520	3		_aThe preferential interactions of proteins with solvent components in concentrated amino acid solutions were measured by high-precision densimetry. Bovine serum al- bumin and lysozyme were preferentially hydrated in all of the amino acids examined, glycine, (Y- and /3-alanine, and betaine, i.e., addition of these amino acids resulted in an unfavorable free energy change. It was shown that, for the former three amino acids, known to have a positive surface tension increment, their perturbation of the surface free energy of water is consistent with their preferential exclusion from the protein surface. In the case of betaine, which does not increase the surface tension of water, preferential exclusion from protein surface must reflect the chemical structure of this cosolvent, which is considerably more hydrophobic than that of the other three amino acids.
