9. Protein folding. Christian Anfinsen's experiments led to fundamental insights into how and why proteins fold into their specific three-dimensional structures. A) Summarize the fundamental principles of protein folding that were discovered. What were the main conclusions? Question 9 (continued) B) Protein folding is thermodynamically spontaneous ($$\Delta G < 0$$). Think about the parameters of the Gibbs equation ($$\Delta G = \Delta H - T\Delta S$$). Provide a molecular interpretation of how the process of protein folding alters the parameters of $$\Delta H$$ and $$\Delta S$$. Account for the following: (1) How the conformation of the polypeptide changes $$\Delta H$$ and $$\Delta S$$. (2) How the burial of non-polar side chains affects $$\Delta H$$ and $$\Delta S$$. (3) How the number of disulfide bonds would affect $$\Delta H$$ and $$\Delta S$$. Suppose that ribonuclease had only four cysteines instead of eight.
