Water at apolar surfaces has rather distinctive thermodynamic properties, in particular an unusually low entropy and high heat capacity. Displacement of water from apolar surfaces to bulk during protein folding and ligand binding dominates observed heat-capacity changes of the whole system. Consequently, apolar surface hydration has received much more attention than that of polar surfaces. Water... 

One can define the water of hydration as all water that is measurably affected by the protein or that affects the protein. Measurement of the system heat capacity as a function of composition gives a particularly credible estimate of the water of hydration. Heat capacity changes are found for solvation of all elements of the protein surface, in particular nonpolar groups. 

Hydration of lanthanide complexes. X-ray diffraction studies of the solid complexes of KLn(EDTA)(H20),c showed the number of water molecules in the coordination sphere to be three for the lighter lanthanides and two for the heavier ones for total coordination numbers of nine and eight, respectively, since EDTA is hexadentate (Hoard et al. 1967). Ots (1973) measured a maximum at europium for the heat capacity change AC° for the formation of lanthanide-EDTA complexes. This maximum was taken as a strong evidence for hydration equilibrium between the complexed species,...
