chirality centre

Synonym: centre of chirality
An atom holding a set of @L03518@ in a spatial arrangement which is not superposable on its mirror image. A @C01058@ centre is thus a generalized extension of the concept of the @A00479@ to central atoms of any element, for example N+abcd, Pabc as well as Cabcd.
