TL;DR: Particle-induced formation of AA metabolites and ROS was dependent on mitogen-activated protein kinase kinase 1 activation of cytosolic phospholipase A2 (cPLA2) as shown by inhibitor studies, whereas LTB4 production and 8-isoprostane were strongly dependent on particles' oxidative potential.

Radical-assisted melanoidin formation during thermal processing of foods as well as under physiological conditions.
TL;DR: EPR spectroscopy of orange-brown melanoidins revealed the protein-bound 1,4-bis(5-amino-5-carboxy-1-pentyl)pyrazinium radical cation (CROSSPY) as a previously unknown type of cross-linking amino acid leading to protein dimerization.

Antioxidant mechanisms of polyphenolic caffeic acid oligomers, constituents of Salvia officinalis.
TL;DR: In this article, the antioxidant potential of Salvia officinalis constituents was investigated with regard to their radical scavenging activity and the stability and structure of the intermediate radicals, including O4- and O3-semiquinones.
Chemical studies of proanthocyanidins and hydrolyzable tannins.
TL;DR: Using NMR spectroscopy, this work could confirm phenolic coupling reactions of epigallocatechin gallate and pentagalloyl glucose after radical-induced oxidation and determine scavenging rate constants with hydroxyl radicals and decay rates of the respective aroxyl radical rates.

Marchantins and related polyphenols from liverwort: Physico-chemical studies of their radical-scavenging properties
TL;DR: One compound, Perrottetin D, furthermore gave proof to the hitherto only kinetically verifyable superior radical-scavenging capability of the aroxyl radical derived from a phenolic antioxidant.
