Questions & Step-by-Step Solutions

What type of bond forms between cysteine residues in proteins?
  • Step 1: Identify the amino acid cysteine, which is a building block of proteins.
  • Step 2: Understand that cysteine contains a sulfur atom in its side chain.
  • Step 3: Recognize that when two cysteine residues come close together, their sulfur atoms can interact.
  • Step 4: Learn that this interaction forms a special type of bond called a disulfide bond.
  • Step 5: Realize that disulfide bonds help stabilize the overall structure of the protein.
