Amino-acids, Aliphatic and Aromatic Hydrocarbons in the Murchison Meteorite
TLDR
The Murchison meteorite, a type III carbonaceous chondrite, contains substantial amounts of amino-acids, predominantly cyclic aliphatic hydrocarbons, which are consistent with the appreciable content of carbon and nitrogen of this meteorite.Abstract:

The Hypercycle: A principle of natural self-organization Part C: The realistic hypercycle
Manfred Eigen,Peter Schuster +1 more
TL;DR: Topologic methods are used to characterize a particular class of self-replicative reaction networks: the hypercycles, and hypercyclic organization proves to be a necessary prerequisite for maintaining the stability of information and for promoting its further evolution.

Organic compounds in carbonaceous meteorites
TL;DR: Structural and stable isotopic characteristics suggest that a number of environments may have contributed to the organic inventory, including interstellar space, the solar nebula and the asteroidal meteorite parent body.

TL;DR: The results demonstrate that the purines detected in meteorites are consistent with products of ammonium cyanide chemistry, which provides a plausible mechanism for their synthesis in the asteroid parent bodies, and strongly supports an extraterrestrial origin.

Organic matter in meteorites: molecular and isotopic analyses of the Murchison meteorite.
John R. Cronin,Sherwood Chang +1 more
TL;DR: The organic chemistry of carbonaceous chondrites is consistent with a formation scheme in which a parent body was formed from volatile-rich icy planetesimals containing interstellar organic matter, and warming of the parent body led to an extensive aqueous phase in which the interstellar organics underwent various reactions, and residual volatiles were largely lost leaving behind the suite of nonvolatile compounds that now characterize these meteorites as discussed by the authors.

Amino acids in meteorites
John R. Cronin,Sandra Pizzarello +1 more
TL;DR: The Murchison meteorite has recently been the major source of new naturally-occurring amino acids, and thirty three of these amino acids are unknown in natural materials other than carbonaceous chondrites.

TL;DR: Meteoritic organic chemical analyses since 1900, considering volatile materials distribution and carbonaceous chondrites as discussed by the authors, have been carried out for meteoritic organic chemistry analyses, with a focus on carbon dioxide.
