(a)  Hydrophobic interactions:  These are nonpolar side chains of amino acids that tend to associate to form hydrophobic clusters usually away from the protein surface.

(b)  Hydrogen bonds: Such bonds may occur between the components of the peptide bond, the side chains, or a combination of the two. They are responsible for helical and pleated sheet structures of proteins.

(c) Disulfide bridges: Such bonds are formed between two cysteine side chains and, because of their covalent nature, represent relatively strong attractive forces between different (sometimes distant) regions of proteins.
