Formation of amino acids from models of Titan and more oxidized atmospheres

Abstract

Protein and non-protein amino acids were synthesized following hydrolysis of products obtained by high frequency discharge techniques applied to model atmospheres consisting of N2 as a nitrogen source together with CH4 and/or CO2 as a carbon source. Highest yields were obtained in the absence of CO2 and from mixtures rich in CH4. Amino acids would indeed be expected on the frozen surface of Titan with its CH4-N2 atmosphere.
