WebSep 22, 2024 · Nature through the looking glass. 09/22/20. By Oscar Miyamoto Gomez. Handedness—and the related concept of chirality—are double-sided ways of understanding how matter breaks symmetries. Our right and left hands are reflections of one another, but they are not equal. To hide one hand perfectly behind the other, we must … WebAbstract. Chirality plays a central role in the world around us, with nature and scientists producing an ever-increasing number of chiral molecules that have a wide range of different applications. The word chirality is used as a term to describe a molecule whose enantiomers are non-superimposable on their mirror images.

WebJul 11, 2024 · Chirality relates to the study of the three-dimensional structure of molecules. The term comes from the Greek root kheir-, hand, and means "handedness." Chiral molecules show left and right-handed nature in the sense that the molecules may exist as mirror-image forms that cannot be made to overlap by any amount of rotation.
