DPPH and oxygen free radicals as pro-oxidant of biomolecules
(PERGAMON-ELSEVIER SCIENCE LTD, 2008-03)
Numerous investigations exist about the alterations that oxygen free radicals can provoke on biomolecules; these modifications can be
prevented and/or reversed by different antioxidants agents. On the other hand, ...
Organic radicals for the enhancement of oxygen reduction reaction in Li-O2 batteries
(Royal Society of Chemistry, 2015-10)
We examine for the first time the ability of inert carbon free-radicals as soluble redox mediators to catalyze and enhance the oxygen reduction reaction in a (TEGDME)-based electrolyte. We demonstrate that the tris(2,4,6 ...
Singlet oxygen quenching and radical scavenging capacities of structurally-related flavonoids present in Zuccagnia punctata Cav.

Singlet oxygen quenching and radical scavenging capacities of structurally-related flavonoids present in Zuccagnia punctata Cav
(Taylor & Francis Ltd, 2009-01-01)
The singlet oxygen ((1)O(2)) quenching and free radical (DPPH(center dot), ABTS(center dot+) and O(2)(center dot-)) scavenging ability of three structurally-related flavonoids (7-hydroxyflavanone HF, 2',4'-dihydroxychalcone ...
Profile of Maytenus aquifolium action over free radicals and reactive oxygen species
(2007-07-01)
Reactive oxygen species (ROS) and free radical species have been implicated in initiating, accompanying or causing many diseases in living organisms; there is thus, a continual need for antioxidants molecules to inactivate ...

Nitric Oxide: Oxygen Radical Interactions in Atherosclerosis
(Sociedad de Biología de Chile, 2000)
A computational investigation of the reactions of tyrosyl, tryptophanyl, and cysteinyl radicals with nitric oxide and molecular oxygen
(Taylor & Francis Ltd, 2019-01)
Proteins are main targets of oxidants in biological systems. This oxidation may occur in the protein backbone as well as in certain amino acid side chains, depending on the oxidant and amino acid intrinsic reactivity. ...
