group

A zwitterion is a compound with no overall electrical charge, but which contains separate parts which are positively and negatively charged. In aqueous solution, the carboxyl group can lose a proton (becomes basic group) and amino group can accept a proton (becomes acidic) giving rise to the dipolar ion known as Zwitterions.
