Abiotic synthesis of amino acids by x-ray irradiation of simple inorganic gases

Authors: Jun-ichi Takahashi, Teruo Hosokawa, Hitomi Masuda, Takeo Kaneko, Kensei Kobayashi, Takeshi Saito, Yuichi Utsumi 1–2 keV x-ray irradiation was carried out using a synchrotron radiation source on simulated primitive earth environment: a gas mixture of carbon monoxide, nitrogen, and water at atmospheric pressure. High-speed liquid chromatography of the hydrolyzed product solution detected amino acids. The amount of amino acids…
