Textbook Question
Chapter 3, Problem 2S
Hydrogen bonds and hydrophobic interactions each play an important role in stabilizing and organizing biological macromolecules. Consider the four macromolecules discussed in this chapter. Describe how these affect the form and function of each type of macromolecule. Would a disruption in the hydrogen bonds affect form and function? Hydrophobic interactions?

List the four types of non-covalent interactions that are important in providing stability to the three-dimensional structures of macromolecules. Why is it important that these interactions be non-covalent, rather than covalent, bonds?
For each of the following pairs of amino acids, identify the strongest type of intermolecular forces involved when the side chains interact. Explain in terms of the chemical structures of the amino acid side chains. Use the following list: disulfide bridge, hydrogen bonding, hydrophobic interaction, or salt bridge.
