WebMay 1, 2004 · Chirality is probably one of the best scientific evidences we have against random chance evolution and chirality totally destroys the claim that life came from chemicals. Obviously, this is one fact they do not even want to discuss. Chirality is a chemical term that means handedness. Although two chemical molecules may appear to … WebChirality is a property of a molecule that results from its structure. Optical activity is a macroscopic property of a collection of these molecules that arises from the way they interact with light. Compounds, such as CHFClBr, that contain a single stereocenter are the simplest to understand.

• Any non-racemic chiral substance is called scalemic. Scalemic materials can be enantiopure or enantioenriched. • A chiral substance is enantiopure when only one of two possible enantiomers is present so that all molecules within a sample have the same chirality sense. Use of homochiral as a synonym is strongly discouraged.
