WebNov 8, 2014 · 1. At pH 7.4 a carboxyl group is mostly present as COO -, while an amino group is present as NH 3+. So when a molecule has both groups, such as an amino acid, the molecule as a whole is neutral. As it is a Zwitterion (equal + and - charges) the hydrogen can also flip flop between amino and carboxyl group. WebWhen pH equals 9, only half of the amino acids will exist as zwitterions — the other half will have assumed an anionic form, where even the α-amino group is deprotonated. Eventually, when pH rises high enough, all the amino acids in solution will exist in their fully deprotonated, anionic form.

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. WebZwitterions have the isoelectric point property that helps measure the pH value of the ion or substance when the charges on them are neutral. It is represented as pI, pH (I), and IEP.
