A THREE-PHASE CHEMICAL MODEL OF HOT CORES: THE FORMATION OF GLYCINE (2013, methodology): “…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 the interstellar medium: IRAM 30 m line survey of Sagittarius B2(N) and (M) (2013, background): “The isotopic composition and racemic distribution of these amino acids, in particular, suggest that they, or at least their direct precursors, have an extrat rrestrial origin (see, e.g., Ehrenfreund et al. 2001; Bernsti et al. 2002; Elsila et al. 2007, and references therein).”
Erratum: Detection of amino acetonitrile in Sgr B2(N) (2008, background): “On the other hand, Elsila et al. (2007) experim nted the UV-photolysis of an ice mixture of H2O, CH3OH, HCN, and NH3, and found with isotopic labeling techniques multiple pathways leading to the formation of amino acids.”
Back to the Moon: The scientific rationale for resuming lunar surface exploration (2012, background): “…may be important for producing organic molecules in the icy mantles of interstellar dust grains, and on the surfaces of outer Solar System satellites and comets (e.g. Bernstein et al., 2002; Elsila et al., 2007), but the lunar poles are much more accessible than any of these other locations.”
Cometary glycine detected in samples returned by Stardust (2009, background): “Complex organics including amino acids can be readily formed in laboratorysimulated interstellar/cometary ices by UV or proton irradiation of ice mixtures that have been observed in comets and the ISM (Bernstein et al. 2002; Elsila et al. 2007; Hudson et al. 2008).”
