Abstract
A selection of amino acids, namely arginine, proline and tyrosine previously irradiated to 3.2 mega-Gray in the solid state and analyzed by differential scanning calorimetry (DSC) and optical rotatory dispersion (ORD) were analyzed in the present work by mass spectrometry with the purpose to identify the radiolysis products and validate the results obtained previously with DSC and ORD. The radiolysis of amino acids is a top-down approach of a research program designed to assess the radiolysis resistance of these molecules for 4.6 × 109 years once buried in primitive bodies of the Solar System.
