Dear sanan

a zwitterionic compound or zwitterion  is a chemical compound with a positive and a negative formal charge on different atoms and a total net charge of zero. In fact, a zwitterion is not an ion, because the compound as a whole is electronically neutral. Zwitterions are sometimes also called inner salts

Amino acids as zwitterions

Zwitterions in simple amino acid solutions

An amino acid has both a basic amine group and an acidic carboxylic acid group.

There is an internal transfer of a hydrogen ion from the -COOH group to the -NH2 group to leave an ion with both a negative charge and a positive charge.

This is called a zwitterion.


This is the form that amino acids exist in even in the solid state. If you dissolve the amino acid in water, a simple solution also contains this ion.

A zwitterion is a compound with no overall electrical charge, but which contains separate parts which are positively and negatively charged.


All the best.
