In chemistry, a zwitterion ( TSVIT-ər-EYE-on; from German Zwitter [ˈtsvɪtɐ] 'hermaphrodite'), also called an inner salt or dipolar ion is a molecule that contains an equal number of positively and negatively charged functional groups. (1,2-dipolar compounds, such as ylides, are sometimes excluded from the definition.) Some zwitterions, such as amino acid zwitterions, are in chemical equilibrium with an uncharged "parent" molecule.
