Definition of enantiomer in English:

enantiomer

noun ɪˈnantɪə(ʊ)məɛˈnantɪə(ʊ)məəˈnæntioʊmər

Chemistry

Each of a pair of molecules that are mirror images of each other.
〔化〕对映（结构）体
Example sentencesExamples
- Racemic mixtures contain equal amounts of the two enantiomers.
- As with hands, chiral molecules can occur in two different forms, called enantiomers, which are mirror-images of one another.
- Recently, though, it was discovered that life itself can generate a particular enantiomer or chiral form of a particular molecule.
- This development has made it easier to monitor pesticide enantiomers that differ significantly in their toxicity.
- Such isomers are called enantiomers and molecules that have enantiomers are said to be chiral or to show chirality.
- One of the principal barriers to high yield is the creation of both enantiomers of a chiral compound, when only one is desired.

Derivatives

enantiomeric

adjective ɪnantɪə(ʊ)ˈmɛrɪkɛnantɪə(ʊ)ˈmɛrɪk

Chemistry

There is no symmetry to this molecule, and it exists in the two enantiomeric forms.
Example sentencesExamples
- The reactions proceed at room temperature without solvent, giving enantiomeric excesses of 99.8 per cent.
- In my view, it is dangerous to rely on enantiomeric ratios of protein amino acids because of the omnipresent problem of terrestrial contamination.
- Barron showed theoretically that a magnetic field alone cannot produce an enantiomeric excess, and at the time called magnetic optical activity ‘false chirality’.
- This enantiomerically enriched catalyst could then act to promote the formation of amino acids with substantial enantiomeric excesses.

enantiomerically

adverb

Chemistry

Their efficiency, together with that of the now highly optimised extraction processes, mean that the plant remains unchallenged as the commercial source of enantiomerically pure morphine and codeine.
Example sentencesExamples
- This enantiomerically enriched catalyst could then act to promote the formation of amino acids with substantial enantiomeric excesses.
- The flavour and fragrance industry takes advantage of chirality - by being able to produce enantiomerically pure compounds, manufacturers can not only expand their product ranges but also guarantee customers product uniformity.
- The phosphine that was used was not enantiomerically pure, but even so the resulting product showed a 15 per cent enantiomeric excess.

Origin

1930s: from Greek enantios 'opposite' + -mer.
