In chemistry, stereospecificity is the property of a reaction mechanism that leads to different stereoisomeric reaction products from different stereoisomeric reactants, or which operates on only one (or a subset) of the stereoisomers. In contrast, stereoselectivity is the property of a reactant mixture where a non … See more Nucleophilic substitution at sp centres can proceed by the stereospecific SN2 mechanism, causing only inversion, or by the non-specific SN1 mechanism, the outcome of which can show a modest selectivity for … See more • Dynamic stereochemistry See more WebJul 1, 2024 · 4.3: Naming stereoisomers. Chemists need a convenient way to distinguish one stereoisomer from another.

While challenging to understand and visualize, the stereochemistry concepts we have explored in this chapter are integral to the study of living things. The vast majority of biological molecules contain chiral centers and/or stereogenic alkene groups. WebEnzymes have usually evolved to catalyze one reaction, or a particular class of reaction, and the level of specificity will depend on the function of the particular enzyme. In some cases, enzymes will act on a broad range of substrates, just as nature intended. Examples of the latter type of enzymes are the cytochromes P-450 and the glutathione ...
