Impacts of meteors have potentials to initiate chemical reactions between organics in meteors and its targets. In this study, we provided shock wave to the solution containes simple organics; formic acid and methylamine, in order to investigate weather meteor impacts generate any life's building blocks on the prebiotic Earth. We confirmed the formation of protein constituent amino acids, glycine and alanine. Formation of non protein constituent amino acids and amines were also confirmed. These resultd suggest that impact reactions might have generated part of organics in meteorites and supplied building brocks of life on the prebiotic Earth.

流星撞击有可能引发流星中的有机物与其目标之间的化学反应。在这项研究中，我们提供冲击波的解决方案包含简单的有机物;甲酸和甲胺，以调查天气流星的影响产生任何生命的基石上的前生物地球。我们证实了蛋白质组成氨基酸甘氨酸和丙氨酸的形成。还证实了非蛋白质组分氨基酸和胺的形成。这些结果表明，撞击反应可能在陨石中产生了部分有机物，并为生命起源前的地球提供了生命的建筑物。
