Physiological Measurement, 2007
Chemical reactions, including oxidation and reduction of molecules, occur in every cell. These reactions can lead to the production of free radicals. Free radicals react with organic substrates such as lipids, proteins, and DNA. Through oxidation free radicals cause damage to these molecules, disturbing their normal function, and may therefore ...

Lipophilized Antioxidants [PDF]
, 2019 Lipophilized antioxidants are amphiphilic molecules constituted of a lipid moiety covalently linked to a polar group possessing antioxidant properties. They are multifunctional molecules possessing interesting physicochemical (antioxidant, surface active) and biological (antimicrobial, antiviral, antiinflammatory, anticarcinogenic, etc.) properties ...

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1985
The mechanism of lipid peroxidation and the ways in which the rate of this reaction can be reduced by small quantities of certain specific chemicals, called antioxidants, are described. The types and roles of the different antioxidants found in living systems are considered.

OXIDANTS AND ANTIOXIDANTS | Antioxidants, Nonenzymatic
2006Oxidant generation is part of the normal metabolism of many types of cells. To protect itself against exposure to noxious oxidants the lung has a well-developed antioxidant system. When an imbalance occurs between oxidants and antioxidants in favor of oxidants, oxidative stress is said to occur.

Current Medicinal Chemistry, 2001
In order to ascertain the role of dietary flavonoids as antioxidants in vivo it is necessary to understand the chemical nature of the absorbed forms in the circulation in vivo and how the multiplicity of research findings in vitro reflect the bioactivity of flavonoids in vivo. Only when we gain adequate information on the circulating forms can we begin

Antioxidant properties of amidothionophosphates: Novel antioxidant molecules
Free Radical Biology and Medicine, 1996This work describes the synthesis and characterization of a new family of antioxidants. The molecules have the same active group, but different oil-to-water and octanol-to-water partition coefficients due to different substituents. Three new molecules were synthesized based on the chemical structure of the primary amide attached to a thiophosphate ...

Resistance Training, Antioxidant Status, and Antioxidant Supplementation
International Journal of Sport Nutrition and Exercise Metabolism, 2019Resistance training is known to promote the generation of reactive oxygen species. Although this can likely upregulate the natural, endogenous antioxidant defense systems, high amounts of reactive oxygen species can cause skeletal muscle damage, fatigue, and impair recovery.

Exercise, depletion of antioxidants and antioxidant manipulation
Cell Biochemistry and Function, 1998Strenuous physical activity is known to increase the production of reactive oxygen species (ROS), associated with depletion of antioxidant defence. In the present work we evaluated the level of lipid peroxidation and antioxidant components in blood of sportsmen under resting conditions and compared the data obtained with those in age- and sex-matched ...
