title: [Hydration enthalpy characteristics of amino acids in solutions].
abstract: The enthalpies of solvation of 17 amino acids were evaluated by using the sublimation enthalpies of amino acids and the standard enthalpies of their solution in water. An equation was derived, which relates the volume-specific enthalpy of sublimation (deltaH(subl)/V(w)) to the sum of the common bond lengths in molecules (sigman(i)l(i)) of substances examined. The results obtained are interpreted in terms of the effect of hydrophobic and hydrophilic side chain on the interactions between the zwitterions of amino acids and water molecules.
