WitrynaChirality is another form of isomerism. Chiral isomers are non-superimposable mirror images of each other, i.e. they are the same molecules with one of them being what …
Chirality is important in context of ordered phases as well, for example the addition of a small amount of an optically active molecule to a nematic phase (a phase that has long range orientational order of molecules) transforms that phase to a chiral nematic phase (or cholesteric phase). Zobacz więcej 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 … Zobacz więcej The chirality of a molecule is based on the molecular symmetry of its conformations. A conformation of a molecule is chiral if and only if it belongs to the Cn, Dn, T, O, I point groups (the chiral point groups). However, whether the molecule itself is considered to be chiral … Zobacz więcej • Flavor: the artificial sweetener aspartame has two enantiomers. L-aspartame tastes sweet whereas D-aspartame is tasteless. • Odor: R-(–)-carvone smells like spearmint whereas S-(+) … Zobacz więcej Chirality is a symmetry property, not a property of any part of the periodic table. Thus many inorganic materials, molecules, and ions are … Zobacz więcej A stereogenic center (or stereocenter) is an atom such that swapping the positions of two ligands (connected groups) on that atom results in a molecule that is stereoisomeric to the original. For example, a common case is a tetrahedral carbon bonded … Zobacz więcej Many biologically active molecules are chiral, including the naturally occurring amino acids (the building blocks of proteins) and sugars. The origin of this Zobacz więcej The term optical activity is derived from the interaction of chiral materials with polarized light. In a solution, the (−)-form, or levorotatory form, of an optical isomer rotates the … Zobacz więcej Witryna8 wrz 2016 · For this purpose, p-tert-butylcalix[6]arene derivative has been used as chiral selector for the chiral enantiorecognition of warfarin in a UV-spectral study coupled with the multivariate analysis of the spectral data.
