Entropy of protein folding
WebJan 19, 2024 · The increase in the entropy of water is the driving force of the hydrophobic effect (ΔSwater > 0). Note that as a protein folds, the polypeptide chain loses entropy as it adopts a single conformation but this decrease in entropy is often more than offset by the concomitant gain in the entropy of water molecules as the folded structure buries ... WebProtein folding must be thermodynamically favorable within a cell in order for it to be a spontaneous reaction. Since it is known that protein folding is a spontaneous reaction, then it must assume a negative Gibbs free energy value. Gibbs free energy in protein folding is directly related to enthalpy and entropy.
