The purpose of this chapter is to examine the role of antioxidants, and thus the role of free
radicals in the activities of the immune system. The chapter is divided into three main …

Free radical generation occurs continuously within cells as a consequence of common
metabolic processes. However, in high concentrations, whether from endogenous or …

Free radicals and reactive oxygen species can damage cells and tissues of biological
organisms. Due to the fact that these compounds are generated continuously in living cells …

Vitamin 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 …

Free radicals are produced during normal cellular metabolism and consequence from the
metabolism of definite medicines or xenobiotics. Oxidative stress is a major contributing …

The immune system is extremely sensitive to oxidative damage. Many immune cells produce
reactive oxygen species as part of the body's defence against infection and depend on …

Oxidative stress, resulting from cumulative damage caused by reactive oxygen species
(ROS), is present throughout life and is thought to be a major contributor to the ageing …

Individual micronutrients have specific functions which are not shared by other
micronutrients; for instance, ascorbic acid is a cofactor in hydroxylation reactions whereas …

Free radicals have been associated with damage to cellular membranes and enzymes as
well as to the DNA in the cell nucleus. Leukocyte (white blood cell) function is dependent on …
