The zwitter ion has
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. In chemistry, a zwitterion , also called an inner salt or dipolar ion, is a molecule that contains an equal number of positively- and negatively-charged functional groups. With amino acids, for example, in solution a chemical equilibrium will be established between the "parent" molecule and the zwitterion.
