手性 Chirality (chemistry)

(重定向自Chiral)
两种映射异构体的通用性氨基酸结构
(S)-丙氨酸(左)及(R)-丙氨酸(右)的两性离子形式之中性pH值
两个氟氯溴甲烷(CHBrClF)映射体

手性chirality)一词源于希腊语词干“手”χειρ(ch[e]ir),在多种学科中表示一种重要的对称特点。如果某物体与其镜像不同,则其被称为“手性的”,且其镜像是不能与原物体重合的,就如同左手和右手互为镜像而无法叠合。手性物体与其镜像被称为对映体(enantiomorph,希腊语意为“相对/相反形式”);在有关分子概念的引用中也被称为对映异构体。可与其镜像叠合的物体被称为非手性的(achiral),有时也称为双向的(amphichiral)。

Chirality

(重定向自Chiral)
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 /kˈrælɪt/ 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.
