Circadian rhythmicity by autocatalysis. [PDF]
The temperature compensated in vitro oscillation of cyanobacterial KaiC phosphorylation, the first example of a thermodynamically closed system showing circadian rhythmicity, only involves the three Kai proteins (KaiA, KaiB, and KaiC) and ATP.

Autocatalysis: At the Root of Self-Replication
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 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.

Remarks on Autocatalysis and Autopoiesis [PDF]
Abstract: The notions of collective autocatalysis and of autopoiesis are clearly related; equally clearly, they are not quite the same. The purpose of this paper is to try to clarify the relationship. Specifically I suggest that autopoiesis can be at least roughly characterized as collective autocatalysis plus spatial individuation.

Autocatalysis During Fullerene Growth
Total energy calculations with a local spin density functional have been applied to the Stone-Wales transformation in fullerene (C 60 ). In the formation of the almost exclusively observed I h isomer of C 60 with isolated ...

Structural Contributions to Autocatalysis and Asymmetric Amplification in the Soai Reaction [PDF]
Diisopropylzinc alkylation of pyrimidine aldehydes – the Soai reaction, with its astonishing attribute of amplifying asymmetric autocatalysis, occupies a unique position in organic chemistry and stands as an eminent challenge for mechanistic elucidation.

Asymmetric autocatalysis [PDF]
Several theories of asymmetric autocatalysis have been developed in the last decades. The major goal of these studies was not to elucidate the exact mechanism of asymmetric autocatalysis but to survey various autocatalytic systems for their capacity to ...

Autocatalysis as the Natural Philosophy Underlying Complexity and Biological Evolution [PDF]
The importance and different aspects of autocatalysis in evolution was analyzed. The behaviour of autocatalytic reactions mainly the Lotka-Volterra and the Schlögl equations were discussed in terms of phase change, entropy, and their oscillation ...

Shedding Light on Synthetic Autocatalysis: From Conventional Closed-Shell Chemistries to Overlooked Open-Shell Occurrences. [PDF]
Autocatalysis is a kinetic phenomenon where a reaction product catalyzes its own formation, often leading to sigmoidal reaction profiles and exponential rate acceleration.
