The antioxidant mechanism and free radical scavenging effect of vitamin E
Vitamin E exerts antioxidant effects, neutralizes and clears free radicals, and protects the body from oxidative damage through the following ways:

1. Directly neutralize free radicals
The molecular structure of vitamin E, such as alpha tocopherol, can bind to free radicals, such as reactive oxygen species (ROS), by providing hydrogen atoms to render them non destructive and convert them into stable substances, thereby terminating the chain reaction of free radicals.
Its lipophilic properties allow it to preferentially embed into the lipid layer of the cell membrane, directly protecting unsaturated fatty acids in the cell membrane from free radical attacks and maintaining the integrity of the cell membrane structure.
2. Interrupt the lipid peroxidation chain reaction
When free radicals attack cell membrane lipids, they trigger a chain reaction of oxidation. Vitamin E can quickly capture lipid free radicals generated during lipid peroxidation, blocking further diffusion of oxidative reactions.
3. Collaborate with other antioxidants to enhance the effect
The synergistic effect of water-soluble antioxidants such as vitamin E and vitamin C: Vitamin E clears lipid free radicals and oxidizes itself, while vitamin C can help it regenerate and restore activity, forming an antioxidant cycle.
The specific application and effect of vitamin E antioxidant
Skin protection:
Reduce UV induced free radical generation, alleviate photoaging damage, and delay the formation of wrinkles and pigmentation.
Inhibit tyrosinase activity, reduce melanin synthesis, and brighten skin tone.
Systemic antioxidant:
Reduce the risk of low-density lipoprotein (LDL) oxidation and prevent atherosclerosis.
Protect organs such as the crystalline lens and reproductive cells that are sensitive to oxidation, and reduce the risk of age-related cataracts and infertility
