The amino acid L-histidine (L-His) has a side chain with a functional group called an imidazole, which in its protonated form has a pKa of 6.9. Draw its four different ionization states in water at the pH values indicated. Write the total charge on the molecule in the box at the bottom. pH = 8 is done for you. pH = 0 pH = 4 pH = 8 pH =12 +H3N. N= 0 NH
