Also found in: Dictionary, Thesaurus, Medical, Wikipedia.

enantiomer,

another term for optical isomer. See Stereoisomers under isomerisomer
, in chemistry, one of two or more compounds having the same molecular formula but different structures (arrangements of atoms in the molecule). Isomerism is the occurrence of such compounds. Isomerism was first recognized by J. J. Berzelius in 1827.

An S-Chiral A column (4.6 mm x 250 mm, 5 [micro]m) obtained from Acchrom (Beijing, China) was employed for the enantiomer separation.
For both human plasma and rat serum, the enantiomer ratio was close to 1, with values ranging from 0.92 to 0.99 at both concentrations of rac-MDMA tested.
Olean--one enantiomer is active against males whereas the opposite enantiomer affects females.
SCF technology is an innovative method for the stereocomplexation of PDLA and PLLA enantiomers. This study identified various SCF parameters that can affect the particle size and morphological behavior of sc-PLA, and analyzed the influence of subsequent processing such as homogenization, mechanical stirring, and sonication on these sc-PLA particles.
According to the authors, enantiomer evaluations evidence a high cis isomers bioaccumulation.
Bupivacaine is found in two different enantiomers: levobupivacaine--S (-) and dextrobupivacaine--R (+).
For each enantiomer peak in the cathinone mixture chromatogram, calibration curve was constructed using the following concentration levels: 1, 5,10, 20, 40, 60, 80, and 100 [micro]g/L.
Some enantiomer cases, too, have privileged unexpected results over obviousness to try.
In order to estimate a reliable purity by this method, the optical rotation of a pure enantiomer must first be known, and a sufficient amount of a pure sample, for instance 20 mg or even more, must be prepared for the polarimetric measurement.
When polymer is exposed to a racemate solution the polymer adsorbs one of the enantiomer with notable selectivity [7 8].
This makes it possible for the olfactory receptors to distinguish between enantiomers. Many enantiomers of fragrance molecules are perceived differently by our sense of smell.
