WebFeb 6, 2024 · In the “golf course model”, folding takes an astronomically long time because protein has to lose all its entropy before starting to gain the negative energy of interactions. For a faster folding, it is necessary that the gain of the interaction energy nearly immediately compensates the loss of conformational entropy [ 56 ].
