Emergence of homochirality in far-from-equilibrium systems: mechanisms and role in prebiotic chemistry.
TL;DR: The APED model is presented as the most natural realization of such thermodynamic openness and non-equilibrium, of recycling and of network autocatalysis, each of these in prebiotic conditions and the place and role of such self-structured networks responsible for the presence of homochirality in the primitive Earth is detailed.
Journal ArticleDOI
Recycling Frank: Spontaneous emergence of homochirality in noncatalytic systems
TL;DR: This work shows that the use of a Frank-like model in a recycled system composed of reversible chemical reactions, rather than the classical irreversible system, allows for the emergence of a synergetic autoinduction from simple reactions, without any autocatalytic or even catalytic reaction.
Journal ArticleDOI
Determination of Dendrigraft Poly-l-Lysine Diffusion Coefficients by Taylor Dispersion Analysis
TL;DR: Experimental results confirm that DGLs are very similar to trifunctional dendrimers (exponential growth of the molar mass, almost linear variation of the hydrodynamic radius, high branching density, and maximum of the intrinsic viscosity or of the free volume fraction for generation 4).
Journal ArticleDOI
N-Carbamoyl-α-Amino Acids Rather than Free α-Amino Acids Formation in the Primitive Hydrosphere: A Novel Proposal for the Emergence of Prebiotic Peptides
Jacques Taillades,Isabelle Beuzelin,Laurence Garrel,Vlado Tabacik,Catherine Bied,Auguste Commeyras +5 more
TL;DR: These N-protected α-amino acids offer new perspectives in prebiotics chemistry, in particular for the emergence of peptides on the prebiotic earth.
Journal ArticleDOI

TL;DR: In this paper, a molecular engine (the primary pump) is described, which works at ambient temperature and continuously generates, elongates, and complexifies sequential peptides, in a cyclic reaction sequence, whose key step is the activation of amino acids into their N-carboxyanhydrides through nitrosation by NOx.
