Prebiotic metabolic networks?
A prebiotic origin of metabolism has been proposed as one of several scenarios for the origin of life. In their recent work, Ralser and colleagues (Keller et al, 2014) observe an enzyme-free, metabolism-like reaction network under conditions reproducing a possible prebiotic environment.
متن کاملEvolutionary attributes of simulated prebiotic metabolic networks
A metabolism-first scenario for the origin of life entails that as early as replicating entities have emerged prebiotically, they must have constituted relatively complex molecular networks, arising via spontaneous accretion of assemblies of simpler organic molecules. While it is widely accepted that selfcatalysis is a prerequisite for life, considerably less attention has been devoted to netwo...

متن کاملPrebiotic effects: metabolic and health benefits.
The different compartments of the gastrointestinal tract are inhabited by populations of micro-organisms. By far the most important predominant populations are in the colon where a true symbiosis with the host exists that is a key for well-being and health. For such a microbiota, 'normobiosis' characterises a composition of the gut 'ecosystem' in which micro-organisms with potential health bene...
متن کاملEarly Systems Biology and Prebiotic Networks
Systems Biology constitutes tools and approaches aimed at deciphering complex biological entities. It is assumed that such complexity arose gradually, beginning from a few relatively simple molecules at life’s inception, and culminating with the emergence of composite multicellular organisms billions of years later. The main point of the present paper is that very early in the evolution of life...
