Chemistry – A European Journal, Accepted Article.Short amyloidogenic oligopeptides (APRs) are proposed as early macromolecules capable of forming solvent‐separated nanosystems under prebiotic conditions. This study provides experimental evidence that APRs, such as the aggregation‐prone oligopeptide A (APR‐A), can undergo mutational transitions to form distinct variants, and convert to APR‐B, either ...

Macromolecular Chemistry and Physics, Volume 223, Issue 23, December 2022., 2022 Polyesters synthesized prebiotically through dehydration synthesis of α‐hydroxy acids can assembly into membraneless microdroplets proposed to be primitive compartment models. Here, in order to more widely probe the conditions amenable to such primitive polyester microdroplet formation, the effects of synthesis temperature and monomer chirality on ...

Animal, 2011 Prebiotics are suggested as an alternative to antibiotics in animal rearing. Fermentable substances such as inulin or lactulose have been proposed to stimulate the immune system and health by modulation of the intestinal flora and its fermentation ...

Journal of Functional Foods, 2020 Prebiotics play a widely recognized role in the regulation of intestinal microbiota, but most related studies have not been explored beyond the genus level. In recent years, some newly publicized findings have opened a window of opportunity regarding the

Electron spin and the origin of Bio-homochirality II. Prebiotic inorganic-organic reaction model [PDF]
arXiv, 2014 The emergence of biomolecular homochirality is a critically important question about life phenomenon and the origins of life. In a previous paper (arXiv:1309.1229), I tentatively put forward a new hypothesis that the emergence of a single chiral form of biomolecules in living organisms is specifically determined by the electron spin state during their ...

Molecular Imprinting: The missing piece in the puzzle of abiogenesis? [PDF]
arXiv, 2018 In a neglected 2005 paper, Nobel Laureate Paul Lauterbur proposed that molecular imprinting in amorphous materials -- a phenomenon with an extensive experimental literature -- played a key role in abiogenesis. The present paper builds on Lauterbur's idea to propose imprint-mediated templating (IMT), a mechanism for prebiotic peptide replication that ...

Thermodynamics of prebiotic synthesis [PDF]
arXivIn this paper, I outline the correspondence of vector partitions with the combinatorics of dynamical systems whose states are partitions of multisets. I use the notion of a limiting shape of vector partitions to determine properties of the equilibrium distribution for these systems.
