    • Compared to say, a covalent bond, a hydrogen bond is approximately one tenth of that strength.
    • Each hydrogen bond between molecules is much weaker than the covalent bonds holding the atoms together within the molecule.
    • Breaking a single hydrogen bond may impair the stability of a protein.
    • This is consistent with a structure that has lost the intramolecular hydrogen bond.
