Traces of amino acid production recorded on the asteroid Ryugu ~Snapshot of water-organic reactions in the early solar system~
Summary
A research group of Assistant Professor Christian Potiszil of the Institute for Planetary Materials at Okayama University determined the concentration of amino acids contained in Ryugu particles collected from two different locations. The particles with more carbonate contained more of the amino acid dimethylglycine, while the amino acid dimethylglycine was not detected in the other particles. These results revealed that amino acids were formed on asteroids in the early solar system, and that water played an important role at this time.
These research results were published online in Nature Communications on March 17th.
