Which of the following best explains the role of hydrogen bonds in protein structure?
- AHydrogen bonds form within amino acids to join the carboxyl group to the amino group.
- BHydrogen bonds form between amino acids to hold them in a polypeptide chain.
- CHydrogen bonds form between amino acids and water molecules to contribute to the quaternary structure of the protein.
- DHydrogen bonds form between amino acids to hold the protein in its secondary-structure shape (e.g., alpha-helix).
