WebIn mathematics, chirality is the property of a figure that is not identical to its mirror image. Mathematics [ edit] 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). Main article: Chirality (mathematics) WebIf a molecule contains two or more chiral centers and does not have a plane of symmetry, it is chiral. If is has a plane of symmetry, it is an achiral meso compound. Pairs of enantiomers have the same physical properties but behave differently in a chiral environment such as a chiral binding site in an enzyme.

WebApr 28, 2024 · An object that is chiral is an object that can not be superimposed on its mirror image. Chiral objects don't have a plane of symmetry. An achiral object has a plane of symmetry or a rotation-reflection axis, i.e. reflection gives a rotated version. Optical isomers or enantiomers are stereoisomers which exhibit chirality. Optical isomerism is of ...
