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.

Enantiopure Hydroxylactones from L-ascorbic and D-isoascorbic acids.
The next five chapters discuss separations, offering treatments of resolution of chiral drugs and drug intermediates by crystallization, isolation and production of optically pure drugs by enantioselective (able to select one of a chiral pair) chromatography, stereoselective chromatographic methods for drug analysis, capillary electrophoresis coupled to mass spectrometry for chiral drugs analysis, and chiral molecular tools for preparation of enantiopure alcohols and simultaneous determination of their absolute configurations by x-ray crystallography or anisotrophy methods.
In the prebiotic atmosphere, inorganic pyrophosphates formed by photo-phosphorylating reactions and enrichment of enantiopure molecular conformations provides a thermodynamical driving force for the evolution of biogenetic process.
Carbohydrates contain several functional groups and stereogenic centres in one molecular unit, which allows the use of carbohydrates as tools in stereochemical differentiations, as starting materials in exchiral pool syntheses of interesting enantiopure compounds [4], as chiral templates in asymmetric transformations [5], and as chiral auxiliaries in stereoselective synthesis [6, 7].
