Chirality left right
WebChirality is commonly observed in nature and life, which exists at all length scales, from the molecular level (the single left- or right-handed amino acid) to the supramolecular level (the right-handed double helix of DNA), and up to macrobiomineralized materials (marine and snail shells) [314–317]. Chirality is a central theme in nature ... WebThe chirality of a particle is more abstract: It is determined by whether the particle transforms in a right- or left-handed representation of the Poincaré group. [a] For …
