Vitamin E(vitaminE) is a fat-soluble vitamin, which is the general name of tocopherol (T) and tocotrienols (T-3). It is an important component of cell membrane and the main antioxidant on cell membrane. Vitamin E is widely found in animal and plant foods, and animal foods are mainly da-type, and vegetable oils contain more vitamin E, which is parallel to polyene fatty acids such as linoleic acid. Vitamin E is an antioxidant of polyene fatty acids, which combines with polyvalent unsaturated fatty acids (PUFA) of phospholipid on the cell membrane to form a complex, which stabilizes the membrane structure and prevents PUFA on the biofilm and sulfur-containing enzymes in cells from being destroyed by oxidants. When vitamin E is deficient, PUFA on erythrocyte membrane is prone to peroxidation, which damages erythrocyte membrane and leads to hemolysis.
