Autocatalysis: At the Root of Self-Replication

Artificial Life, 2011
Autocatalysis is a fundamental concept, used in a wide range of domains. From its most general definition, that is, a process in which a chemical compound is able to catalyze its own formation, several different systems can be described. We detail the different categories of autocatalyses, and compare them on the basis of their mechanistic, kinetic ...

Empirical Description of Chiral Autocatalysis

The Journal of Physical Chemistry A, 2006
The only known example of chiral autocatalysis is the alkylation of N-heterocyclic aldehydes with iPr(2)Zn (Soai reaction). The mechanism and some details of this reaction are not yet clear. An empirical formula is proposed here for the description of this chiral autocatalytic reaction.

On a mechanism for autocatalysis

Chemical Engineering Science, 1972
Abstract The mechanism proposed by Walles and Platt for an autocatalytic reaction A → B + C is analysed by the method of singular perturbations. This has some features of interest in that the stable root of the degenerate problem changes during the course of the reaction and an intermediate solution with a different dependence on the small ...

Asymmetric Autocatalysis: Facts and Fancy

Journal of Macromolecular Science: Part A - Chemistry, 1989
Apparently no definitive experiments have ever been reported which could be defined as asymmetric autocatalysis. This paper discusses the design of several experiments which might lead to asymmetric autocatalytic reactions.

Autocatalysis in a biological system

Journal of Theoretical Biology, 1971
Abstract A biochemical scheme is analyzed in which the synthesis of a precursor is catalyzed by its product. The scheme shows hysteresis in the steady state concentrations of the intermediates only if the outflow from the system is by reaction with a reversible enzyme. The construction of open systems to correspond to an in vivo environment and the

Autocatalysis, information and coding

Biosystems, 2001
Autocatalytic self-construction in macromolecular systems requires the existence of a reflexive relationship between structural components and the functional operations they perform to synthesise themselves. The possibility of reflexivity depends on formal, semiotic features of the catalytic structure-function relationship, that is, the embedding of ...

Water and Autocatalysis in Living Matter

Electromagnetic Biology and Medicine, 2009
Water plays a fundamental role in living organisms. Liquid water includes coherence domains (CD) where all molecules oscillate in unison in tune with a self-trapped electromagnetic field at a well-defined frequency. The coherent oscillations produce an ensemble of quasi-free electrons, able to collect noise energy from the environment and transform it ...
