Chirality testing
WebChirality is an asymmetric quality that is relevant in many fields of science. The word chirality comes from the Greek (kheir), which means “hand,” a common chiral item. A chiral item or system is distinct from its mirror image; that is, it cannot be overlaid onto it. Golf clubs, scissors, shoes, and a corkscrew are examples of chiral ... WebChirality Testing. Chirality, a word derived from the Greek word “hand,” is a term used to describe the 3D orientation of a molecule. Just as you have two hands, chiral molecules exist in two forms, distinguished as either the right or the left hand. You may visualize this principle by looking at your hands; when placed side by side, they ...
