Vitamin E is a group of eight fat-soluble compounds that include four tocopherols and four tocotrienols. Vitamin E deficiency can cause nerve problems. Vitamin E helps protect cell membranes from reactive oxygen species.
As a radical scavenger, Vitamin E delivers a hydrogen (H) atom to free radicals. At 323 kJ/mol, the O-H bond in tocopherols is about 10% weaker than in most other phenols. This weak bond allows the vitamin to donate a hydrogen atom to the peroxyl radicals and other free radicals, minimizing their damaging effect. The thus-generated tocopheryl radical is recycled to tocopherol by a redox reaction with a hydrogen donor. As it is fat-soluble, vitamin E is incorporated into cell membranes, which are therefore protected from oxidative damage.
