Enantiomers are a type of isomers that are mirror images of each other but not superimposable. They have the same molecular formula and physical properties but different biological activities. Enantiomers are important in pharmaceuticals, as one enantiomer may have therapeutic effects while the other enantiomer could be toxic. The term “enantiomer” comes from the Greek words “énon” (meaning “opposite”) and “méros” (meaning “part”).
