A Chemist’s Perspective on the Role of Phosphorus at the Origins of Life

open access: yesLife, 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 ...

Potential Role of Inorganic Confined Environments in Prebiotic Phosphorylation

open access: yesLife, 2018
A concise outlook on the potential role of confinement in phosphorylation and phosphate condensation pertaining to prebiotic chemistry is presented. Inorganic confinement is a relatively uncharted domain in studies concerning prebiotic chemistry, and ...

Step by Step Strecker Amino Acid Synthesis from Ab Initio Prebiotic Chemistry.

open access: yesJournal of Physical Chemistry Letters, 2021
The amino acids synthesis from elementary precursors in abiotic conditions is traditionally described according to the Strecker reaction, thoroughly invoked to justify the observation of amino acids in extraterrestrial samples and their emergence in the ...

Organic compounds in fluid inclusions of Archean quartz-Analogues of prebiotic chemistry on early Earth. [PDF]

open access: yesPLoS ONE, 2017
The origin of life is still an unsolved mystery in science. Hypothetically, prebiotic chemistry and the formation of protocells may have evolved in the hydrothermal environment of tectonic fault zones in the upper continental crust, an environment where ...

Scum of the Earth: A Hypothesis for Prebiotic Multi-Compartmentalised Environments

open access: yesLife, 2021
Compartmentalisation by bioenergetic membranes is a universal feature of life. The eventual compartmentalisation of prebiotic systems is therefore often argued to comprise a key step during the origin of life.

A prebiotic chemistry inspired one-step functionalization of zwitterionic nanofiltration membranes for efficient molecular separation

open access: yesJournal of Membrane Science Letters, 2022
Loose nanofiltration (LNF) membranes have shown promises in achieving efficient separation on molecular level at relatively low pressure. In this study, a zwitterionic PES/AMN/PSBAE LNF membrane was designed by co-depositing the AMN and an in-house made ...

Comprehensive Mapping of Compositional Dynamics in the Formose Reaction Network

open access: yesAngewandte Chemie, EarlyView.
Mass spectrometric mapping of target and non‐target products in the formose reaction network was achieved using van Krevelen diagrams and Kendrick mass defect plots. The developed visualization framework offers a powerful means to guide rational strategies for reaction control.

prebiotic phosphorus chemistry reconsidered

open access: yesOrigins 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.

Spontaneous formation and base pairing of plausible prebiotic nucleotides in water

open access: yesNature 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
