Prebiotic Chemistry: Geochemical Context and Reaction Screening [PDF]
Life, 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 ...

Prebiotic chemistry: A fuzzy field [PDF]
Comptes Rendus. Chimie, 2010 If prebiotic chemistry is defined as the study of the chemical steps, which lead to the first organisms, a clear-cut definition of “living organism” is needed. Unfortunately, no unambiguous and universally accepted definition exists for the concept “living”.

The origin of life and the prebiotic chemistry
Semina: 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]
Life, 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 ...

The protometabolic nature of prebiotic chemistry.
Chem Soc Rev, 2023 This tutorial review revises the main synthetic pathways of prebiotic chemistry, suggesting how they could be wired through common intermediates and catalytic cycles, as well as the boundary conditions under which they would become protometabolic.
