WebThe result is an important test of Kauzmann's 1959 hydration shell mechanism (1, 2) for driving protein folding, which says that hydration shells play a key role in the mechanism. Note that the entropy change upon release of the shells is accompanied by a sizable change in free energy, like Kauzmann's observations in 1959 ( 1 ). WebOct 30, 2011 · Protein folding is a highly complex process by which proteins are folded into their biochemically functional three-dimensional forms. The hydrophobic force is an important driving force behind protein folding. The polar side chains are usually directed towards and interact with water, while the hydrophobic core of the folded protein …
