Thermodynamics of dissociation of glycine in aqueous ethanol and urea solutions

The dissociation enthalpies of glycine in aqueous ethanol and urea solutions have been determined at 298.15 K by LKB-2277 BioActivity Monitor. Combined with the corresponding Gibbs free energies, the dissociation entropies have been calculated. The results have been interpreted with the point of view of structure alteration of the two solvents.
