enantiomers


Also found in: Dictionary, Thesaurus, Encyclopedia.

enantiomers (i·nanˑ·tē··merz),

n.pl molecules that are nonsuperimposable mirror images of one another resulting from the chirality exhibited by organic compounds (containing an asymmetrical carbon); enantiomers differ in their ability to rotate plane-polarized light. Also called
enantiomorphs. See also chirality.

83) The chemical literature indicated at least ten separation techniques that could be tried, and Sanofi's actual approach--diasteromeric salt formation--required five months of experimenting with "diverse salt-forming compositions and conditions, in the hope of coming upon a lucky combination of reagents that will preferentially select one of the enantiomers and crystallize from the solution in optically pure form.
1986) Resolution of enantiomers by HPLC on optically active poly(triphenylmethyl methacrylate).
The L-Phe and D-Phe imprinted membranes prepared by AA and AN successfully recognize template facilitate permeation of template and reject other enantiomer.
It is also interesting to note that there were detectable antipode present in both single enantiomer standards (S(+) carvone and R(-) carvone).
A combination of methanol/acetonitrile/water in the mobile phase is mandatory for separation of HBCD enantiomers [99].
The S(+) enantiomer is associated with prostaglandin inhibition and toxicity and the R(-) enantiomer is linked with analgesic action and protection of gastrointestinal tract.
Of all the forms, the studies of its threo diastereomer revealed that d-threo isomer has been found to be more active and also showed significant metabolic difference than l-threo enantiomer.
114) An equal mixture of enantiomers is termed a racemic mixture.
The common analogy used to illustrate the relationship between enantiomers is the relationship between a left and a right hand.
The system is suited for chiral separations where large volumes of enantiomers are being purified by stacked injections.
As to novelty, it was common ground, consistent with EPO and English case law (in contrast, for example, to that in Germany as to this issue), that the prior disclosure of a racemate did not in itself amount to a disclosure of each of its enantiomers.
