Sulfur Amino Acids: From Prebiotic Chemistry to Biology and Vice Versa
Synthesis, 2021Two 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.

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.

Study of Ferrocyanide Adsorption onto Different Minerals as Prebiotic Chemistry Assays
Astrobiology, 2021Considered one of the most promising building blocks of life on primitive Earth, cyanide and its complexes are likely to have played an important role in the emergence of life on the planet.

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.

Synthetic connectivity, emergence, and self-regeneration in the network of prebiotic chemistry
Science, 2020Mapping primordial reaction networks Chemists seeking to understand the origins of life have published a wide range of reactions that may have yielded the building blocks of proteins, nucleic acids, and lipids from simple precursors. Wołos et al. scoured

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

Materials Synthesis and Catalysis in Microfluidic Devices: Prebiotic Chemistry in Mineral Membranes
ChemCatChem, 2020The 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, 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.
