氨基酸是由一氧化碳、氮和水通过高能粒子（宇宙射线的成分）照射而形成的，这些物质可能是原始地球大气的成分。甘氨酸产率与沉积到气体混合物中的总能量成正比，并且当一氧化碳/氮气比为1时，其G值高达0.02。通过对原始地球大气中各种氨基酸合成能源有效能量的估算，认为宇宙射线是原始地球上氨基酸合成的重要能源之一。
Amino acids were formed from carbon monoxide, nitrogen and water, which are possible constituents of the primitive earth's atmosphere, by irradiation with high energy particles (components of cosmic rays). Glycine yield was proportional to the total energy deposited to the gas mixture, and its G-value was as high as 0.02 when the carbon monoxide/nitrogen ratio was 1. Based on an estimate of the effective energies of various types of energy sources available in the primitive earth's atmosphere for amino acid synthesis, it is suggested that cosmic rays were one of the most important energy sources for the synthesis of amino acids on the primitive earth.
