WebThe (neutral) zwitterion is the usual form amino acids exist in solution. Depending on the pH, there are two other forms, an anion and a cation: This parallels the behavior of a diprotic acid: with two dissociation steps controlled by two acidity constants K 1 and K 2. Tautomerism of amino acids follows this stoichiometry: RCH(NH2)CO2H ⇌ RCN(N H3)CO−2 The ratio of the concentrations of the two species in solution is independent of pH.
