Zwitterion - an overview ScienceDirect Topics

WebAn amino acid has this ability because at a certain pH value (different for each amino acid) nearly all the amino acid molecules exist as zwitterions. If acid is added to a solution containing the zwitterion, the carboxylate group captures a hydrogen (H +) ion, and the amino acid becomes positively charged. WebA zwitterion has a negative carboxylate ion and ammonium ion. The pH at which the concentration of the zwitterion predominates is the isoionic point. For neutral amino acids, the isoionic point lies halfway between the p Kα values of the carboxylic acid group and the ammonium group. See Table 27.1.
