Why is chirality so important? Chirality is a particularly important concept in biology, because cells are mostly composed of chiral molecules.
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. flag of listenbourgWebChiral molecules contain one or more chiral centers, which are almost always tetrahedral ( sp3 -hybridized) carbons with four different substituents.
