WebWhat is zwitterion or Zwitterion Definition: Zwitterion can be defined as the molecule which contains both negatively charged ions as well as positively charged ions. Amino acids can exist in dipolar forming the solid state and are termed as Zwitterion. For a compound to be zwitterion it is important to understand the concept of pH. 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.

It has both a basic amine functionality and an acidic carboxylic acid functionality. At a high pH, the acidic functionality will be largely deprotinated and the ion will have a net negative charge. Oppositely, at low pH, the amine group is largely protinated and the compound will have a net positive charge. bitc wales leadership board
