A mixture of gases roughly simulating the primitive terrestrial atmosphere has been subjected to shock heating followed by a rapid thermal quench. Under strictly homogeneous conditions there is a very high efficiency of 5 x 1010 molecules per erg of shock-injected energy for production of alpha-amino acids. Calculations suggest that rapid quenching bypasses the usual thermochemical barrier. The product of energy flux and efficiency implies the unexpected conclusion that shocks occurring on… 
Shock synthesis of amino acids II
TLDR
Thunder shock waves were shown to be a suitable source of energy for the production of amino acids and a combined gas chromatograph-mass spectrometer analysis of the reaction product showed identical amounts of D and L amino acids, thus confirming the absence of contaminants.
Abiotic synthesis of amino acids and imidazole by proton irradiation of simulated primitive earth atmospheres
Proton irradiation of simulated primitive earth atmosphere was performed, and amino acids and imidazole were analyzed. A mixture of carbon monoxide and nitrogen over water was irradiated by high
Origin of organic compounds on the primitive earth and in meteorites
SummaryThe role and relative contributions of different forms of energy to the synthesis of amino acids and other organic compounds on the primitive earth, in the parent bodies or carbonaceous
Amino acids on the rampant primordial Earth: Electric discharges and the hot salty ocean
TLDR
In this work, the plausibility of one particularly important branch of prebiotic chemistry, the formation of amino acids, by electric discharge in a neutral atmosphere composed of carbon dioxide, nitrogen, and water vapour above liquid water, is investigated.
Shock Processing of Amino Acids Leading to Complex Structures—Implications to the Origin of Life
TLDR
It is reported, for the first time, that shock processed amino acids tend to form complex agglomerate structures that suggest that the building blocks of life could have self-assembled not just on Earth but on other planetary bodies as a result of impact events.
Long-Wavelength Ultraviolet Photoproduction of Amino Acids on the Primitive Earth
TLDR
Hydrogen sulfide is the initial photon acceptor in this work; superthermal atomic hydrogen photodissociation products appear to initiate reactions leading to amino acid synthesis with an overall quantum yield on the order of 5X10-5.
Formation of Ammonia and Organic Molecules by Oceanic Impact of Meteorite
High-pressure and high-temperature reactions in meteorite impact events were subjected to extensive research in order to resolve origin of organic molecules on the early Earth. In this article, I
