WHAT DOES ENANTIOMER MEAN IN ENGLISH?

Enantiomer

In chemistry, an enantiomer is one of two stereoisomers that are mirror images of each other that are non-superposable, much as one's left and right hands are the same except for opposite orientation. Organic compounds that contain a chiral carbon usually have two non-superposable structures. These two structures are mirror images of each other and are, thus, commonly called enantiomorphs, hence this structural property is now commonly referred to as enantiomerism. Enantiopure compounds refer to samples having, within the limits of detection, molecules of only one chirality. Enantiomers have, when present in a symmetric environment, identical chemical and physical properties except for their ability to rotate plane-polarized light by equal amounts but in opposite directions. A mixture of equal parts of an optically active isomer and its enantiomer is termed racemic and has zero net rotation of plane-polarized light because the positive rotation of each form is exactly counteracted by the negative rotation of a one. Enantiomers of each other often show different chemical reactions with other substances that are also enantiomers.

Definition of enantiomer in the English dictionary

The definition of enantiomer in the dictionary is a molecule that exhibits stereoisomerism because of the presence of one or more chiral centres.
