摘要: Left-right asymmetry is ubiquitous in nature. Recent studies reveal changes the energy and growth rate of crystal surfaces to which D or L amino acids bind, with binding itself being dictated by stereochemical matching. Likewise, oligomerization appears be a chiroselective process that enables propagation sequences defined handedness.[[For definition self-assembly, see: M. Bolli, R. Micura, A. Eschenmoser, Chem. Biol. 1997, 4, 309-320.]] These results, along related findings on symmetry breaking further amplification at supramolecular level, constitute new insights into origin homochirality living species.
