Superoxide and singlet oxygen in milk lipid peroxidation
TLDR
In this article, the authors investigated the extent to which the excited state molecular oxygen species, singlet oxygen 1 O 2, participates in milk lipid oxidation and found that it is the immediate source of the hydroperoxides that initiate lipid oxidation catalyzed by three agents.About:

Antioxidant and free radical scavenging activity of Spondias pinnata
TL;DR: Evidence is provided that a 70% methanol extract of Spondias pinnata stem bark is a potential source of natural antioxidants and a potent iron chelator.

Antioxidant and free radical-scavenging activities of wheat germ protein hydrolysates (WGPH) prepared with alcalase
TL;DR: In this paper, the antioxidant and free radical-scavenging activities of WGPH were investigated by employing several in vitro assay systems, including the linoleic acid emulsion model system, 1,1-diphenyl-2-picrylhydrazyl (DPPH)/superoxide/hydroxyl radical scavenging, reducing power, and ferrous ion-chelating activity.

Stability of biodiesel and its blends: A review
TL;DR: A review of the use of different types of natural and synthetic antioxidants has also been presented which indicates that natural antioxidants, being very sensitive to biodiesel production techniques and the distillation processes have varying impacts on fuel stability and available literature is very much scarce.

Photogeneration of Superoxide Anion in Serum of Bovine Milk and in Model Systems Containing Riboflavin and Amino Acids
M. Korycka-Dahl,T. Richardson +1 more
TL;DR: Superoxide anion was generated in the serum of bovine milk following illumination with fluorescent light by suppression of nitro blue tetrazolium reduction by superoxide dismutase, and generation increased about 15 fold upon reduction of the ribonuclease.

Indigenous enzymes in milk: Overview and historical aspects—Part 1
Patrick F. Fox,Alan L. Kelly +1 more
TL;DR: Progress on the isolation and characterisation of these seven enzymes first isolated in the period 1925-1970, as well as ribonuclease, aldolase and glutathione peroxidase, from the milk of the cow and other species and their significance in milk and dairy products is reviewed.

Superoxide Dismutase AN ENZYMIC FUNCTION FOR ERYTHROCUPREIN (HEMOCUPREIN)
Joe M. McCord,Irwin Fridovich +1 more
TL;DR: The demonstration that O2·- can reduce ferricytochrome c and tetranitromethane, and that superoxide dismutase, by competing for the superoxide radicals, can markedly inhibit these reactions, is demonstrated.

The Reduction of Cytochrome c by Milk Xanthine Oxidase
Joe M. McCord,Irwin Fridovich +1 more
TL;DR: The data are consistent with the conclusion that xanthine oxidase generates an unstable reduced form of oxygen, presumably the superoxide anion, and that this radical is the agent which directly reduces cytochrome c and initiates the sulfite-oxygen chain reaction.

Superoxide, hydrogen peroxide, and singlet oxygen in lipid peroxidation by a xanthine oxidase system
E W Kellogg rd,I Fridovich +1 more
TL;DR: The proposal that O2- and H2O2 can directly give rise to a singlet oxygen, as follows, was supported through the use of 2,5-dimethylfuran, as an indicating scavenger of singlets oxygen.
