strong covalent links between sulfur atoms in proteins
Disulfide bonds, also known as S-S bonds, are strong covalent bonds formed between two sulfur atoms, typically within the amino acid cysteine. These bonds play a crucial role in stabilizing the three-dimensional structure of proteins, including keratin in hair, by linking different parts of the protein chain. In hair, disulfide bonds contribute to its strength and elasticity, and their alteration can affect hair texture and resilience.
