(S)-enantiomer

Definition

The (S)-enantiomer is one of the two possible stereoisomeric forms of a chiral molecule, where the 'S' refers to the spatial arrangement of the substituents around the chiral center. The (S)-enantiomer is a non-superimposable mirror image of the (R)-enantiomer, and the two forms often have different biological and chemical properties.
