Kinetics and Mechanism of Peroxymonocarbonate Formation
Inorganic Chemistry, 2010The kinetics and mechanism of peroxymonocarbonate (HCO(4)(-)) formation in the reaction of hydrogen peroxide with bicarbonate have been investigated for the pH 6-9 range. A double pH jump method was used in which (13)C-labeled bicarbonate solutions are first acidified to produce (13)CO(2) and then brought to higher pH values by addition of base in the ...

The Mechanism of β-Hairpin Formation
Biochemistry, 2004Beta-hairpins constitute an important class of connecting protein secondary structures. Several groups have postulated that such structures form early in the folding process and serve to nucleate the formation of extended beta-sheet structures. Despite the importance of beta-hairpins in protein folding, little is known about the mechanism of formation ...

Epigenetic mechanisms in memory formation
Nature Reviews Neuroscience, 2005Discoveries concerning the molecular mechanisms of cell differentiation and development have dictated the definition of a new sub-discipline of genetics known as epigenetics. Epigenetics refers to a set of self-perpetuating, post-translational modifications of DNA and nuclear proteins that produce lasting alterations in chromatin structure as a direct ...

Mechanisms of amyloid fibril formation
Biochemistry (Moscow), 2014Amyloid and amyloid-like aggregates are elongated unbranched fibrils consisting of β-structures of separate monomers positioned perpendicular to the fibril axis and stacked strictly above each other. In their physicochemical properties, amyloid fibrils are reminiscent of synthetic polymers rather than usual proteins because they are stable to the ...

Mechanism of Formation of Elastin Crosslinks
Connective Tissue Research, 2000We examined the formation of quaternary pyridinium crosslinks of elastin formed by condensation of lysine and allysine residues using the model compounds propanal (allysine) and n-butylamine (lysine) under quasi-physiological conditions. The resulting pyridinium compounds were characterized and the structure compared with the known pyridinium ...

The mechanism of glucuronide formation
Biochemical Pharmacology, 1961Abstract The mechanism of formation of simple glucuronides in animal tissues is reviewed. So far glucuronide synthesis has been found to occur in liver and to a lesser extent in kidney of a number of animal species. Of the mammals studied cat liver slices formed very little glucuronide. More recently glucuronide formation has been discovered to occur

Engineering Headway
Central damage is the serious defect of horizontal wedge rolling products. The method of combining testing and numerical simulation is used to study the mechanism of central Damage. It represents the evolution process of the start, growth and agglomeration of the GH4169 alloy blades in the horizontal wedge rolling process, and combines the microre ...

On a mechanism of ball-lightning formation
Doklady Physics, 2002Model of strong explosion inside a cylinder is proposed for ball lightning formation. Distribution of gasdynamics parameters is given by the solution of the Sedov problem. On the ground of empirical evaluations of shock wave parameters the author supposes favorable conditions of 0.3 m diameter cluster plasma formation.
