stereoisomerism

ster·e·o·i·som·er·ism

S0743500 (stĕr′ē-ō-ī-sŏm′ə-rĭz′əm, stîr′-)n. Isomerism created by differences in the spatial arrangement of atoms in a molecule.

ster′e·o·i′so·mer′ic (-ī′sə-mĕr′ĭk) adj.

stereoisomerism

(ˌstɛrɪəʊaɪˈsɒməˌrɪzəm; ˌstɪər-) n (Chemistry) chem isomerism caused by differences in the spatial arrangement of atoms in molecules stereoisometric adj

ster•e•o•i•som•er•ism

(ˌstɛr i oʊ aɪˈsɒm əˌrɪz əm, ˌstɪər-)

n. the isomerism ascribed to different relative positions of the atoms or groups of atoms in the molecules of organic compounds. [1890–95]

stereoisomerism

Isomers of a compound which have the same formula and functional groups and differ only in the arrangements of groups in space are stereoisomers.

stereoisomerism

[ster″e-o-i-som´er-izm] the relationship between two or more isomers that have the same structure (the same linkages between atoms) but different configurations (spatial arrangements), in contrast to constitutional isomerism in which the isomers have different structures. Stereoisomers are further classified into enantiomers, those having molecules that are mirror images of each other, and diastereoisomers, those that do not. adj., adj stereoisomer´ic.

Stereoisomerism, exemplified by a pair of cis-trans diastereoisomers. From Dorland's, 2000.

ster·e·o·i·som·er·ism

(ster'ē-ō-ī-som'ĕr-izm), Molecular asymmetry, isomerism involving different spatial arrangements of the same groups (for example, androsterone and isoandrosterone, differing only in that one has a 3α-OH, the other a 3β-OH).
See also: stereoisomer, Le Bel-van't Hoff rule. Synonym(s): stereochemical isomerism

ster·e·o·i·som·er·ism

(ster'ē-ō-ī-som'ĕr-izm) Molecular asymmetry; isomerism involving different spatial arrangements of the same groups.

stereoisomerism

Mirror-image molecular asymmetry. Also known as CHIRALITY. In the case of amino acids, the two forms are represented on paper with the carboxyl group of the carbon chain at the top. In the Laevo (L) form, the functional groups connected to the central carbon or carbon chain are shown as projecting to the left and in the dextro (D) form they are shown projecting to the right.

Stereoisomerism Stereoisomerism a type of isomerism characterized by different spatial arrangements of atoms in a molecule with no change in the arrangement of the bonds.
