WebApr 10, 2024 · 2.1.2 Disulfide Bond. A disulfide bond (S–S) is a type of covalent bond and occurs between two sulfur atoms. The average dissociation energy of S–S is approximately 240 kJ mol −1, which is lower than carbon–carbon (C–C) single covalent bond (346 kJ mol −1) [77, 78].Therefore, S–S are very weak short bonds and require less energy to form.
