One of the two meso isomers of 1,2,3,4-tetrafluorospiropentane, with S 4 symmetry. Since a meso isomer has a superposable mirror image, a compound with a total of n chiral centers cannot attain the theoretical maximum of 2 n stereoisomers if one of the stereoisomers is meso. [4] A meso isomer need not have a mirror plane.
Two kinds of stereoisomers. In stereochemistry, stereoisomerism, or spatial isomerism, is a form of isomerism in which molecules have the same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space.
There are nine stereoisomers, that differ by the position of the hydroxyl groups relative to the mean plane of the ring. All these compounds are sometimes called inositol , although this name (especially in biochemistry and related sciences) most often refers to a particular isomer, myo -inositol , which has many important physiological roles ...
meso or cis: Interactive image; S,S: Interactive image; R,R: ... The compound exists as three stereoisomers, a pair of enantiomers and the meso isomer. All are ...
myo-Inositol is a meso compound, meaning it is optically inactive because it has a plane of symmetry. [10] It is a white crystalline powder, relatively stable in the air. It is highly soluble in water, slightly soluble in glacial acetic acid , ethanol , glycol , and glycerin , but insoluble in chloroform and ether .
Isomers themselves exist in many varieties but can generally be classified as structural isomers or stereoisomers. Structural isomers have a different ordering of bonds and/or different bond connectivity from one another, as in the case of hexane and its four other isomeric forms ( 2-methylpentane , 3-methylpentane , 2,2-dimethylbutane , and 2 ...
See: E-Z notation Violet leaf aldehyde, systematic name (E,Z)-nona-2,6-dienal, is a compound having one (E)- and one (Z)-configured double bond. The descriptors (E) (from German entgegen, 'opposite') and (Z) (from German zusammen, 'together') are used to provide a distinct description of the substitution pattern for alkenes, cumulenes or other double bond systems such as oximes.
The meso-form is the second most abundant in nature, after 3R,3′R-zeaxanthin, which is produced by plants and algae. [1] Meso-zeaxanthin has been identified in specific tissues of marine organisms [2] and in the macula lutea, also known as the "yellow spot" of the human retina. [3] [4]
