Dynamics Approach to Protein Hydration

Internal water plays a role in the structure of proteins. It is difficult to detect and measure these waters by means of X-rays and therefore statistical thermodynamic 

An example of this kind of calculation, due to Wade et al., is the computation of the hydration of two internal cavities in a sulfate-binding protein. The results are given in Table 2.30. The main difference between having a dry cavity and having a wet one is the hydration bond energy.
