Enantiomeric Excesses in Meteoritic Amino Acids
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.
Organic matter in meteorites: molecular and isotopic analyses of the Murchison meteorite.
Carbonaceous chondrites comprise a unique subset of meteorites. Two classes of carbonaceous chondrites, the so-called CI1 and CM2 chondrites, are particularly interesting, in part because of their…

Isotopic analyses of nitrogenous compounds from the Murchison meteorite: ammonia, amines, amino acids, and polar hydrocarbons.

Amino Acid Analyses of the Murchison, Murray, and Allende Carbonaceous Chondrites
Three carbonaceous chondrites were examined for water-extractable amino acids. The Murchison Murray specimens were found to be of similar amino acid composition. This similarity suggests that these…
