Consider the following amino acids. Based off their side chains
4. Consider the following amino acids. Based off their side chains, which would you suspect to be the most prevalent in the hydrophobic core of a protein. Justify your response. 5. Are the hydrophobic interactions caused by the repulsion between water and nonpolar molecules? Explain in your own words what happens to the water structure near hydrophobic molecule? Is water special?
