Prebiotic chemistry: From dust to molecules and beyond
2022Prebiotic chemistry has dominated the origins of life (OoL) field to such an extent that often these terms have been used interchangeably. While prebiotic chemistry has benefited from cross-seeding with other disciplines (e.g., biochemistry, biophysics, computational sciences, geosciences), the OoL problem is still primarily a chemical one.

Journal of Molecular Evolution, 1991
In the traditional concept for the origin of life as proposed by Oparin and Haldane in the 1920s, prebiotic reactants became slowly concentrated in the primordial oceans and life evolved slowly from a series of highly protracted chemical reactions during the first billion years of Earth's history.

The prebiotic chemistry of nucleotides
Origins of Life, 1984Diiminosuccinonitrile (DISN), formed by the oxidation of diaminomaleonitrile (DAMN), has been investigated as a potential prebiotic phosphorylating agent. DISN effects the cyclization of 3'-adenosine monophosphate to adenosine 2', 3'-cyclic phosphate in up to 39% yield. The mechanism of this reaction was investigated.

Prebiotic-like chemistry on Titan
Chemical Society Reviews, 2012Titan, the largest satellite of Saturn, is the only one in the solar system with a dense atmosphere. Mainly composed of dinitrogen with several % of methane, this atmosphere experiences complex organic processes, both in the gas and aerosol phases, which are of prebiotic interest and within an environment of astrobiological interest.

The cometary contribution to prebiotic chemistry
Advances in Space Research, 1992Different estimates based on dynamical considerations, lunar cratering rates, Solar System chemical abundances, and the single-impact theory on the origin of the Earth-Moon system suggest that comets and other related small, volatile-rich primitive minor bodies captured by the Earth during the early Archean must have been a major source of volatiles on

Meteorites as Catalysts for Prebiotic Chemistry
Chemistry – A European Journal, 2013OH (2:1 v/v), and sulfu-ric acid. In the case of chondrites, achondrites, and stony-iron meteorites, the samples were also pyrolyzed at 6008C.After the treatment, the powders did not release any traceof organic substances. The synthesis of large number of com-pounds was observed (Scheme 1): nucleobases and their an-alogues, carboxylic acids, amino ...

Rooting Prebiotic Chirality in Spinomeric Chemistry?
Astrobiology, 2009Spinomeric chemistry is a domain of physical chemistry that explores the role of spin-isomery in chemical reactivity. In large magnetic fields (B), chemical structures with three adjacent nuclear spins (such as H(2)(17)O, H(2)(33)S,-NH(2), and and -(13)CH(2)-) form complex spinomers.

Mechanistic possibilities in prebiotic thiophosphate chemistry
Journal of Molecular Evolution, 1978Two types of reactivities of thiophosphates have been demonstrated: one being nucleophilic displacement by the P-S moiety of nucleoside phosphorothioates and the other, phosphorylation via P-S cleavage as the driving force. We have designed a system where both displacement on carbon and P-S cleavage are possible.

Fluid flow fosters prebiotic chemistry
C&EN Global Enterprise, 2017When it comes to understanding the origins of life, scientists have already determined that biochemical building blocks—amino acids, nucleobases, and sugars—can form under early-Earth-like conditions. But figuring out how those simple species combined in a dilute solution to form complex macromolecules has been harder.
