ABSTRACT

Apparent molar volumes and partial molar volumes at infinite dilution, 2o, for dipeptides (glycyl glycine, glycyl valine, glycyl leucine, glycyl phenylalanine, and glycyl asparagine) in aqueous sucrose and 2,3-butanediol solutions have been calculated from the measured densities in the temperature range of T = (283.15 to 333.15) K. Side-chain partial molar volumes, 2,tro, and transfer volumes, Vtro, for the dipeptides and side chains from water to aqueous additive environment have been calculated and analyzed in terms of possible solute-water, solute-cosolute, and cosolute-water interactions.
