Question

2. Amino acids are commonly classified as nonpolar or as polar, based on the properties of the side chain residues. Quantification of these properties is important for a variety of protein structure predictions, but they cannot readily be determined from the free amino acids themselves. Why are the properties of the side chains difficult to measure using the free amino acids in aqueous or nonpolar solvents? How might you quantitatively determine hydrophobicity of amino acid side chains? (40 points)
