Photochirogenesis: Photochemical Models on the Origin of Biomolecular Homochirality

摘要: Current research focuses on a better understanding of the origin biomolecular asymmetry by identification and detection possibly first chiral molecules that were involved in appearance evolution life Earth. We have reasons to assume these specific amino acids. Chiral acids been identified both chondritic meteorites simulated interstellar ices. Present circularly polarized electromagnetic radiation was environments an asymmetric photon-molecule interaction might triggered symmetry breaking. review possible prebiotic ‘chiral photons’ form light, with early organic molecules. will highlight recent studies enantioselective photolysis racemic light experiments photochemical synthesis from only one C N containing simulating environments. Both approaches are based circular dichroic transitions be presented as well.
