Revisiting the carboxylic acid dimers in aqueous solutions: interplay of hydrogen bonding, hydrophobic interactions, and entropydhydrogen bonds

Article Abstract:

Classical force field and free energy analysis have shown that both hydrogen bonding and hydrophobic interactions are important for dimerization of carboxylic acids. The fundamental statistical thermodynamics formalism is revisited and clarified for calculating absolute binding constants, external entropy and solvation entropy changes.

What can really be learned from dielectric spectroscopy of protein solutions? A case study of ribonuclease A

Article Abstract:

A dielectric relaxation study of aqueous solutions of ribonuclease A at 298.15 K is reported as a function of protein concentration between 0.5 and 6-wt % in the MHz/GHz frequency range. In addition, the roles of intraprotein motions, which may contribute near 500 MHZ (delta 2) are also discussed.
