Question

Quizplus · Accepted Answer

Disulfide bridges contribute significantly to the strength of keratin protein, particularly in nails. These covalent bonds form between two cysteine residues, stabilizing the protein structure and adding strength. Hydrophobic interactions and salt bridges also contribute to protein stability, but disulfide bridges are the key factor in distinguishing nail keratin from hair keratin in terms of strength.
