enantiomer /ɪˈnantɪə(ʊ)mə / /ɛˈnantɪə(ʊ)mə/noun ChemistryEach of a pair of molecules that are mirror images of each other.Such isomers are called enantiomers and molecules that have enantiomers are said to be chiral or to show chirality....- As with hands, chiral molecules can occur in two different forms, called enantiomers, which are mirror-images of one another.
- One of the principal barriers to high yield is the creation of both enantiomers of a chiral compound, when only one is desired.
Derivativesenantiomeric /ɪnantɪə(ʊ)ˈmɛrɪk/ /ɛnantɪə(ʊ)ˈmɛrɪk/ adjective ...- The reactions proceed at room temperature without solvent, giving enantiomeric excesses of 99.8 per cent.
- There is no symmetry to this molecule, and it exists in the two enantiomeric forms.
- This enantiomerically enriched catalyst could then act to promote the formation of amino acids with substantial enantiomeric excesses.
enantiomerically adverb ...- 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.
- 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.
