"WebAbstract. During biosynthesis, a globular protein folds into a tight particle with an interior core that is shielded from the surrounding solvent. The hydrophobic effect is thought to play a key role in mediating this process: nonpolar residues expelled from water engender a molecular interior where they can be buried.

WebA study of how hydrophobicity (HY) drives protein folding reveals two kinds of HY: intrinsic (proportional to surface area) and extrinsic (augmented by hydration shells). The Nozaki–Tanford method of measuring HY has been modified to use gaseous solutes. Hydration shells on alkanes explain the unusual HY of alkanes. WebA widespread practice is to use free energies of transfer between organic solvents and water (delta G0transfer to define hydrophobicity scales for the amino acid side chains. A comparison of four delta G0transfer scales reveals that the values for hydrogen-bonding side chains are highly dependent on …
