Research Abstract |
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.
