| Outline of Final Research Achievements |
The purposes of the present study are to perform various experiments for formations of prebiotic organic molecules. We consider that water-rock interaction on the early Earth (including meteorite impact, diagenesis of marine sediments etc.) had played important roles for the prebiotic organic formations. We performed simulating experiments for those water-rock interactions, besides installing state-of-art analytical instruments. We were successful to synthesize various amino acids, nucleic acids, and peptides under high P and T conditions. In addition, selective stabilization of ribose was successful in highly alkaline conditions. Those new data are valuable to promote our knowledge for origin of life.
