Vitamin E is a biologically important molecule that, among other activities, acts as protection against the harmful effects of free radicals. Based on its structure, it can appear as tocopherol or tocotrienol. Each of them appears in four variants: α, β, γ and δ. The most active is α-tocopherol which together with ß-tocopherol is isolated from wheat germ oil. As an antioxidant, vitamin E protects biomacromolecules (e.g., polyunsaturated fatty acids) from oxidative stress and consequent damage. Neurodegenerative diseases are diseases of the central nervous system characterized by the damage and death of the nerve cells of the brain and spinal cord. Some of the neurodegenerative diseases are Alzheimer's disease, Parkinson's disease and amyotrophic lateral sclerosis. Nerve cells are also called neurons, and their role is to generate, receive and transmit nerve impulses. Thus, nerve cells have one of the most important roles by which we can communicate, move, feed, etc. By disrupting the function and markup of membranes of nerve cells, we lose all the aforementioned functions. Because vitamin E as an antioxidant protects the membrane of nerve cells, it thus helps prevent the development of neurodegenerative diseases and slows the development of symptoms in patients and ultimately the disease.
