It is observed that as temperature is increased, most protein molecules go from their defined, folded state into a random-coil, denatured state that exposes more hydrophobic surface area than is exposed in the folded state.
a. Given what you have learned so far about ∆H and ∆S, explain why this is reasonable.
b. Sometimes, however, proteins denature as temperature is decreased. How might this be explained?
