This work examines potential synthetic routes of glycine and methylamine from a common set of precursors present in carbonaceous chondrite meteorites, using data from laboratory analyses of the well-studied CM2 meteorite Murchison and aims to contextualize the current knowledge about gas-phase reactions and irradiated ice grain chemistry for the synthesis of these species through parent body processes.

Unusual stable isotope ratios in amino acid and carboxylic acid extracts from the Murchison meteorite
- Environmental ScienceNature
- 1987
The isotopic composition of hydrogen, nitrogen and carbon in amino acid and monocarboxylic acid extracts from the Murchison meteorite confirms the extraterrestrial origin of both classes of compound, and provides the first evidence suggesting a direct relationship between the massive organo-synthesis occurring in interstellar clouds and the presence of pre-biotic compounds in primitive planetary bodies.

The results suggest the possibility that the production mechanisms for hydrocarbons and carboxylic acids may be similar and impose constraints on the identity of the reactant species, and are consistent with the kinetically controlled synthesis of higher homologues from lower ones.

Carbon isotope composition of individual amino acids in the Murchison meteorite

The amino acids in the Murchison meteorite are enriched in 13C, indicating an extraterrestrial origin, and Alanine is not racemic, and the 13C enrichment of its D- and L-enantiomers implies that the excess of the L- enantiomer is indigenous rather than terrestrial contamination, suggesting that optically active materials were present in the early Solar System before life began.

It is shown that individual amino-acid enantiomers from Murchison are enriched in 15N relative to their terrestrial counterparts, so confirming an extraterrestrial source for an L-enantiomer excess in the Solar System that may predate the origin of life on the Earth.
