4. Proteases are enzymes that catalyze the hydrolysis of peptide bonds in proteins. The enzyme trypsin is a protease that specifically hydrolyzes only those peptide bonds that are formed by the carboxyl group of basic amino acid residues. Trypsin is present in the small intestine where it functions at an optimum pH of 8. Consider the pentapeptide Phe-His-Val-Lys-Glu. Draw the structures of the products formed from trypsin-catalyzed hydrolysis of this peptide.

For the amino acid alanine, the major species in solution at pH 7 is the zwitterionic form, which has a negatively charged carboxylic acid group and a positively charged amino group. There is a less common neutral form in which neither group is charged. The carboxylic acid group of alanine has a p?apKa of 3.3. The amino group of alanine has a p?apKa of 8.8. Estimate the ratio of the concentration of the neutral amino acid species to the zwitterionic species at pH 7.
