Enantiomaatit

Enantiomers, also known as optical isomers, are pairs of molecules that are mirror images of each other but are not superimposable. They are characterized by the presence of one or more chiral centers, which are atoms bonded to four different groups. Enantiomers have identical physical and chemical properties, except when interacting with other chiral molecules or in the presence of polarized light. This is because they rotate plane-polarized light in equal but opposite directions. Enantiomers are crucial in various fields, including pharmacology, where one enantiomer may have therapeutic effects while the other is inactive or even toxic. The study of enantiomers is a significant area of research in chemistry and biology, with applications in drug development, materials science, and more. The term "enantiomer" comes from the Greek words "enantios," meaning "opposite," and "meros," meaning "part." The concept of enantiomers was first introduced by the French chemist Jean-Baptiste Biot in 1833. Enantiomers can be separated using various methods, such as chiral chromatography or crystallization with a chiral auxiliary. The study of enantiomers has led to the development of chiral synthesis, which involves the creation of enantiomerically pure compounds. This has opened up new avenues in the design and synthesis of complex molecules with specific properties. Enantiomers are also found in nature, with many biological molecules, such as amino acids and sugars, existing as pairs of enantiomers. The study of enantiomers has contributed to our understanding of molecular chirality and its role in biological systems.
