Nonracemic isovaline in the Murchison meteorite : Chiral distribution and mineral association
- S. Pizzarello, M. Zolensky, K. Turk
- Chemistry
- 15 April 2003
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. l… Expand

The Organic Content of the Tagish Lake Meteorite
- S. Pizzarello, Y. Huang, +4 authors M. Williams
- Chemistry, Medicine
- Science
- 23 August 2001
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 of… Expand
Molecular and compound-specific isotopic characterization of monocarboxylic acids in carbonaceous meteorites
- Y. Huang, Y. Wang, +4 authors S. Pizzarello
- Chemistry
- 15 February 2005
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 examined… Expand
Deuterium fractionation: the Ariadne's thread from the precollapse phase to meteorites and comets today
- C. Ceccarelli, P. Caselli, +4 authors D. Semenov
- Physics
- 27 March 2014
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 together… Expand
Molecular asymmetry in extraterrestrial chemistry: Insights from a pristine meteorite
- S. Pizzarello, Y. Huang, M. R. Alexandre
- Chemistry, Medicine
- Proceedings of the National Academy of Sciences
- 11 March 2008
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 the… Expand
Nitrogen-containing compounds in two CR2 meteorites: 15N composition, molecular distribution and precursor molecules
- S. Pizzarello, W. E. Holmes
- Chemistry
- 1 April 2009
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. These… Expand
