Relation of conformational entropy and protein folding

WebThe entropic penalty is the fact that entropy for going from the disordered unfolded state to ordered folded state is a huge decrease in entropy even in comparison to the release of water molecules into the solution when the hydrophobic proteins release into the solution (out of the clathrate cage).

The internal energy of an ideal gas depends only on its temperature, and not on the volume of its containing box, so it is not an energy effect that tends to increase the volume of the box as gas pressure does. This implies that the pressure of an ideal gas has an entropic origin. What is the origin of such an entropic force? The most general answer is that … The hydrophobic effect is the observed tendency of nonpolar substances to aggregate in an aqueous solution and exclude water molecules. The word hydrophobic literally means "water-fearing", and it describes the segregation of water and nonpolar substances, which maximizes hydrogen bonding between molecules of water and minimizes the area of contact between water and non…
