...Punam Dalai; Hussein Kaddour; Nita Sahai Abstract The onset of life on Earth was preceded by prebiotic chemistry in which complex organic molecules were formed from simpler ones in the presence of energy sources. These prebiotic organics were either synthesized on Earth itself (endogenously...

... at the beginning of life have spurred a number of experimental studies to investigate organic molecule adsorption, polymerization and catalytic reactions of relevance to prebiotic chemistry. This article reviews current ideas in how life originated, summarises experimental results and presents some of the existing...

... and degradation of fatty acids. Hydrogenation reactions were likely important for prebiotic chemistry on the early Earth, and today serve as one of the fundamental reaction classes that enable cellular life to construct biomolecules. An understanding and awareness of hydrogenation reactions is helpful...

... in metabolic pathways like respiration and the tricarboxylic acid cycle. Early life and prebiotic chemistry on Earth likely relied heavily upon the abiotic synthesis of carboxylic acids. Over time, life has diversified (de)carboxylation reactions and incorporated them into many facets of cellular metabolism...

... significance in the fields of biofilms and prebiotic chemistry. DFT calculations were performed for the glycine/silica system with the B3LYP functional with a 6–31++G** basis set, using the Gaussian 98 package. Additional theoretical details may be found in two recently published papers ( Lomenech et al...

Icons represent whether the signatures are primary prebiosignatures (species directly relevant for prebiotic chemistry), secondary prebio-signatures (species that are produced by events that are relevant for prebiotic chemistry, such as volcanism, lightning, impacts...

As our understanding of prebiotic chemistry and geology broadens, it becomes clear that a resolution of the question...

The formation of partially oxidized carbon species like alkane thiols, on the other hand, leaves open the possibility for much more interesting prebiotic chemistry.
