Specificity of Enzyme: An Overview of Enzyme Specificity along with FAQs

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 WebAbout this unit.
