10. In a protein, the amino acid pairs below are near each other in the tertiary structure. For each pair briefly
describe (10 words or less per pair) what kind of interaction is likely to occur at pH 7.4. If no interaction is likely,
clearly state so.
a. Cys-Arg
b. Pro-Asp
C. Ser-Phe
d. His-Gln
11. You are using ion-exchange chromatography to separate the amino acids F, T, K and D. Using a cation-exchange
polystyrene resin (the resin has a charged group attached-think about what the charge is-and the resin itself
is hydrophobic) and a buffer at pH 7.5, predict the order of elution of these amino acids as the salt concentration
is raised.
