28. Calculate the overall net charge for the tripeptide leucine-lysine-histidine for pH = 1,3,5,7, 10, and 12 given the following pka values: amino-terminal amino 9.0; carboxy-terminal carboxyl 2.0; side-chain amino 105, and imidazole 6.0. Net charge at pH 1 = Net charge at pH 3 - Net charge at pH 5 = Net charge at pH 7 - Net charge at pH 10 = 6 pts Net charge at pH 12 = 2 pts 29. What is pl for the tripeptide from previous
question? 30. Draw the structure of this tripeptide (leucine-lysine histidine) with the charges as it would exist at pH 5. You do not have to depict the proper stereochemistry in the structure. 3 pts
