Protein folding

Protein folding is the physical process by which a protein chain is translated to its native three-dimensional structure, typically a "folded" conformation by which the protein becomes biologically functional. Via an expeditious and reproducible process, a polypeptide folds into its characteristic three-dimensional structure from a random coil. Each protein exists first as an unfolded

The Shape and Structure of Proteins

The folding of a protein chain is, however, further constrained by many different sets of weak noncovalent bonds that form between one part of the chain and another. These involve atoms in the polypeptide backbone, as well as atoms in the amino acid side chains. The weak bonds are of three types: hydrogen bonds, ionic bonds, and van der Waals attractions, as explained in Chapter 2 (see p. 57).
