alpha-tocopherol

Alpha-tocopherol is the most biologically active form of vitamin E, a fat-soluble antioxidant essential for maintaining the integrity of cell membranes. It functions primarily by scavenging lipid peroxyl radicals, thereby terminating lipid peroxidation chain reactions. Beyond its antioxidant capacity, alpha-tocopherol modulates cell signaling pathways and gene expression, influencing processes such as inflammation and immune function. It is used clinically to treat vitamin E deficiency states, often associated with malabsorption syndromes like cystic fibrosis or genetic disorders like abetalipoproteinemia and ataxia with isolated vitamin E deficiency (AVED). It has also been extensively studied for its potential neuroprotective effects in Alzheimer's disease and its role in cardiovascular and cancer prevention.
