Vitamin C, vitamin E and β-carotene difference
 Vitamin C, vitamin E and β-carotene has inhibitory activity of free radicals, protecting body cells, but their effects are different:
 Vitamin C is water-soluble vitamins, in cells within the blood and fluid in the circulation

 Vitamin E is fat soluble and can protect unsaturated fatty acids the body from free radicals damage, but not saturated fatty acids have a protective function of internal organs

 β-carotene are regulated by hypoxia parts, such as muscle in the tiny blood vessels, so for the eye, lung microvascular more parts of the most protective effect. Each play the best effect of antioxidants in different parts, three with the added, in order to achieve comprehensive protection role of the body.

Vitamin E-metabolic absorption
 Vitamin E acid, pancreatic juice and the presence of fat, under the action of lipase to the mixed particles in the upper small intestine by passive diffusion of non-saturated mode is absorbed by intestinal epithelial cells. Various forms of vitamin E is absorbed mostly carried by the chylomicrons reach the liver through the lymphatic system. Vitamin E in the liver by chylomicrons and very low density lipoprotein (VLDL) into the carrier plasma effect. Chylomicrons in the blood circulation of the decomposition process, the absorption of vitamin E transfer into lipoprotein cycle, and other debris as chylomicrons. α-tocopherol is the main oxidation product quinone α-birth, the aldehyde hydrogen generated in the off glucuronic acid. Glucuronic acid excretion through the bile or further degraded in the kidneys was produced from α-fertility acid excretion of uric acid.
