Definition of stereoisomer in English:

stereoisomer

nounˌstɪərɪəʊˈʌɪsəməˌstɛrɪəʊˈʌɪsəməˌstɛrioʊˈaɪsəmər

Chemistry

Each of two or more compounds differing only in the spatial arrangement of their atoms.
〔化〕立体异构体
Example sentencesExamples
- One of the errors in the literature talking about ‘mateine’ is the claim that it is a stereoisomer of caffeine.
- Most importantly, stereoisomers are not spatially superimposable.
- The glycerol used to make archaeal phospholipids is a stereoisomer of the glycerol used to build bacterial and eukaryotic membranes.
- Enantiomers are stereoisomers whose molecules are nonsuperposable mirror-images of each other.
- For instance, in the case of the two active stereoisomers we showed that only the stereochemistry at the amine and hydroxyl functions on the scaffold were important - the third chiral centre is not.

Derivatives

stereoisomeric

adjectiveˌstɛrɪəʊʌɪsəˈmɛrɪk

Chemistry

As tartaric acid possesses two stereogenic carbon atoms, it exists in three stereoisomeric forms.
Example sentencesExamples
- However, significant differences in the structure of the two linked channels, which arise from a different orientation of the two stereoisomeric forms of the dioxolane ring with respect to the axis of the pore, were identified.
- The structural and thermodynamic features of these stereoisomeric adducts are also discussed in relation to their reported low susceptibilities to nucleotide excision repair.

stereoisomerism

noun

Chemistry

In this Topic, we will concentrate on stereoisomerism in organic compounds, although this phenomenon also occurs in other compounds such as transition metal complexes.
Example sentencesExamples
- Thereby, stereochemistry and stereoisomerism have been discussed on a common basis.
- A second type of stereoisomerism are not mirror images of one another.
- The second major type of isomerism is stereoisomerism.
- Structural isomerism is not a form of stereoisomerism, and is dealt with on a separate page.
