Abstract

A short introduction to the notation of microscopic and macroscopic acidity constants of amino acids is given. The historical pathways are discussed, which led to the contemporary understanding of the acid base reactions of amino acids and their zwitterionic nature in solutions at the isoelectric point. This text is for undergraduate studies of analytical chemistry and biochemistry.
