Web in aqueous solution, the carboxyl group can lose a proton and amino group can accept a proton, giving rise to a dipolar ion known as zwitter ion. Web the reason amino acids exist largely in their zwitterionic form at biological ph p h (usually around 7) is due to the pka p k a of the constituent groups. Web the two forms of amino acids that your question asks about are called zwitterions (technically iupac says they should be called dipolar ions but the term zwitteron is pervasive). Rch (nh2)co2h ⇌ rcn (n+h3)co− 2 the ratio of the concentrations of the two species in solution is independent of ph. In zwitter ionic form, amino acid show amphoteric behaviour as they react both with acid and bases.
