Finding the key transition states and intermediates controlling net reaction rates and selectivity [PDF]

, 2011
In this paper Campbell's degree of rate control is extended to introduce the concepts of degree of kinetic rate control, degree of kinetic selectivity control, degree of thermodynamic rate control and degree of thermodynamic selectivity control.

Electrochemistry of Redox Reaction II. On the Kinetic Equations for Chronopotentiometry [PDF]

, 1984
Basic kinetic equations of chronopotentiometric potential-time curves, in which the equations for reversible, quasi-reversible and irreversible electron transfer process appeared in special cases, were given and a chronopotentiometric method for ...

Optimization of kinetic parameters of enzymes [PDF]

Biochemistry and Molecular Biology Education, 2002
AbstractEnzymes are a product of evolution, having achieved a high specificity and catalytic performance by means of natural selection. Because catalytic mechanisms are very complex, a detailed and rigorous analysis of their optimization functions, as it has been developed in our previous work, is rather difficult for teaching purposes.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

A Theoretical Kinetic Study on Concerted Elimination Reaction Class of Peroxyl-hydroperoxyl-alkyl Radicals (•OOQOOH) in Normal-alkyl Cyclohexanes

Molecules, 2023
The concerted elimination reaction class of peroxyl-hydroperoxyl alkyl radicals (•OOQOOH) plays a crucial role in the low-temperature combustion of normal-alkyl cyclohexanes.

Interest of modelling heat transfer inside a reactor to estimate kinetic parameters [PDF]

, 2011
A space-and-time dependent model was developed for a reactor. The model, which combines heat transfer and chemical reaction, was intended to identify kinetic parameters under non-isothermal conditions for lowintermediate moisture foodstuff. In particular,

Uncertainty quantification for kinetic models in socio-economic and life sciences

, 2017
Kinetic equations play a major rule in modeling large systems of interacting particles. Recently the legacy of classical kinetic theory found novel applications in socio-economic and life sciences, where processes characterized by large groups of agents ...

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Critical Exponents for Granular Phase Transitions

, 1997
The solid--fluid phase transition of a granular material shaken horizontally is investigated numerically. We find that it is a second-order phase transition and propose two order parameters, namely the averaged kinetic energy and the averaged granular ...
