A chiral molecule is a type of molecule that has a non-superposable mirror image. The feature that is most often the cause of chirality in molecules is the presence of an asymmetric carbon atom. [16] [17] The term "chiral" in general is used to describe the object that is non-superposable on its mirror image. [18]
A chiral molecule or ion exists in two stereoisomers that are mirror images of each other, [5] called enantiomers; they are often distinguished as either "right-handed" or "left-handed" by their absolute configuration or some other criterion. The two enantiomers have the same chemical properties, except when reacting with other chiral compounds.
Direct application of mirror-chiral organisms can be mass production of enantiomers (mirror-image) of molecules produced by normal life. Enantiopure drugs - some pharmaceuticals have shown different activity depending on enantiomeric form, Aptamers (L-ribonucleic acid aptamers): "That
No mirror-image life exists, ... Chirality is the simple fact that molecules — like sugars and amino acids — point in one of two directions. ... life uses only one chiral form of each molecule ...
The report said that if a cell with natural chirality can be created from lifeless molecules, then, in theory, a mirror-image cell could be created from mirror-image molecules using the same methods.
Chemical compounds that come as mirror-image pairs are referred to by chemists as chiral or handed molecules. [1] Each twin is called an enantiomer. Drugs that exhibit handedness are referred to as chiral drugs. Chiral drugs that are equimolar (1:1) mixture of enantiomers are called racemic drugs
The term chiral / ˈ k aɪ r əl / describes an object, especially a molecule, which has or produces a non-superposable mirror image of itself. In chemistry , such a molecule is called an enantiomer or is said to exhibit chirality or enantiomerism .
Enantiomer molecules are like right and left hands: one cannot be superposed onto the other without first being converted to its mirror image. [5] It is solely a relationship of chirality and the permanent three-dimensional relationships among molecules or other chemical structures: no amount of re-orientiation of a molecule as a whole or ...
