The Fe(II)-bleomycin complex then degrades DNA in the sample mixture via a free-radical reaction
, which can be measured photometrically.
The reaction was carried out through a free-radical reaction
mechanism involving addition of double bonds present in the butadiene oligomer, the acrylic acid, and those of the acrylamide.
The evidence is mounting, they said, that hydrogen sulfide slows ageing by inhibiting free-radical reactions
, by activating SIRT1, an enzyme believed to be a regulator of lifespan, and probably through its interactions with a gene, klotho, which appears to have its own market basket of anti-ageing activity.
These results are relevant to the investigation of neurodegenerative processes in which iron may catalyze toxic free-radical reactions
Also, the use of global models for combustion, which proceeds wholly by free-radical reactions
, the postulate of equilibrium or a pseudo stationary state for the free radicals in combustion, models for solid-catalyzed reactions that include more arbitrary constants than can be justified by the experimental data (as well-documented in a 1969 paper by Mayer and Stowe) and perfect mixing for stirred reactors are all ideas that over-simplify reality.
Melanoidins: Properties 10: Reaction H: Free-Radical Reactions
. Chapter 3.
At the time, however, there was nothing in the scientific literature linking free-radical reactions
dominate the combustion process of organic materials.
The free-radical reactions
leading to SCB and LCB and involving polymer growing radicals are in competition either with chain propagation or with chain transfer reaction to a selected added molecule.
They also found what they say appears to be a new route for nitro-PAH formulation: free-radical reactions
The non "site-specific" functionalization of ethylene-propylene-diene terpolymer (EPDM) rubber, in particular maleation, involving free-radical reactions
often leads to undesirable theological changes in the product owing to chain scission and crosslinking as well as confusion over the structure of the bound comonomer.
need metalloenzymes to progress," he says.
