis of a cosphere overlap model. Group contributions for the partial molar volumes and adiabatic compressibilities have been determined from the amino acids. All these results indicate that hydrophilic ionic group interactions are stronger than the hydrophilic-hydrophobic interactions in all the amino acids over the whole concentration range of sucrose solutions and decrease with the increase in size of side chain of amino acids. | |
