As we learnt that

Zwitter ion -

A molecule with dipolar ends ( an acidic end and a basic end )

- wherein

In aqueous solution,

-NH_{2} and -COOH group undergo ionization

-NH_{2} accepts H^{+} and becomes NH_{3}^{+} and -COOH losses H^{+} and becomes -COO^{-}

 

 

NH_{2}-CH_{2}-COOH \rightleftharpoons H_{3}\overset{+}N-CH_{2}-COO^{-}

                                                                Zwitter ion
