Disulfide bonds are covalent bonds formed between two cysteine residues through oxidation of their sulfhydryl (-SH) groups. These bonds provide strong structural stability to proteins, particularly extracellular proteins like insulin and keratin. Key Points: • Disulfide bonds form between two cysteine residues (-SH → -S-S-). • Stronger than hydrogen bonds and ionic interactions. • Play a crucial role in protein folding and stability. • Found in extracellular and secretory proteins.
