Classify each amino acid according to the electrical charge of its side chain at a pHpH of 2.00.2.00. Recall that the pKapKa values of the Asp, His, and Lys side chains are 3.65, 6.00, and 10.53,3.65, 6.00, and 10.53, respectively. It may help to review the structures of these three amino acids before answering this question.
