Disulphide bridges are covalent sulphur-sulphur bonds formed by the oxidation of the thiol groups of two cysteine residues[1]. These types of bonds are most commonly found in the tertiary structure of proteins for further folding, and thus to produce a more specific shape for the ultimate funciton of the protein. Disulphide bonds tend not to be formed in intracellular proteins[2].
