  2. Enantiomer - Wikipedia

    en.wikipedia.org/wiki/Enantiomer

    There are three common naming conventions for specifying one of the two enantiomers (the absolute configuration) of a given chiral molecule: the R/S system is based on the geometry of the molecule; the (+)- and (−)- system (also written using the obsolete equivalents d- and l-) is based on its optical rotation properties; and the D/L system is based on the molecule's relationship to ...

  3. Chirality - Wikipedia

    en.wikipedia.org/wiki/Chirality

    In chemistry, chirality usually refers to molecules. Two mirror images of a chiral molecule are called enantiomers or optical isomers. Pairs of enantiomers are often designated as "right-", "left-handed" or, if they have no bias, "achiral". As polarized light passes through a chiral molecule, the plane of polarization, when viewed along the ...

  4. Chiral inversion - Wikipedia

    en.wikipedia.org/wiki/Chiral_inversion

    Chiral inversion is the process of conversion of one enantiomer of a chiral molecule to its mirror-image version with no other change in the molecule. [1] [2] [3] [4]Chiral inversion happens depending on various factors (viz. biological-, solvent-, light-, temperature- induced, etc.) and the energy barrier energy barrier associated with the stereogenic element present in the chiral molecule. 2 ...

  5. Enantioselective synthesis - Wikipedia

    en.wikipedia.org/wiki/Enantioselective_synthesis

    Enantioselective synthesis, also called asymmetric synthesis, [1] is a form of chemical synthesis.It is defined by IUPAC as "a chemical reaction (or reaction sequence) in which one or more new elements of chirality are formed in a substrate molecule and which produces the stereoisomeric (enantiomeric or diastereomeric) products in unequal amounts."

  6. Kinetic resolution - Wikipedia

    en.wikipedia.org/wiki/Kinetic_resolution

    In organic chemistry, kinetic resolution is a means of differentiating two enantiomers in a racemic mixture.In kinetic resolution, two enantiomers react with different reaction rates in a chemical reaction with a chiral catalyst or reagent, resulting in an enantioenriched sample of the less reactive enantiomer. [1]

    Hundreds of Californian prisoners have been deployed to help battle the fires raging across the Los Angeles area, with some working 24-hour shifts for as little as $26.90, or just over $1 an hour.

  8. Enantiopure drug - Wikipedia

    en.wikipedia.org/wiki/Enantiopure_drug

    For example, amino acids that make up the proteins in the body have the same configuration, L-absolute configuration. Because of this specificity, vital processes such as constructing proteins, rely on stereoselectivity to ensure that out of all the potential enantiomers available, the body is utilizing the correct enantiopure compound.
