Chirality

Chirality (Greek handedness, derived from the word stem χειρ~, ch[e]ir~ – hand~) is an asymmetry property important in several branches of science. An object or a system is called chiral if it differs from its mirror image. Such objects then come in two forms, which are mirror images of each other, and these pairs of mirror image objects are called enantiomorphs (Greek opposite forms) or, when referring to molecules, enantiomers. A non-chiral object is called achiral (sometimes also amphichiral).
