Which of the following statements about aromatic amino acids is correct?
(a) All are strongly hydrophilic.
(b) Histidine's ring structure results in its being categorized as aromatic or basic, depending on pH.
(c) On a molar basis, tryptophan absorbs more ultraviolet light than tyrosine.
(d) The major contribution to the characteristic absorption of light at 280 nm by proteins is the phenylalanine
R group.
(e) The presence of a ring structure in its R group determines whether or not an amino acid is aromatic.

(b) Compare the intermolecular forces between phycocyanin and acetone with those between phycocyanin and water. Briefly explain how acetone disrupts the folding in phycocyanin.
(c) Compare the intermolecular forces between phycocyanin and urea with those between phycocyanin and water. Briefly explain how urea disrupts the folding in phycocyanin.

Each ionizable group of an amino acid can exist in one of two states, charged or neutral. The electric charge on the functional group is determined by the relationship between its pKa and the pH of the solution. This relationship is described by the Henderson-Hasselbalch equation.(a) Histidine has three ionizable functional groups. Write the equilibrium equations for its three ionizations and assign the proper pKafor each ionization. Draw the structure of histidine in each ionization state. What is the net charge on the histidine molecule in each ionization state?(b) Draw the structures of the predominant ionization state of histidine at pH 1, 4, 8, and 12. Note that the ionization state can be approximated by treating each ionizable group independently.(c) What is the net charge of histidine at pH 1, 4, 8, and 12? For each pH, will histidine migrate toward the anode (+) or cathode (−) when placed in an electric field?
