- n. See enantiomorph.
Wiktionary
- n. One of a pair of stereoisomers that is the mirror image of the other, but may not be superimposed on this other stereoisomer. Almost always, a pair of enantiomers contain at least one chiral center, and a sample of either enantiomer will be optically active.
GNU Webster's 1913
- n. either of a pair of optical isomers of a chemical substance whose molecules are mirror images of each other, i. e., are related to each other as a right-handed to a left-handed glove; -- meaningful only for structures which have internal asymmetry.
WordNet 3.0
- n. either one of a pair of compounds (crystals or molecules) that are mirror images on each other but are not identical
Etymologies
- Greek enantios, opposite; see ant- in Indo-European roots + -mer(e).
Examples
“When switching dosage forms, if the prescriber does not obtain the desired therapeutic endpoint in spite of education about the extensive differences in inhalers, there are alternatives - use of a spacer, increased dose causing more side effects or switching to Xopenex, the R- enantiomer which is the active portion of the racemic albuterol.”

“Nexium is only the S-enantiomer; Prilosec is a racemic mixture.”
“In the context of any electrical field capable of orienting highly polar sugar derivatives, you'd have both selection of ribose, as it binds more closely to the surface, and of one particular enantiomer of ribose.”
“This is a serious problem because experiments on template-directed synthesis using poly© and the imidazolides of G suggest that the polymerization of the D-enantiomer is often strongly inhibited by the”

“Nonenzymatic replication may be more resistant to poisoning by the incorrect enantiomer than previously seemed likely.”

“Strongly autocatalytic processes can be successfully catalysed by relatively small populations of catalyst in this case reaction product, and while we tend to assume that our flask of racemic material is purely 50:50 of each enantiomer, reality is more complex.”

“The second discovery on which Knowles 'pioneering work is based on, is Horner's and Mislow's syntheses of chiral phosphines, for example the enantiomer B shown in figure 3.”
