WebAn 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 -NH 2 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.
