Voorbeelden van het gebruik van ENANTIOMER in een zin

• Like almost all other amino acids, the α-carbon is chiral and lysine may refer to either enantiomer or a racemic mixture of both.
• It is solely a relationship of chirality and the permanent three-dimensional relationships among molecules or other chemical structures: no amount of re-orientiation of a molecule as a whole or conformational change converts one chemical into its enantiomer.
• Dextroamphetamine (INN: dexamfetamine) is a potent central nervous system (CNS) stimulant and enantiomer of amphetamine that is prescribed for the treatment of attention deficit hyperactivity disorder (ADHD) and narcolepsy.
• Enantiomers of a compound with more than one stereocenter are also diastereomers of the other stereoisomers of that compound that are not their mirror image (that is, excluding the opposing enantiomer).
• The (+) enantiomer itself has the major pharmacologic effects and does not induce many of the detrimental side-effects of the mixture.
• For a chiral molecule with one or more stereocenter, the enantiomer corresponds to the stereoisomer in which every stereocenter has the opposite configuration.
• A consequence of this is that some aldaric acids are meso forms with no optical activity despite their multiple chiral centers—this occurs if a sugar and its enantiomer oxidize to the same aldaric acid.
• Tröger's base and its analogs can be resolved by various methods including chiral HPLC or be made as a single enantiomer.
• Homochirality can also refer to enantiopure substances in which all the constituents are the same enantiomer (a right-handed or left-handed version of an atom or molecule), but some sources discourage this use of the term.
• Examples of syntheses performed using the optically active enantiomer of this diketone as a starting material are that of ancistrofuran and the Danishefsky total synthesis of Taxol.
• This compound is commercially available as a single enantiomer and the single chiral group present in this molecule is able to drive the entire sequence of organic reactions to a single optically active Taxol endproduct.
• In the enolate oxidation of the cyclopentadienone below with either camphor enantiomer, the trans isomer is obtained because access for the hydroxyl group in the cis position is limited.
• The reaction is mediated by a D-fructose derived catalyst, which produces the (R,R) enantiomer of the resulting epoxide.
• Enantiomer self-disproportionation is a process in stereochemistry describing the separation of a non-racemic mixture of enantiomers in an enantioenriched fraction and a more racemic fraction as a result of the formation of heterochiral or homochiral aggregates.
• Though enantioselective syntheses have been reported, racemic grandisol has proven equally effective at attracting boll weevils as the natural enantiomer, rendering moot the need for enantioselective syntheses for agricultural purposes.
• The older name of RRR-α-tocopherol is d-α-tocopherol, but this d/l naming should no longer be used, because whether l-α-tocopherol should mean SSS enantiomer or the SRR diastereomer is not clear, from historical reasons.
• In analytical chemistry, a chiral derivatizing agent (CDA), also known as a chiral resolving reagent, is a derivatization reagent that is a chiral auxiliary used to convert a mixture of enantiomers into diastereomers in order to analyze the quantities of each enantiomer present and determine the optical purity of a sample.
• Rather, it indicates the compound's stereochemistry relative to that of the dextrorotatory or levorotatory enantiomer of glyceraldehyde.
• One method for this is the use of camphorsulfonic acid, in which the basic group of NOBIN is used to form a diastereomeric salt of one enantiomer.
• It is the S enantiomer of norfluoxetine, the main active metabolite of the widely used antidepressant fluoxetine; it is nearly 4 times more selective for stimulating neurosteroid synthesis relative to serotonin reuptake inhibition than fluoxetine.
• 1,3-Butanediol has sedative, hypotensive and hypoglycaemic action comparable to ethanol, with the (R) enantiomer being more active.
• It is the enantiomer of emtricitabine, a widely used NRTI, meaning that the two compounds are mirror images of each other.
• These diastereomers may be separated by column chromatography and hydrolyzed to obtain each enantiomer of Pirkle's alcohol in enantiopure form.
• The ethers, esters and enantiomers of the above mentioned substances, with exception of dextromethorphan (INN) as enantiomer of levomethorphan and racemethorphan, and with exception of dextrorphanol (INN) as enantiomere of levorphanol and racemorphan;.
• The final reduction reaction uses sodium borohydride, which in cold methanol gives almost exclusively the diastereomer pair having the absolute configuration (2R,3R) and its enantiomer (2S,3S), with only about 2% of the alternative (2R,3S) and (2S,3R) isomers.
