生命の起源を探るための有機化合物生成宇宙曝露実験 Cosmic Exposure Experiment for Study of Origins of Life セイメイ ノ キゲン オ サグル タメノ ユウキ カゴウブツ セイセイ ウチュウ バクロ ジッケン 三田, 肇 中山, 美紀 白水, まどか 中川, 和道 Exposure experiment amino acid peptide Exposure experiment amino acid peptide application/pdf 論文(Article) Second space exposure experiment “TANPOPO 2” on the International Space Station was planned for study of origin of life. Authors were tried to synthesis peptides those are condensation products of amino acids, because peptides syntheses are the most important step for the producing proteins on the primitive Earth before the first life aperance. Although, in our preliminary experiments in the first space exposure experiment “TANPOPO”, authors found dialanine that is a dipeptide from amino acid, alanine, the experimental result was not enough to conclude peptide formed in the space. Therefore, precise experiments were planned in the “TANPOPO2”. Stable isotope labeled alanine was used for preventing the biological contamination, three different patterns of amino acids were chosen to conclude wide variety peptides formation. In this experiment, thin film formation apparatus using vaporization of amino acids, spectrometry of vacuum ultraviolet adsorption were prepared for the space experiment. And the space exposure experiment was started from August, 2019. 福岡工業大学総合研究機構 2020-04-01 jpn departmental bulletin paper VoR http://hdl.handle.net/11478/1493 https://fit.repo.nii.ac.jp/records/541 24345725 福岡工業大学総合研究機構研究所所報 2 115 118 https://fit.repo.nii.ac.jp/record/541/files/11478-1493_p115.pdf application/pdf 1.1 MB 2020-09-14
