Hydrophobic effects

WebA Hydrophobic Effect. The major driving force in protein folding is the hydrophobic effect. This is the tendency for hydrophobic molecules to isolate themselves from contact with water. As a consequence during protein folding the hydrophobic side chains become buried in the interior of the protein. What are hydrophobic protein interactions?
