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.
