During the folding of a globular protein into its tertiary structure, which bond provides the strongest covalent reinforcement to the three-dimensional conformation?
Q1. During the folding of a globular protein into its tertiary structure, which bond provides the strongest covalent reinforcement to the three-dimensional conformation?
Answer: Disulfide bridges
Explanation: Disulfide bridges are strong covalent bonds between cysteine residues, providing more stability than weaker hydrogen or ionic bonds in tertiary folding.
