ABSTRACT: This study investigates prebiotic chemistry on Titan and Early Earth using experimental methods, including Differential Scanning Calorimetry (DSC) and Fourier-Transform Infrared Spectroscopy (FTIR), which are relevant for identifying molecular structures and thermal stability of amino acids. Analyses of glycine and acetonitrile with calcium carbonate under UV-C radiation show that glycine oligomers facilitate stable amino acid synthesis. We conclude that Titan’s environment can directly support the formation of life-relevant molecules, revealing a plausible pathway for chemical evolution analogous to that on Early Earth.
