| Outline of Final Research Achievements |
We have established a new method to trace origins of organic molecules called "13C-13C Isotopologue analysis". The method precisely determine abundance of C-C bonding both consisting of the rare stable carbon isotope 13C. Especially, our experiments demonstrated that bio-synthetic ethanol and ethane show a specific 13C-13C abundance, which is markedly higher than those observed in non-biological molecules synthesized in laboratory and nature. Therefore, the new tracer is useful as a "biomarker" for distinguishing biological and non-biological molecules in wide range of environment.

| Academic Significance and Societal Importance of the Research Achievements |
本研究で確立した新しい分析手法は、様々な宇宙・惑星環境での低級有機分子が、生物過程で形成した分子であるか否かを判別するための強力な手段となることが期待でき、今後の太陽系探査等における研究展開が期待される。また同手法は環境中に存在する有機分子の由来を判別するためにも応用可能であり、今後の環境計測技術としての発展も期待できる。
