ReviewViscosity B-coefficients and standard partial molar volumes of amino acids, and their roles in interpreting the protein (enzyme) stabilization

Add time:09/01/2019    Source:sciencedirect.com

This review systematically surveys the viscosity B-coefficients and standard partial molar volumes of amino acids at various temperatures as these data are quite important for interpreting the hydration and other properties of peptides and proteins. The effect of organic solutes and various ions on the viscometric and volumetric properties of amino acids has also been discussed in terms of their kosmotropic (‘structure-making’) effects on the hydration of amino acids. The comparison of these effects on the amino acid hydration enables us to have a better understanding of the influence of organic solute and salt on the protein stabilization. In addition, the viscometric and volumetric behaviors of amino acid ions (cations and anions) are also summarized because these ions have recently been incorporated as part of novel ionic liquids, which have wide applications in biocatalysis and protein stabilization.
