Nonracemic isovaline in the Murchison meteorite : Chiral distribution and mineral association
Abstract The enantiomeric and carbon-isotopic composition of the amino acid isovaline have been analyzed in several samples of the Murchison meteorite and one sample of the Murray meteorite. lExpand

Enantiomeric Excesses in Meteoritic Amino Acids
Gas chromatographic-mass spectral analyses of the four stereoisomers of 2-amino-2,3-dimethylpentanoic acid (DL-α-methylisoleucine and DL-α-methylalloisoleucine) obtained from the Murchison meteoriteExpand

The Organic Content of the Tagish Lake Meteorite
The Tagish Lake meteorite fell last year on a frozen lake in Canada and may provide the most pristine material of its kind. Analyses have now shown this carbonaceous chondrite to contain a suite ofExpand

Molecular and compound-specific isotopic characterization of monocarboxylic acids in carbonaceous meteorites
Abstract Low molecular weight monocarboxylic acids are the most abundant water soluble organic compounds in the Murchison and many other CM type carbonaceous chondrites. In this study, we examinedExpand

Deuterium fractionation: the Ariadne's thread from the precollapse phase to meteorites and comets today
The Solar System formed about 4.6 billion years ago from a condensation of matter inside a molecular cloud. Trying to reconstruct what happened is the goal of this chapter. For that, we put togetherExpand

Molecular asymmetry in extraterrestrial chemistry: Insights from a pristine meteorite
The nonracemic amino acids of meteorites provide the only natural example of molecular asymmetry measured so far outside the biosphere. Because extant life depends on chiral homogeneity for theExpand

Nitrogen-containing compounds in two CR2 meteorites: 15N composition, molecular distribution and precursor molecules
Abstract Amino acids, amines and aldehydes were obtained from the water extracts of two CR2 carbonaceous chondrites from Antarctica and analyzed for their molecular and 15 N isotopic content. TheseExpand

Radar-Enabled Recovery of the Sutter’s Mill Meteorite, a Carbonaceous Chondrite Regolith Breccia
The Meteor That Fell to Earth In April 2012, a meteor was witnessed over the Sierra Nevada Mountains in California. Jenniskens et al. (p. 1583) used a combination of photographic and video images ofExpand
