Type II photooxidation mechanism of biomolecules using chloro(5,10,15,20-tetraphenylporphyrinato)indium(III) as a photosensitizer
(Soc Brasileira QuimicaSao PauloBrasil, 2008)
Lysozyme modification by the Fenton reaction and gamma radiation
(TAYLOR & FRANCIS LTD, 2002)
A comparative study was performed on lysozyme modification after exposure to Fenton reagent (Fe(E)/H2O2) or hydroxyl radicals produced by gamma radiation. The conditions were adjusted to obtain, with both systems, a 50% ...
Visible light-induced photooxidation of glucose sensitized by riboflavin
(ELSEVIER SCIENCE INC, 1999)
Ne conducted this study to evaluate the oxidation of glucose induced by visible light in the presence of sensitizers such as methylene blue and flavins (i.e., flavin mononucleotide and riboflavin). The concentration of the ...
A model to understand type I oxidations of biomolecules photosensitized by pterins
(Elsevier, 2021-09)
Photosensitized oxidations, in part responsible for the harmful effect of UV and visible radiation on biological systems, can take place through type I (generation of radicals) and type II (singlet oxygen) mechanisms. ...
OH-Initiated Photooxidations of 1-Pentene and 2-Methyl-2-propen-1-ol: Mechanism and Yields of the PrimaryCarbonyl Products
(Wiley VCH Verlag, 2014-12)
The products of the gas-phase reactions of OH radicals with 1-pentene and 2-methyl-2-propen-1-ol (221MPO) at T=298±2 K and atmospheric pressure were investigated by using a 4500 L atmospheric simulation chamber that was ...
Photooxidation of Di-tert-butyl Malonate in the Presence and Absence of Nitrogen Dioxide
(American Chemical Society, 2016-10-06)
The rate constant for the reaction of di-tert-butyl malonate (DTBM) with chlorine atoms in the gas phase was measured using cyclohexane and pentane as references. The measurements lead to a value of (1.5 ± 0.1) × 10-10 cm3 ...
Glutaredoxin GRXS13 plays a key role in protection against photooxidative stress in Arabidopsis
(OXFORD UNIV PRESS, 2012)
Glutaredoxins (GRXs) belong to the antioxidant and signalling network involved in the cellular response to oxidative stress in bacterial and eukaryotic cells. In spite of the high number of GRX genes in plant genomes, the ...
Unprecedented arsenic photo-oxidation behavior of few- and multi-layer Ti3C2Tx nano-sheets
(Elsevier, 2020)
Water contaminated by arsenic is a tremendous risk for health and environment due to its toxic and carcinogenic nature thus asking for more advanced and efficient removal strategies. Therefore, the aim of this study is to ...
Oxygen uptake in the vitamin B2-sensitized photo-oxidation of tyrosine and tryptophan in the presence of uracil: Kinetics and mechanism
(Wiley Blackwell Publishing, Inc, 2009-09)
Considering the significance of visible light-promoted reactions in complex biological media, the photo-oxidation of the amino acids (AAs) tyrosine (tyr) and tryptophan (trp) was studied in the presence of the naturally ...
