Chirality

（重定向自Amphichiral）

Two enantiomers of a generic amino acid that is chiral

An achiral 3D object without central symmetry or a plane of symmetry

A table of all prime knots with seven crossings or fewer (not including mirror images).

Animation of left-handed (anti-clockwise), circularly polarized, light as viewed in the direction of the source, in agreement with physics and astronomy conventions.

Chirality /kaɪˈrælɪtiː/ is a property of asymmetry important in several branches of science. The word chirality is derived from the Greek, χειρ (kheir), "hand", a familiar chiral object.

An object or a system is chiral if it is distinguishable from its mirror image; that is, it cannot be superposed onto it. Conversely, a mirror image of an achiral object, such as a sphere, cannot be distinguished from the object. A chiral object and its mirror image are called enantiomorphs (Greek opposite forms) or, when referring to molecules, enantiomers. A non-chiral object is called achiral (sometimes also amphichiral) and can be superposed on its mirror image. If the object is non-chiral and is imagined as being colored blue and its mirror image is imagined as colored yellow, then by a series of rotations and translations the two can be superposed producing green with none of the original colors remaining.
