High sensitive enantiomeric analysis of bioorganic compounds for cosmic samples

氨基酸的同源性起源是生命起源研究的重要课题之一。最近，人们认为在空间环境中实现了同色化。为了证实这一假设，需要在宇宙尘埃等空间样品中测定少量的氨基酸对映体比率。因此，我们开发了一种高灵敏度的对映体分析系统，并对极小颗粒的碳质球粒陨石进行了分析。

Origin of homochirality of amino acids is one of the most important subjects for origins of life. Recently, it is thought that homochirality was achieved in the space environment. In order to confirm this hypothesis, small amount of enantiomeric ratio of amino acids should be determined in the space samples e.g. cosmic dusts. Therefore, we developed a high sensitive enantiomeric analysis system and demonstrated a analysis of very small particle of carbonaceous chondrite.
