You learned that a polypeptide in solution usually folds spontaneously into its proper three-dimensional shape. the driving force for this folding is the tendency to achieve the most favored thermodynamic conformation. a folded polypeptide can be induced to unfold (i. e., will undergo denaturation) if the solution is heated or made acidic or alkaline. the denatured polypeptide is a random structure, with many possible conformations.
