Fossilized lipids preserved in sedimentary rocks offer singular insights into the Earth's
palaeobiology. These 'biomarkers' encode information pertaining to the oxygenation of the …

▪ Abstract Our understanding of the evolution of organic molecules, and their voyage from
molecular clouds to the early solar system and Earth, has changed dramatically …

Abstract Principles of Stable Isotope Geochemistry is written as a textbook to accompany a
one semester course in Stable Isotope Geochemistry. There are 13 chapters, each dealing …

All terrestrial organisms depend on nucleic acids (RNA and DNA), which use pyrimidine and
purine nucleobases to encode genetic information. Carbon-rich meteorites may have been …

Numerous descriptions of organic molecules present in the Murchison meteorite have
improved our understanding of the early interstellar chemistry that operated at or just before …

Gas chromatographic-mass spectral analyses of the four stereoisomers of 2-amino-2, 3-
dimethylpentanoic acid (DL-α-methylisoleucine and DL-α-methylalloisoleucine) obtained …

Covering: 1950s to the present day The carbonaceous chondrite meteorites are fragments of
asteroids that have remained relatively unprocessed since the formation of the solar system …

Carbon-rich meteorites, carbonaceous chondrites, contain many biologically relevant
organic molecules and delivered prebiotic material to the young Earth. We present …

Many organic compounds or their precursorsfound in meteorites originated in the interstellar
or circumstellarmedium and were later incorporated intoplanetesimals during the formation …

Most of the carbon in carbonaceous chondrites is organic material that displays structures as
diverse as kerogen-like macromolecules and simpler soluble compounds ranging from polar …
