Vitamin E. Molecular graphic of vitamin E. Green spheres represent carbon atoms, white spheres represent hydrogen and red spheres represent oxygen. Solid lines represent bonds. Vitamin E is found in vegetable lipids and animal fats. It protects unsaturated fat from oxidation and is thus thought to stabilise cell membranes. It is essential for fertility and reproduction. Deficiency is rare as the dietary supply of vitamin E group chemicals is normally easy to obtain and the compounds have a long residence time in the body.
