Key Concepts

Protein Folding

Protein folding is the process by which a polypeptide chain folds into its characteristic three-dimensional structure. In globular proteins, the folding process is largely driven by the need to minimize free energy, leading nonpolar (hydrophobic) amino acids to be sequestered in the interior away from the aqueous environment, while polar (hydrophilic) amino acids are positioned on the surface where they can interact with water.

Amino Acid Side Chain Properties

The chemical nature of an amino acid's side chain, specifically its polarity and charge, largely determines where it is located in the protein structure. Nonpolar side chains, which are hydrophobic, tend to be found in the protein’s interior, contributing to a stable core, whereas polar and charged side chains are generally located on the surface to interact with the solvent.

Hydrophobic Effect

The hydrophobic effect is a fundamental driving force in protein folding, resulting from the tendency of water molecules to exclude nonpolar substances. As a consequence, amino acids with hydrophobic side chains aggregate in the interior of the protein, reducing their exposure to water and thereby increasing the overall stability of the structure.
