Prebiotic Chemistry: Geochemical Context and Reaction Screening [PDF]

open access: yesLife, 2013
The origin of life on Earth is widely believed to have required the reactions of organic compounds and their self- and/or environmental organization. What those compounds were remains open to debate, as do the environment in and process or processes by ...

Can prebiotic systems survive in the wild? An interference chemistry approach [PDF]

open access: yesFrontiers in Earth Science, 2022
It is challenging to evaluate the relevance of any given chemical system or geological environment to the origin of life. At the same time, life is the product of prebiotic chemistry that took place in some environment.

Prebiotic Chemistry that Could Not Not Have Happened. [PDF]

open access: yesLife (Basel), 2019
We present a direct route by which RNA might have emerged in the Hadean from a fayalite–magnetite mantle, volcanic SO2 gas, and well-accepted processes that must have created substantial amounts of HCHO and catalytic amounts of glycolaldehyde in the Hadean atmosphere.

Do-Nothing Prebiotic Chemistry: Chemical Kinetics as a Window into Prebiotic Plausibility. [PDF]

open access: yesAcc Chem Res
Origin of Life research is a fast growing field of study with each year bringing new breakthroughs. Recent discoveries include novel syntheses of life's building blocks, mechanisms of activation and interaction between molecules, and newly identified environments that provide promising conditions for these syntheses and mechanisms.

The origin of life and the prebiotic chemistry

open access: yesSemina: Ciências Exatas e Tecnológicas, 2004
In the present paper, a historical view from Oparin-Haldane hypothesis to prebiotic chemistry is discussed. Several aspects of prebiotic chemistry are also discussed such as: environments where the abiotic synthesis of biomolecules and biopolymers could

Chemistry of Homocysteine Thiolactone in A Prebiotic Perspective [PDF]

open access: yesLife, 2019
Homocysteine is a non-proteinogenic sulfur-containing amino acid. Like cysteine, it can form disulfide bridges and complex metallic cations. It is also closely related to methionine, the first amino acid in the synthesis of all contemporary proteins ...

How Prebiotic Chemistry and Early Life Chose Phosphate [PDF]

open access: yesLife, 2019
The very specific thermodynamic instability and kinetic stability of phosphate esters and anhydrides impart them invaluable properties in living organisms in which highly efficient enzyme catalysts compensate for their low intrinsic reactivity ...

Harnessing prebiotic formamide chemistry: a novel platform for antiviral exploration [PDF]

open access: yesScientific Reports
Viruses and host cells are intricately connected through a shared “chemical language” that may trace back to the prebiotic chemistry of early Earth. In this study, we present an innovative platform for antiviral exploration inspired by this primordial ...

Prebiotic Chemistry in Nanoconfinement [PDF]

open access: yes, 2016
Water presents extremely different properties depending not only on conditions like temperature and pressure but also on the local environment (bulk vs. interfacial water), which in turn profoundly affects chemical reactions in solution. Here, we present the results of extensive ab initio molecular dynamics and metadynamics simulations in which we ...
