Organic molecules found in meteorites seem to have been formed before the meteorites reached Earth. 
Occurrence and Significance of Formaldehyde in the Allende Carbonaceous Chondrite
Meteorites may disperse formaldehyde to planets where, in the proper conditions, the compound could then serve as a precursor for carbohydrates.

Shock synthesis of amino acids from impacting cometary and icy planet surface analogues
Comets harbour the organic precursors of amino acids. High-velocity impact experiments into icy targets suggest that impacts involving icy planetary bodies could be a viable pathway to synthesize theExpand
Amino Acids Indigenous to the Murray Meteorite
Analysis of the Murray meteorite, a type II carbonaceous chondrite, has led to the identification of 17 amino acids that suggest that these amino acids are extraterrestrial in origin. Expand
Amino acids in a carbonaceous chondrite from Antarctica
The presence of both protein and non-protein amino acids and an equal abundance of D- and L-enantiomers of amino acids, is testimony to the extraterrestrial nature of these compounds. Expand

Organic Compounds in Meteorites
Organic compounds in meteorites seem to have formed by catalytic reactions of CO, H2, and NH3 in the solar nebula, at 360� to 400�K and (4 to 10) x 10-6 atm. The onset of these reactions wasExpand

Investigations of the Orgueil Carbonaceous Meteorite
Abstract The Orgueil meteorite consists of clay type minerals, carbonates, sulfates, iron oxides, elementary sulfur, and bituminous organic matter. It contains approximately 20 percent water, a partExpand
Racemization of Amino Acids in Sediments from Saanich Inlet, British Columbia
In sediments spanning the last 9000 years from Saanich Inlet L enantiomers of amino acids are most abundant, but the percentages of D enantiomers increase with age, apparently because of partialExpand

Endogenous Carbon in Carbonaceous Meteorites
Seven carbonaceous chondrites have been analyzed for soluble organic compounds, carbonate, and residual carbon, and these values are interpreted to indicate thatcarbonate, residualcarbon, and part of the extractable organic material are endogenous to these meteorites. Expand
