  2. Chirality - Wikipedia

    en.wikipedia.org/wiki/Chirality

    Also, for artificial compounds, including medicines, in case of chiral drugs, the two enantiomers sometimes show remarkable difference in effect of their biological actions. [29] Darvon ( dextropropoxyphene ) is a painkiller, whereas its enantiomer, Novrad ( levopropoxyphene ) is an anti-cough agent.

  3. Absolute configuration - Wikipedia

    en.wikipedia.org/wiki/Absolute_configuration

    [4] [5] The configuration of other chiral compounds was then related to that of (+)-glyceraldehyde by sequences of chemical reactions. For example, oxidation of (+)-glyceraldehyde (1) with mercury oxide gives (−)-glyceric acid (2), a reaction that does not alter the stereocenter. Thus the absolute configuration of (−)-glyceric acid must be ...

    en.wikipedia.org/wiki/3-methyl-3-octanol

    3-Methyl-3-octanol (systematically named 3-methyloctan-3-ol) is an organic compound with the chemical formula CH 3 (CH 2) 4 C(CH 3)(CH 2 CH 3)OH (also written as C 9 H 20 O).This simple tertiary alcohol is a clear colourless liquid under standard conditions, and is tasteless.

  5. Planar chirality - Wikipedia

    en.wikipedia.org/wiki/Planar_chirality

    A planar chiral derivative of ferrocene, used for kinetic resolution of some racemic secondary alcohols [1]. This term is used in chemistry contexts, [2] e.g., for a chiral molecule lacking an asymmetric carbon atom, but possessing two non-coplanar rings that are each dissymmetric and which cannot easily rotate about the chemical bond connecting them: 2,2'-dimethylbiphenyl is perhaps the ...

  6. Chirality (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Chirality_(chemistry)

    A chiral molecule or ion exists in two stereoisomers that are mirror images of each other, [5] called enantiomers; they are often distinguished as either "right-handed" or "left-handed" by their absolute configuration or some other criterion. The two enantiomers have the same chemical properties, except when reacting with other chiral compounds.

  7. Chiral phosphoric acid - Wikipedia

    en.wikipedia.org/wiki/Chiral_phosphoric_acid

    Common examples of Ar include Ar = 4-NO 2-C 6 H 4, 9-anthracenyl, and 2, 4, 6-iPr 3-C 6 H 2 (commonly known as TRIP [1]). In organic chemistry, chiral phosphoric acids are esters of phosphoric acid H 3 PO 4 that have chiral backbones. Well known examples include cyclic diesters derived from the BINOL and TADDOL motifs.

  8. β-Hydroxybutyric acid - Wikipedia

    en.wikipedia.org/wiki/Β-Hydroxybutyric_acid

    β-Hydroxybutyric acid, also known as 3-hydroxybutyric acid or BHB, is an organic compound and a beta hydroxy acid with the chemical formula CH 3 CH(OH)CH 2 CO 2 H; its conjugate base is β-hydroxybutyrate, also known as 3-hydroxybutyrate. β-Hydroxybutyric acid is a chiral compound with two enantiomers: D-β-hydroxybutyric acid and L-β-hydroxybutyric acid.

  9. Chirality timeline - Wikipedia

    en.wikipedia.org/wiki/Chirality_timeline

    Chiral molecules in the receptors in our noses can tell the difference between these things. Chirality affects biochemical reactions, and the way a drug works depends on what kind of enantiomer it is. Many drugs are chiral and it is important that the shape of the drug matches the shape of the cell receptor it is meant to affect.
