Outline of Final Research Achievements

Related with synthesis of amino acids in space, we have a hypothesis that a lot of amino acids are synthesized in a hot gas reactions, which are caused by a asteroid's impact onto a satellite/planet. In order to examine this hypothesis the impact experiment using a 2 staged gas gun has been carried out, where a accelerated projectile impacts on a target in nitrogen gas. By the impact a hot gas plume is generated and hot gas reactions take place during the cooling process. By analyzing the produced soot, it was confirmed that many kinds of amino acids were synthesized. By the isomer analysis, it was found that the sample contains more L-type (bio-type) amino acids than D-type acids. As generation of CN radicals is important in the hot gas reactions, we tried to make amino acids by the intermittent arc discharge method using nitrogen gas. As a result, we could confirm efficient synthesis of amino acids by this method.

Academic Significance and Societal Importance of the Research Achievements

生命の起源や宇宙科学と関連し、宇宙でどのように有機物が合成されて来たか解明することは、宇宙を知る上で重要である。ここでは、タイタン衛星などの衛星/惑星に小惑星が衝突し、衝突高温反応により種々のアミノ酸が合成され、蓄積されたという仮説を検証するため、模擬実験を行なった。その結果、予想通り、種々のアミノ酸が高効率に合成される事が示された。タイタン衛星に限らず、無数の衛星/惑星上で長期に渡りアミノ酸が合成され、蓄積されて来た事象を支持している。これらのアミノ酸の一部は、次のステップで重合を起こし、タンパク質の原型を作り出したと考えられ、生命の原材料が宇宙のいたる所で作られたと考えられる。
