Chirality (chemistry)

Two enantiomers of a generic amino acid that is chiral

(S)-Alanine (left) and (R)-alanine (right) in zwitterionic form at neutral pH

Chirality /kaɪˈrælɪti/ is a geometric property of some molecules and ions. A chiral molecule/ion is non-superposable on its mirror image. The presence of an asymmetric carbon atom is one of several structural features that induce chirality in organic and inorganic molecules. The term chirality is derived from the Greek word for hand, χειρ (kheir).
