| Research Abstract |
Production of an amino acid and various organic molecules were successful by shock experiments simulating meteorite ocean impact events. High productions of ammonia and hydrogen cyanide were confirmed by impact-plume-simulation experiments. Polymerization experiments of amino acids were also successful : successful polymerization of alanine and glycine at 5 GPa was surprising results. Best presentation awards were granted to this result. In addition, variety and unique peptides were formed under high pressure and temperature conditions.
