Prebiotic Photoredox Synthesis from Carbon Dioxide and Sulfite [PDF]
, 2021 Carbon dioxide (CO2) is the major carbonaceous component of many planetary atmospheres including the Earth throughout its history, and prebiological chemistry that reduces this C1 feedstock to organics has accordingly been sought.

Did minerals perform prebiotic combinatorial chemistry? [PDF]
, 1996 It has long been suspected that mineral surfaces may have been important in prebiotic chemistry. The recent demonstrations of extended oligomerization of nucleotides, amino acids and carbohydrates on mineral surfaces add support to the potential ...

Radicals in prebiotic chemistry
Pure and Applied Chemistry, 2020 Abstract Radical chemistry is tightly interwoven in proposed prebiotic synthetic pathways, reaction networks and geochemical scenarios that have helped shape our understanding of how life could have originated. Gas-phase prebiotic reactions involving electric discharge, vapour ablation by asteroidal and cometary impacts as well as ...

Spontaneous formation and base pairing of plausible prebiotic nucleotides in water
Nature Communications, 2016 One of the questions for prebiotic chemistry is the formation of complementary base pairing systems. Here, the authors show that plausible two prebiotic heterocycles can form glycosidic bonds with ribose in water and that these spontaneously base-pair in

Prebiotic Access to Enantioenriched Amino Acids via Peptide-Mediated Transamination Reactions [PDF]
, 2023 The kinetic resolution of racemic amino acids mediated by dipeptides and pyridoxal provides a prebiotically plausible route to enantioenriched proteinogenic amino acids.

Abiotic and prebiotic phosphorus chemistry [PDF]
, 2011 The chief obstacle to understand the metabolic origin of life or RNA-based life is to identify a plausible mechanism for overcoming the clutter wrought by abiotic chemistry.

A Model Study on the Dynamics of the Amino Acid Content in Micrometeoroids during Atmospheric Entry
Chemistry, 2020 A model for the survival of the amino acid content in micrometeorites and its possible transformations upon atmospheric entry is described. Since any organic species released in the atmosphere at high altitudes would exhibit a limited lifetime with ...

Open questions in understanding life’s origins
Communications Chemistry, 2021 The chemical space of prebiotic chemistry is extremely large, while extant biochemistry uses only a few thousand interconnected molecules. Here we discuss how the connection between these two regimes can be investigated, and explore major outstanding ...

prebiotic phosphorus chemistry reconsidered
Origins of life and evolution of the biosphere, 1997 The available evidence indicates that the origin of life on Earth certainly occurred earlier than 3.5 billion years ago and perhaps substantially earlier. The time available for the chemical evolution which must have preceded this event is more difficult to estimate.
