Abstract
The enthalpies of solution of glycine, DL-alanine, D-valine, and L-serine in water at 298.15 K were measured on a special ampule calorimeter equipped with an isothermal shell. The enthalpies of hydration of 12 α-amino acids differing in the steric configurations of the side radical were estimated using the measured values and the published data on the heats of solution and sublimation for biologically active substances. The influence of hydrophobicity of the substances on their dissolution and hydration was considered.
