WebA disulfide bond is created by two cysteine residues coming together and creating a sulfur-sulfur linkage. This type of linkage contributes to the tertiary structure of proteins. It can also be seen in quaternary structure between peptide subunits, but tertiary structure is the first level where this force can be observed. WebMetallic bonds are sensitive to oxidation/reduction. Breaking disulfide bonds requires either a strong oxidizing agent, such as performic acid or a strong reducing agent on another disulfide, such as mercaptoethanol or dithiothreitol. Quaternary structures are stabilized by the same forces as tertiary structure and have the same sensitivities.
