Photoionization of methanol: a molecular source for the prebiotic chemistry

, 2021
Methanol is one of the most abundant and ubiquitous molecules in the space. Its chemistry is fundamental to understand the molecular growing from prebiotic molecules, ions and radicals.

Sulfur Amino Acids: From Prebiotic Chemistry to Biology and Vice Versa

Synthesis, 2021
Two sulfur-containing amino acids are included in the list of the 20 classical protein amino acids. A methionine residue is introduced at the start of the synthesis of all current proteins.

Prebiotic chemistry in clouds

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, 1984
Diiminosuccinonitrile (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.

The cometary contribution to prebiotic chemistry

Advances in Space Research, 1992
Different 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

Materials Synthesis and Catalysis in Microfluidic Devices: Prebiotic Chemistry in Mineral Membranes

ChemCatChem, 2020
The processes that led to the origins of life possibly occurred in the inorganic precipitate membranes of alkaline hydrothermal vents. These geochemical systems provide spatial confinement, cross‐membrane gradients, and catalytic surfaces.

Meteorites as Catalysts for Prebiotic Chemistry

Chemistry – A European Journal, 2013
OH (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, 2009
Spinomeric 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, 1978
Two 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.

Adenine Adsorbed onto Montmorillonite Exposed to Ionizing Radiation: Essays on Prebiotic Chemistry

Astrobiology, 2020
Most adsorption and radiolysis experiments related to prebiotic chemistry studies are performed in distilled water or sodium chloride solutions. However, distilled water and sodium chloride solutions do not represent the composition of the primitive seas
