The Antioxidants and Pro-Antioxidants Network: An Overview

Current Pharmaceutical Design, 2004
Living beings have evolved over the past two billion years through adaptation, to an increasing atmospheric oxygen concentration, by both taking advantage of oxygen activating function and developing a complex control network. In these regards, potentially damaging species (reactive oxygen, nitrogen and chlorine species) arise as by-products of ...

The Antioxidant Debate

EXPLORE, 2009
Abstract Patients with cancer are taking antioxidant supplements in combination with conventional chemotherapy and radiotherapy to enhance the anticancer activity and to reduce the side effects of conventional treatment. Many oncologists are concerned that the protective mechanisms of antioxidants may not distinguish between normal and ...

Creatine as an antioxidant

Amino Acids, 2011
Creatine monohydrate (Cr), the most diffuse supplement in the sports industry, is receiving greater attention because of its beneficial effects in a wide number of human degenerative diseases and conditions. These effects can be barely explained on the basis of the sole ergogenic role of the Cr/CrP system.

Antioxidants in food and food antioxidants

Nahrung/Food, 2000
Antioxidants may be present in foods as endogenous factors or may be added to preserve their lipid components from quality deterioration. Synthetic antioxidants such as butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), propyl gallate (PG) and tert-butylhydroquinone (TBHQ) are commonly used in food formulations.

OXIDANTS AND ANTIOXIDANTS | Antioxidants, Nonenzymatic

2006
Oxidant 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.

Exercise, depletion of antioxidants and antioxidant manipulation

Cell Biochemistry and Function, 1998
Strenuous 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 ...

A Review On Free Radicals and Antioxidants.

Infectious Diseases - Drug Targets, 2020
Free radicals are generated in our body by several systems. A balance among free radicals and antioxidants is an important matter for appropriate physiological function. If free radicals become greater than the ability of the body to control them, a case

Antioxidants and cataract

Free Radical Research, 2013
The major causes for cataract formation are free radicals, and these free radicals are neutralized by the presence of endogenous antioxidants in the eye. Using xenobiotics, it has been confirmed that free radicals mediate the formation of cataract.
