The Effects of Iron on In Silico Simulated Abiotic Reaction Networks
Molecules, 2022 Iron is one of the most abundant elements in the Universe and Earth’s surfaces, and undergoes a redox change of approximately 0.77 mV in changing between its +2 and +3 states.

Phosphorus in prebiotic chemistry [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2006 The prebiotic synthesis of phosphorus-containing compounds—such as nucleotides and polynucleotides—would require both a geologically plausible source of the element and pathways for its incorporation into chemical systems on the primitive Earth. The mineral apatite, which is the only significant source of phosphate on Earth, has long been thought to be

A Chemist’s Perspective on the Role of Phosphorus at the Origins of Life
Life, 2017 The central role that phosphates play in biological systems, suggests they also played an important role in the emergence of life on Earth. In recent years, numerous important advances have been made towards understanding the influence that phosphates ...

Prebiotic Reaction Networks in Water
Life, 2020 A prevailing strategy in origins of life studies is to explore how chemistry constrained by hypothetical prebiotic conditions could have led to molecules and system level processes proposed to be important for life’s beginnings. This strategy has yielded

Potential Prebiotic Pathways in Titan’s Atmosphere: A Computational Exploration of HCN and NH3 Reactions [PDF]
, 2023 In this study, we explore the potential for prebiotic chemistry in Titan’s atmosphere through computational modeling of reactions involving hydrogen cyanide (HCN), hydrogen isocyanide (HNC), and ammonia (NH3).

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 ...
