WebApr 13, 2024 · Nature is not always ambidextrous: it sometimes favors one hand, e.g., in the chirality of amino acids. In a recent issue of Cell Reports Physical Science, Wang and Sugiyama demonstrate the transformation of a crystal from achiral to chiral, where the hand of the crystal can be selected by the hand of circularly polarized light. In chemistry, a molecule or ion is called chiral if it cannot be superposed on its mirror image by any combination of rotations, translations, and some conformational changes. This geometric property is called chirality (/kaɪˈrælɪti/). The terms are derived from Ancient Greek χείρ (cheir) 'hand'; which is the canonical example of an object with this property.
WebWhy life is chiral has puzzled scientists for well over a century. Louis Pasteur famously discovered molecular chirality in his meticulous experiments in 1848. He separated by hand the mirror-image forms of salts of tartaric acid and saw that their solutions will rotate the plane of polarised light in opposite directions.
WebNote, however, that D-amino acids do occur in biology, e.g., in cell walls of bacteria. Nucleic acids also have chiral centers. For example, in DNA the atoms C1', C3', and C4' are chiral, while RNA has an additional chiral center at C2'. Chirality is central to all molecular interactions in biological systems. signit softwareWebApr 14, 2024 · Chiral enantiomer recognition has important research significance in the field of analytical chemistry research.
