Electronic spectroscopy of some metal-containing free-radicals

open access: yes, 1998
Laser-induced fluorescence (LIF) spectroscopy has been used to probe the properties of some metal-containing free-radicals. These radicals were formed using three different techniques; fragmentation through electric discharge, laser ablation and laser ...

Antioxidant Protection from UV- and Light-Stress Related to Carotenoid Structures

open access: yesAntioxidants, 2019
This review summarizes studies of protection against singlet oxygen and radical damage by carotenoids. The main focus is on how substitutions of the carotenoid molecules determine high antioxidant activities such as singlet oxygen quenching and radical ...

Synthetic Strategies for 5- and 6-Membered Ring Azaheterocycles Facilitated by Iminyl Radicals

open access: yesMolecules, 2016
The totality of chemical space is so immense that only a small fraction can ever be explored. Computational searching has indicated that bioactivity is associated with a comparatively small number of ring-containing structures. Pyrrole, indole, pyridine,

Monitoring of oxidation changes of saccharides and reductones by colour indicators.

open access: yesKvasný průmysl, 2001
The article describes the colour changes of 10 indicatores by the action of radical iniciators. The majority of the indicatores has decayed on colourless products, some of them by path of colour intermediates.

Evidence of Paraoxonases 1, 2, and 3 Expression in Human Ovarian Granulosa Cells

open access: yesAntioxidants, 2021
Increasing evidence suggests that the antioxidant paraoxonase proteins, PON1, PON2, and PON3, have a role in reproduction and may be synthesized by ovarian cells.

Assay of the antioxidant capacity of foods using an iron(II)-catalysed lipid peroxidation model for greater nutritional relevance [PDF]

open access: yes, 2010
The formation of free radicals by the iron-catalysed Fenton reaction is a major cause of oxidative damage in the body. Here a common assay of antioxidant capacity, inhibition of the β-carotene-linoleic acid model of lipid peroxidation, has been modified ...

One-electron oxidation and reduction of glycosaminoglycan chloramides: a kinetic study. [PDF]

open access: yes, 2013
Hypochlorous acid and its acid-base counterpart, hypochlorite ions, produced under inflammatory conditions, may produce chloramides of glycosaminoglycans, these being significant components of the extracellular matrix (ECM).
