What is the meaning of a disulfide bond. What does disulfide mean. Disulfide bond is a single covalent bond derived from the coupling of thiol SH groups. Disulfide bonds within gluten proteins play a key role in the breadmaking performance of wheat flour.

Disulfide bonds play a critical role in maintaining the peptide conformation and biological activity of these molecules. The linkage is also called as an S-S-bond or disulfide bridge. Disulfide bonds are a second post-translational modification that is unique to proteins synthesized in the ER.

Disulfide reduction by the use of disulfide interchange can be performed using thiol-containing compounds such as TCEP DTT 2-mercaptoethanol or 2-mercaptoethylamine Chapter 2 Section 41The formation of free sulfhydryls from a disulfide group occurs in two stages. The covalent bond between sulfur atoms that binds two peptide chains or different parts of one peptide chain and is a structural determinant in many protein molecules. In chemistry a disulfide bond is a covalent bond usually derived by the coupling of two thiol groups.
