Question

A newly formed protein usually folds into its native state rapidly even before it is completely built by the ribosome. The free energy for the folding process has at least two key components-one enthalpic and the other entropic. Which of the following is/are part of the enthalpic changes that accompany protein folding? OA. Hydroxylation of prolines and lysines. B. Formation of a salt bridge between a lysine side chain and an aspartic acid side chain within the interior of the folded protein. OC. Deprotonation of a histidine side chain involved in a salt bridge to its neutral form. OD. Expulsion of water from the folded structure's interior.

Answer 1

B.
