Journal ArticleDOI
Ribose and related sugars from ultraviolet irradiation of interstellar ice analogs
Cornelia Meinert,Iuliia Myrgorodska,Pierre de Marcellus,Thomas Buhse,Laurent Nahon,Søren Vrønning Hoffmann,Louis Le Sergeant d'Hendecourt,Uwe J. Meierhenrich +7 more
TL;DR: The detection of ribose provides plausible insights into the chemical processes that could lead to formation of biologically relevant molecules in suitable planetary environments and suggests that the generation of numerous sugar molecules, including the aldopentose ribose, may be possible from photochemical and thermal treatment of cosmic ices in the late stages of the solar nebula.
Journal ArticleDOI
Non-racemic amino acid production by ultraviolet irradiation of achiral interstellar ice analogs with circularly polarized light
Pierre de Marcellus,Cornelia Meinert,Michel Nuevo,Jean-Jacques Filippi,Grégoire Danger,D. Deboffle,Laurent Nahon,Louis D'Hendecourt,Uwe J. Meierhenrich +8 more
TL;DR: In this paper, the first abiotic cosmic ice simulation experiments that produce species with enantiomeric excesses (e.g., 1.34% for (13C)-alanine) were reported.
Journal ArticleDOI
Aldehydes and sugars from evolved precometary ice analogs: Importance of ices in astrochemical and prebiotic evolution
Pierre de Marcellus,Cornelia Meinert,Iuliia Myrgorodska,Laurent Nahon,Thomas Buhse,Louis D'Hendecourt,Uwe J. Meierhenrich +6 more
TL;DR: The importance of detecting aldehydes and sugars in extraterrestrial environments, in the gas phase of hot molecular clouds, and, more importantly, in comets and in primitive meteorites that have most probably seeded the Earth with organic material as early as 4.2 billion years ago is pointed out.
Journal ArticleDOI
Enantiomeric Excesses Induced in Amino Acids by Ultraviolet Circularly Polarized Light Irradiation of Extraterrestrial Ice Analogs: A Possible Source of Asymmetry for Prebiotic Chemistry
Paola Modica,Cornelia Meinert,Pierre de Marcellus,Laurent Nahon,Uwe J. Meierhenrich,Louis D'Hendecourt +5 more
TL;DR: In this article, the authors performed the asymmetric synthesis of amino acids on achiral extraterrestrial ice analogs by VUV CPL, investigating the chiral asymmetry transfer at two different evolutionary stages at which the analogs were irradiated (regular ices and/or organic residues) and at different photon energies (6.6 and 10.2 eV).
Journal ArticleDOI
Photonenergy‐Controlled Symmetry Breaking with Circularly Polarized Light
Cornelia Meinert,Søren Vrønning Hoffmann,Patrick Cassam-Chenaï,Amanda C. Evans,Chaitanya Giri,Laurent Nahon,Uwe J. Meierhenrich +6 more
TL;DR: Stereocontrol provides novel insights into the wavelength and polarization dependence of asymmetric photochemical reactions and are highly relevant for absolute asymmetric molecular synthesis and for understanding the origins of homochirality in living matter.
