Either of a pair of crystals, molecules, or compounds that are mirror images of each other but are not identical, and that rotate the plane of polarized light equally, but in opposite directions. Also called enantiomer, optical isomer.

[Greek enantios, opposite + -MORPH.]

n.pl

Two isomers whose structures, dextro- and levo-, differ only in a spatial arrangement that makes them mirror images. This occurs only when there is an asymmetric carbon atom—that is, one attached to four different substituents. The pharmacologic activity often resides very largely in one of the two forms.

One of a pair of isomeric substances, the molecular structures of which are mirror opposites of each other.

[fr. Gk enantios, opposite + -morph, form]   /eh NAN tee uh morf/
a form which is related to another as an object is related to its image in a mirror; a mirror image
