These are non-superimposable mirror images of each other. They do not have a plane of symmetry. They can rotate plane-polarized light and are optically active. Chirality is a property of molecules. It refers to the whole molecule and not an atom.

WebMay 4, 2009 · To complicate matters, chiral selection can be short-circuited and efficacy and toxicity data misinterpreted if a drug undergoes chiral inversion—the conversion of one enantiomer into its opposite (e.g., Fig. 7B) (Ali et al., 2007; Wsol et al., 2004). In vivo, this normally occurs with the assistance of an enzyme catalyst.

WebMay 1, 2004 · Chirality is a chemical term that means handedness. Although two chemical molecules may appear to have the same elements and similar properties, they can still have different structures. When two molecules appear identical and their structures differ only by being mirror images of each other, those molecules are said to have chirality. WebJan 23, 2024 · Chirality.

WebJul 1, 2024 · Tests for chirality (a) (Most reliable) Check to see if the molecule has a pair of non-superimposable mirror image forms. (b) (Nearly always works) Look for a mirror plane; if no mirror plane, the molecule is nearly always chiral (c) Look for chiral centers – tetrahedral atoms (usually carbon) with four different groups attached.

WebA mechanism for separating chiral molecules is proposed. The separation of two enantiomers in an aquifer is considered. The molecules are dragged in the aquifer porous medium by a flow of water or of another liquid. The molecule velocity is u=v/R, where v is the liquid velocity, and R is the retardation factor.
