• A Combined Experimental and Theoretical Study on the Formation of the Amino Acid Glycine (NH2CH2COOH) and Its Isomer (CH3NHCOOH) in Extraterrestrial Ices (2005, background): “Munoz Caro et al. (2002) investigated the irradiation of a mixture of water (H2O), methanol (CH3OH), ammonia (NH3), carbon monoxide (CO), and carbon dioxide (CO2) with a photon flux of 1:5 ; 10 15 s 1 for 24 hr and found that detectable quantities of amino acids were produced.”
• UV-photoprocessing of interstellar ice analogs: New infrared spectroscopic results (2003, background): “Less abundant residue species, like amino acids (Bernstein et al. 2002; Muñoz Caro et al. 2002), would be even more difficult to observe.”
• Interstellar Ice: The Infrared Space Observatory Legacy (2004, background): “…searches have focused on the gas phase (see Snyder 1997 for a review), but recent work has emphasized the possibility that they might be a minor constituent of ices that have been subjected to UV INTERSTELLAR ICE 61No. 1, 2004 photolysis (Bernstein et al. 2002; Munoz Caro et al. 2002; Woon 2002).”
• A THREE-PHASE CHEMICAL MODEL OF HOT CORES: THE FORMATION OF GLYCINE (2013, background): “…laboratory experiments have shown success in producing glycine and other amino acids by the photolysis of organic ice mixtures (Bernstein et al. 2002; Muñoz Caro et al. 2002; Holtom et al. 2005; Elsila et al. 2007), gas-phase mechanisms for amino-acid production have also been considered.”
• Complex organic molecules in protoplanetary disks (2013, background): “Multiple routes to the formation of glycine (and other simple amino acids) under interstellar conditions have been proposed including via Strecker synthesis (see, e.g., Peltzer et al. 1984), UV-irradiated ice mantles (see,e.g., Bernstein et al. 2002; Muñoz Caro et al. 2002), and gas-phase chemistry ”
• Amino Acids and the Asymmetry of Life (2013, background): “Astonishingly, we identified the formation of 16 different amino acids in the interstellar ice analogues.(3) Amino acids such as glycine, alanine, valine, proline, aspartic acid, and serine were detected.”
• Ice structures, patterns, and processes: A view across the icefields (2012, background): “Muñoz Caro et al. (2002) report the discovery of amino acids in ice made to mimic cometary ices from CO, CO2, NH3, and H2O; another paper by the same group describes the finding of diamino acids in the Murchison meteorite (Meierhenrich et al., 2004).”
• NON-RACEMIC AMINO ACID PRODUCTION BY ULTRAVIOLET IRRADIATION OF ACHIRAL INTERSTELLAR ICE ANALOGS WITH CIRCULARLY POLARIZED LIGHT (2011, result): “…up to 16 different amino acids has been reported in one experiment including achiral (glycine, sarcosine, β-alanine) and chiral amino acids (alanine, serine, aspartic acid, etc.; Muñoz Caro et al. 2002), and confirmed in several other similar experiments (Bernstein et al. 2002; Nuevo et al. 2008).”
• Mechanisms of Amino Acid Formation in Interstellar Ice Analogs (2007, background): “This observation is in agreement with previous labo ratory experiments in which amino acids have been made from several different ice compositions (Bernstein et al. 2002; Muñoz Caro et al. 2002; Holtom et al. 2005).”
• Erratum: Detection of amino acetonitrile in Sgr B2(N) (2008, methodology): “Amino acids were successfully produced in the laboratory by UV-photolysis of ice mixtures mimicking the mantles of insterstellar grains (Bernstein et al. 2002; Muñoz Caro et al. 2002).”
• Experimental evidence for glycolaldehyde and ethylene glycol formation by surface hydrogenation of CO molecules under dense molecular cloud conditions (2015, background): “Despite theoretical studies and laboratory-based work that show that glycine as well as several other amino acids should form in space (Muñoz Caro et al. 2002; Blagojevic, Petrie & Bohme 2003; Congiu et al. 2012; Garrod 2013), unambiguous detections are still lacking (Snyder et al. 2005).”
• Our astrochemical heritage (2012, background): “…the formation of organic species more complex than CH3OH (Gerakines et al. 1996; Bennett and Kaiser 2007; Öberg et al. 2009a, 2010b) up to amino acids (e.g., Bernstein et al. 2002; Muñoz Caro et al. 2002, 2004) and allow solid species to return into the gas phase (Öberg et al. 2009b, 2009c).”
