Stereospecificity

Definition
noun
Relate to the specific points along the chain of configurations resulting in the spatial arrangement of atom in a polymer to create simple stereoisomer.
Supplement
Produces in a stereochemically specific processes thus, having crystalline properties like synthetic natural rubber (cis-polyisoprene).
Demonstrate distinct specificity of one of several stereoisomers of reactants of the said enzymes for organic reactions.
The value of stereospecificity is focus on the reactants and stereochemistry which is concerned with the products as long as it presents confirmation of a disparity in measures between stereoisomeric reactants that act on its own specific way.
A stereospecific method denotes the stereochemical result of a specified reactant, while a stereoselective method chooses products that are available on a given reactant. In a single component, a stereospecific means will provide 100% of a particular stereoisomer though loss of stereochemical reliability can basically happen through opposing means with different stereochemical result.
For example in nucleophilic substitution at sp3 at the center which can carry on by the stereospecific system that will result through inversion or non-specific mechanism which explain a simple selectivity for inversion depending on the reactants and the condition of the reactants that affected by some factors like temperature, solvent and substrate. If the substitution resulted in incomplete inversion it is because in the mechanisms at the center or double inversion.
