The distribution and isotopic and enantiomeric compositions of amino acids found in three distinct fragments of the Tagish Lake C2-type carbonaceous chondrite were investigated via liquid chromatography with fluorescence detection and time-of-flight mass spectrometry and gas chromatography isotope ratio mass spectrometry. Large l-enantiomeric excesses (lee 43-59%) of the a-hydrogen aspartic and glutamic amino acids were measured in Tagish Lake, whereas alanine, another a-hydrogen protein amino… Expand

Enrichment of the amino acid l-isovaline by aqueous alteration on CI and CM meteorite parent bodies
TLDR
The large asymmetry in isovaline and other α-dialkyl amino acids found in altered CI and CM meteorites suggests that amino acids delivered by asteroids, comets, and their fragments would have biased the Earth's prebiotic organic inventory with left-handed molecules before the origin of life. Expand
Isotopic evidence for extraterrestrial non- racemic amino acids in the Murchison meteorite
TLDR
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. Expand

Distribution and stable isotopic composition of amino acids from fungal peptaibiotics: assessing the potential for meteoritic contamination.
TLDR
It is shown that the relatively simple distribution of the C(4) and C(5) amino acids in fungal peptides is distinct from the complex distribution observed in many carbonaceous chondrites, and potentially diagnostic relationships between the stable isotopic compositions of pairs of amino acids from the fungan peptides that may aid in ruling out fungal contamination as a source of meteoritic amino acids.

Enantiomeric Excesses in Meteoritic Amino Acids
TLDR
Gas chromatographic-mass spectral analyses of the four stereoisomers of 2-amino-2,3-dimethylpentanoic acid obtained from the Murchison meteorite show that the L enantiomer occurs in excess, indicative of an asymmetric influence on organic chemical evolution before the origin of life. Expand
