Vitamin E in Biological Systems

Abstract
Since the discovery of vitamin E over 50 years ago, its role in human health and its biological effectiveness have been under extensive research. It has been established that vitamin E deficiency states exist in humans in specific clinical situations. It is well accepted that vitamin E is the major 1ipid~soluble antioxidant in biological systems, protecting structures and functions of cell membranes from free radical damage. The impact of free radicals on the aging process and development of damage or disease and the protective role of vitamin E and other biological antioxidants in pre venting or delaying these processes is an area of active research.
