单词	chiral
释义	chiral /ˈkʌɪr(ə)l / adjective Chemistry Asymmetric in such a way that the structure and its mirror image are not superimposable.Most alkaloids are also chiral molecules, meaning they have nonsuperimposable mirror images.... The resulting chiral nematic giant liquid crystals had wide temperature ranges for their liquid crystal phases, from room temperature to about 80° Celsius. The most common examples of chiral molecules are enantiomers. Derivatives chirality /kʌɪˈralɪti/ noun ... Such isomers are called enantiomers and molecules that have enantiomers are said to be chiral or to show chirality. All of this is achieved without switching the chirality of the catalyst. The technique might also be used to template the growth of complex molecular structures with novel architecture and chirality. Origin Late 19th century: from Greek kheir 'hand' + -al.
