Chirality
Chirality is the geometric property of a molecule or object that is non-superimposable on its mirror image, analogous to left and right hands, and is a fundamental organizing principle of biological and chemical systems.
Overview
Louis Pasteur first recognized molecular chirality in 1848 by manually separating two tartrate crystal forms that rotated polarized light in opposite directions. Biological systems are inherently chiral: all natural amino acids are left-handed and all biological sugars are right-handed — an asymmetry that shapes the chemistry of every living cell and influences how molecules interact with chiral receptor sites.
Why it matters
The thalidomide tragedy demonstrated the profound medical stakes of chirality: one enantiomer treated morning sickness while the other caused severe birth defects, transforming how pharmaceutical development handles chiral compounds and driving modern chiral synthesis and resolution techniques. Chirality also connects chemistry to deep questions in physics about symmetry violation and the origins of biological homochirality.
