Antioxidant function of vitamin A.
International journal for vitamin and nutrition research. Internationale Zeitschrift fur Vitamin- und Ernahrungsforschung. Journal international de vitaminologie et de nutrition, 1978Feeding of 100 000 I.U. of Vitamin A on alternate days, five times to rats, resulted in a marked lowering in in vitro lipid peroxidation of the tissue hemogenates. alpha-Tocopherol or DPPD supplementation along with A still further reduced the in vitro lipid peroxidation of the tissues.

Oxidative Stress, Antioxidants, and Endothelial Function
Current Medicinal Chemistry, 2004Endothelial dysfunction, characterized by a loss in nitric oxide bioactivity, is an early event in the development of atherosclerosis and determines future vascular complications. Emerging evidence suggests a causal role for oxidative stress in this process. Reactive oxygen species can directly inactivate nitric oxide, modulate protein function and act

Anticancer Antioxidant Regulatory Functions of Phytochemicals
Current Medicinal Chemistry, 2011Plant foods are not only a main source of nutrients, but they are also rich in physiologically bioactive bionutrients or phytochemicals. Consumption of fruit and vegetables is associated with a decreased risk of pathological status, including cancer. Reactive oxygen species play a key role in the genesis and development of cancer.

Antioxidant Function of Thioredoxin and Glutaredoxin Systems
Antioxidants & Redox Signaling, 2000Selenium is an essential trace element with known antioxidant properties. Cytosolic thioredoxin reductase from mammalian cells is a dimeric flavin enzyme comprising a glutathione reductase-like equivalent elongated with 16 residues including the conserved carboxy-terminal sequence, Gly-Cys-SeCys-Gly, where SeCys is selenocysteine.

Modification of Muscle Protein Functionality by Antioxidants
1997Protein oxidation is an important chemical process that occurs widely in biological systems. Recent advances in protein research have led to the recognition that muscle proteins, similar to nucleic acids and lipids, can be modified by oxygen free radicals.

Antioxidant Vitamins and Their Functions in Immune Responses
1990Vitamin E, vitamin C and beta carotene (pro-vitamin A) are essential nutrients which cannot be synthesized in the human body. Each of these nutrients has its own profile of distinct functions. In addition to these unshared functions, these three micronutrients share the capacity to act as antioxidants.

Antioxidants, lipoprotein oxidation, and arterial function
Lipids, 1996AbstractLipoproteins have an important influence on arterial tissues. High levels of low density lipoproteins (LDL) may inhibit arterial function in terms of the release of nitric oxide from the endothelium. This inhibition is enhanced by the oxidation of these lipoproteins which may occur during the development of atherosclerosis.

Antioxidant Function of Thyroxinein Vivo
Endocrinology, 1968The aim of this study has been to determine whether thyroxine may have an in vivo antioxidant effect. The possibility had been suggested from in vitro work. Euthyroid, male rats were treated with a single injection of 1 mg of L-thyroxine subcutaneously 24 hr prior to sacrifice.
