The most important contribution to the stability of a protein's conformation appears to be the

Options

A. entropy increase from the decrease in ordered water molecules forming a solvent shell around it
B. maximum entropy increase from ionic interactions between the ionized amino acids in a protein
C. sum of free ebnergies of formation of many weak interactions among the hundreds of amino acids in a protein
D. sum of free energies of formation of many weak interactions between its polar amino acids and surrounding water

Answer

C

Explanation

Stability of a proteins depends on free energies of interactions between amino acids.
