Chirality

Chirality is a property of asymmetry important in several branches of science. The word "chirality" comes from the Greek χειρ, "hand", a familiar chiral object. Object or system is chiral if it differs from its mirror image, that is, it can not be imposed on him. Conversely, the mirror image achiral object, such as a sphere, cannot be separated from the object. A chiral object and its mirror image are called enantiomorphs Greek "opposite forms" or, when referring to molecules, enantiomers. Not a chiral object is called achiral sometimes amphichiral and can be superimposed on its mirror ima ...

Axial chirality

Axial chirality is a special case of chirality in which a molecule does not possess a stereogenic center but an axis of chirality, an axis about which a set of substituents is held in a spatial arrangement that is not superposable on its mirror image. Axial chirality is most commonly observed in atropisomeric substituted biaryl compounds wherein the rotation about the aryl–aryl bond is restricted, for example, various biphenyls, binaphthyls such as BINAP, and certain dihydroanthracenone compounds. Certain allene compounds and spirans also display axial chirality. The enantiomers of axially ...

                                               

Supramolecular chirality

In chemistry, the term supramolecular chirality is used to describe supramolecular assemblies that are not superposable on their mirror images. Chirality in supramolecular chemistry involves not symmetric arrangement of molecular components in a noncovalent Assembly. Chirality can arise in a supramolecular system, if one component of a chiral or achiral if components arranged in non-symmetrical way of getting super, which is chiral.

                                               

Planar chirality

Planar chirality is a special case of chirality for two dimensions. Most importantly, planar chirality is a mathematical term which finds wide application in chemistry, physics and exact Sciences, e.g. astronomy, optics and metamaterials. Recent developments in the latter two areas are dominated microwave applications and the micro - and nanostructured planar interfaces for visible and infrared light.

                                               

Inherent chirality

In chemistry, inherent chirality is a property of asymmetry of the molecules, arising not from a stereogenic or chiral center, but from the twisting of the molecule in 3-D space. The term was first coined Volker böhmer in review 1994 to describe the chirality calixarenes related to their non-planar structures in 3-D space. This phenomenon has been described as the result of "the lack of space symmetry or an inversion center in the molecule as a whole." Boehmer explains this phenomenon, suggesting that if the original chiral macrocycle calixarenes were opened it would produce an "achiral li ...

                                               

Chirappuram

Chirappuram is a hamlet within the larger village Ayroor, in Pathanamthitta district in southern Kerala, India. It is about 4km east of the village capital, Cherukolpuzha. Chirappuram is basically a junction on the two roads: Thekkumlal -Mookkannur and Edappavoor -Vettikkadu. The junction has a few shops and a Sree Narayan Guru Mandiram. The 100 year old Edappavoor MTLP school and St Thomas Marthoma Church are just few hundred metres away from this junction.

Chirality in everyday life.

Life It is All Left Handed, and We Dont Know Why: Futurism. 31 Mar 2010 Chiral molecules in living organisms in Nature exist almost exclusively as single enantiomers, a property that is critical for molecular recognition. Enantiomers. Chiral Nanomaterials and Chiral Light Optics & Photonics News. 20 Sep 2015 One reason that chiral molecules may be selected for is that shape is one of the most powerful distinguishing factor in binding selectivity.
