enantiomeerisellä

Enantiomeerinen refers to a relationship between molecules that are non-superimposable mirror images of each other, much like a left and right hand. These molecules are called enantiomers. The term itself originates from the Greek words "enantio" meaning opposite and "meros" meaning part. When a molecule possesses a chiral center, typically a carbon atom bonded to four different groups, it can exist as two enantiomeric forms. These enantiomers have identical physical properties such as melting point, boiling point, and solubility, with the exception of their interaction with plane-polarized light. One enantiomer will rotate the plane of polarized light in a clockwise direction (dextrorotatory), while its mirror image will rotate it in the counter-clockwise direction (levorotatory). The interaction of enantiomers with other chiral molecules, however, can be significantly different. This stereospecificity is of immense importance in biological systems, where enzymes and receptors are chiral. Consequently, one enantiomer of a drug may be therapeutically active, while the other is inactive or even toxic. The synthesis of specific enantiomers, known as asymmetric synthesis, is a crucial area of organic chemistry.
