...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...

... valuable insights into paleoecology and may play a key role in prebiotic chemistry. Despite their significance in nature, understanding the conditions underlying the formation of fulgurites poses severe challenges, as the physical parameters and timing of the fulgurite-generating lightning event still need...

... 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. Two deposition procedures have been used: Chemical Vapor Deposition (CVD) ( Lomenech et al. , 2005 ) and selective adsorption from water solutions ( Meng et al. , 2004 ). In the CVD-type procedure, an appropriate amount of amino acid...

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...

... of proteins ( Martins et al. 2013 ). Chyba and Sagan (1992) argued that a major role of meteorites in influencing the prebiotic chemistry of the early Earth was not necessarily the delivery of whole material, but instead the addition of energy in the Earth’s upper atmosphere. When asteroidal particles...

... stabilization of ribose by borate in prebiotic Earth might explain why ribose became the sugar component in nucleic acids. The authors thank Steven A. Benner and Hyo-Joong Kim for fruitful discussions on prebiotic chemistry. We also thank Edward Grew, Nils Holm, and Romulus Scorei for helpful comments...

... in this field, more collaborations between the researchers are needed. As our understanding of prebiotic chemistry and geology broadens, it becomes clear that a resolution of the question of how protocells arose will not come from a single field, but rather from a concerted effort at the interface between...
