  2. Meso compound - Wikipedia

    en.wikipedia.org/wiki/Meso_compound

    A meso compound or meso isomer is an optically inactive isomer in a set of stereoisomers, at least two of which are optically active. [1] [2] This means that despite containing two or more stereocenters, the molecule is not chiral. A meso compound is superposable on its mirror image (not to be confused with superimposable, as any two objects ...

  3. Inositol - Wikipedia

    en.wikipedia.org/wiki/Inositol

    Inositol hexaphosphate, also called phytic acid or IP6, is a phytochemical and the principal storage form of phosphorus in many plant tissues, especially bran and seed. [13] Phosphorus and inositol in phytate form are not generally bioavailable to non- ruminant animals because these animals lack the digestive enzyme phytase required to remove ...

  4. Stereoisomerism - Wikipedia

    en.wikipedia.org/wiki/Stereoisomerism

    These include meso compounds, cis–trans isomers, E-Z isomers, and non-enantiomeric optical isomers. Diastereomers seldom have the same physical properties. In the example shown below, the meso form of tartaric acid forms a diastereomeric pair with both levo- and dextro-tartaric acids, which form an enantiomeric pair.

  5. meso-Stilbene dibromide - Wikipedia

    en.wikipedia.org/wiki/Meso-stilbene_dibromide

    meso-Stilbene dibromide is an organic compound with a formula of (C 6 H 5 CH(Br)) 2. [3] It is one of three isomeric stilbene dibromides, the others being the pair of enantiomers . All are white solids.

  6. 2,3-Butanediol - Wikipedia

    en.wikipedia.org/wiki/2,3-Butanediol

    The isomer distribution depends on the stereochemistry of the epoxide. The meso isomer is used to combine with naphthalene-1,5-diisocyanate. The resulting polyurethane is called "Vulkollan".

  7. 2,3-Epoxybutane - Wikipedia

    en.wikipedia.org/wiki/2,3-Epoxybutane

    The compound exists as three stereoisomers, a pair of enantiomers and the meso isomer. All are colorless liquids. Preparation and reactions 2,3 ...

  8. Succimer - Wikipedia

    en.wikipedia.org/wiki/Succimer

    It occurs in two diastereomers, meso and the chiral dl forms. The 2,3-dimercaptosuccinic acid molecule has two stereocentres (two asymmetric carbon atoms), and can exist as three different stereoisomers. The 2S,3S and 2R,3R isomers are a pair of enantiomers, whereas the 2R,3S isomer (succimer) is a meso compound and thus optically inactive.

  9. Cahn–Ingold–Prelog priority rules - Wikipedia

    en.wikipedia.org/wiki/Cahn–Ingold–Prelog...

    A meso compound is superposable on its mirror image, therefore it reduces the number of stereoisomers predicted by the 2 n rule. This occurs because the molecule obtains a plane of symmetry that causes the molecule to rotate around the central carbon–carbon bond. [12] One example is meso-tartaric acid, in which (R,S) is the same as the (S,R) form
