| Research Abstract |
It is considered that a first living organisms had been emerged under hydrothermal conditions on the primitive earth. However, the mechanism how biologically important organic compounds, such as proteins, had formed under such conditions was not clearly described. Here, the hydrothermal flow reactor technology, which was established in our group, was improved and a new monitoring method was successfully developed for simulating the hydrothermal vent system as a realistic model. By using this method, the activities of naturally occurring minerals for the peptide formation reaction, which was discovered in our group at 2005, were analyzed and we found the fact that carbonate minerals possess enhancement activities for the peptide formation.
