Questions & Step-by-Step Solutions

What is the role of disulfide bonds in peptides?
  • Step 1: Understand that peptides are small chains of amino acids.
  • Step 2: Know that cysteine is a type of amino acid that can form special bonds.
  • Step 3: Learn that disulfide bonds are formed when two cysteine amino acids come close together.
  • Step 4: Recognize that these disulfide bonds create a strong link between different parts of the peptide.
  • Step 5: Understand that these bonds help keep the shape of the peptide stable, which is important for its function.
