Amino acids behave like salts rather than simple amines or carboxylic acids. This behavior is due to the presence of both acidic (COOH) and basic (-NH_(2) group in the same molecule. In aqueous solution, the carboxyl group can lose a proton and amino group can accept a proton, giving rise to a dipolar lon known as Zwitter ion.Which of the following is the major species in a solution of lysine at pH = 3.5?
