Evidence for Extraterrestrial Amino-acids and Hydrocarbons in the Murchison Meteorite
Organic molecules found in meteorites seem to have been formed before the meteorites reached Earth.

HCN: A plausible source of purines, pyrimidines and amino acids on the primitive earth
SummaryDilute (0.1M) solutions of HCN condense to oligomers at pH 9.2. Hydrolysis of these oligomers yields 4,5-dihydroxypyrimidine, orotic acid, 5-hydroxyuracil, adenine,Expand

Quantification of monocarboxylic acids in the Murchison carbonaceous meteorite
Although the nature and origin of carbon and its compounds in meteorites have been reviewed by Hayes1 and Nagy2, much of our understanding of carbon and its compounds in carbonaceous chondritesExpand

Evidence for the Presence of Low Molecular Weight Alcohols and Carbonyl Compounds in the Murchison Meteorite
Alcohols, aldehydes and ketones identified in the Murchison C2 chondrite include: methanol, ethanol, 2-propanol, butyl alcohols, formaldehyde, acetaldehyde, propionaldehyde, acetone, 2-butanone,Expand

Global N2O cycles--terrestrial emissions, atmospheric accumulation and biospheric effects.
Tropospheric nitrous oxide concentration has increased by 0.2-0.4% per year over the period 1975 to 1982, amounting to net addition to the atmosphere of 2.8-5.6 Tg N2O-N per year. This perturbation,Expand

Nonprotein amino acids in the murchison meteorite.
Twelve nonprotein amino acids appear to be present in the Murchison meteorite. The identity of eight of them has been conclusively established as N-methylglycine, beta-alanine, 2-methylalanine,Expand

Heterocyclic compounds recovered from carbonaceous chondrites
Abstract N-heterocyclic compounds were recovered from the Murchison, C2, Murray, C2, and Orgueil C1 carbonaceous chondrites. Combined gas chromatograpby-low resolution mass spectrometry and gasExpand

pH profile of the adsorption of nucleotides onto montmorillonite
The interaction of 5′-AMP with montmorillonite saturated with various ratios of two metals found ubiquitously on the surface of Earth, that is, iron and calcium, is investigated. Adsorption andExpand

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. For seven of the amino acids nearly equal amounts of the D and L isomers areExpand
