There is little consensus regarding the plausibility of organic synthesis in submarine hydrothermal systems (SHSs) and its possible relevance to the origin of life. The primary reason for the persistence of this debate is that most experimental high temperature and high-pressure organic synthesis studies have neglected important geochemical constraints with respect to source material composition. We report here the results of experiments exploring the potential for amino acid synthesis at high…

Peptide concentrations estimated by the Lowry method were significantly higher when the mixture was heated at 300°C than those at lower temperatures, despite having more than 80% of the initial amino acids decomposed, and it was revealed that the peptides measured here were only part of the bonds in the heated products.

This study simulates the shock compression state of a meteorite impact for a model system composed of CO2, H2O, and metallic iron slab by ab initio molecular dynamics combined with multiscale shock technique, and clarifies possible elementary reaction processes up to production of organic compounds.
Impact-induced amino acid formation on Hadean Earth and Noachian Mars
- PhysicsScientific Reports
- 2020
The results indicate that hypervelocity impact was a source of amino acids on the Earth during the Hadean and potentially on Mars during the Noachian, as impact events locally form amino acids at the impact sites.
