Vitamin E is a fat-soluble vitamin whose hydrolysate is tocopherol and is one of the most important antioxidants. [1] Soluble in organic solvents such as fats and alcohols, insoluble in water, stable to heat and acids, unstable to alkalis, sensitive to oxygen, and not sensitive to heat, but the vitamin E activity is significantly reduced when fried. Tocopherol can promote the secretion of sex hormones, increase sperm motility and quantity in men, increase female estrogen concentration, increase fertility, prevent miscarriage, and can also be used to prevent and treat male infertility, burns, frostbite, capillary hemorrhage, menopausal syndrome, Beauty and so on. Recently, it has also been found that vitamin E can inhibit the lipid peroxide reaction in the lens of the eye, expand the peripheral blood vessels, improve blood circulation, and prevent the occurrence and development of myopia. The phenolic hydroxyl group of the vitamin E benzene ring is acetylated and the ester hydrolyzed to the phenolic hydroxyl group is tocopherol. People often mistakenly believe that vitamin E is tocopherol.

 

Functions

· As an antioxidant, vitamin E acts as a peroxyl radical scavenger, preventing the propagation of free radicals in tissues, by reacting with them to form a tocopheryl radical, which will then be reduced by a hydrogen donor (such as vitamin C) and thus return to its reduced state.

· As an enzymatic activity regulator, for instance, protein kinase C (PKC), which plays a role in smooth muscle growth, can be inhibited by α-tocopherol. 

· Vitamin E also has an effect on gene expression. Macrophages rich in cholesterol are found in the atherogenetic tissue. 

· Vitamin E also plays a role in neurological functions,and inhibition of platelet aggregation

· Vitamin E also protects lipids and prevents the oxidation of polyunsaturated fatty acids.
