维生素现已知道至少有8种具有V_E活性生育酚。以α——生育酚的活性最强。具有许多不同的但又是相关的作用。它是细胞内外的抗氧化剂,阻止细胞内不饱和脂肪酸的氧化。如果缺乏足够V_E时,不饱和脂肪酸能被氧化,生成脂质氢过氧化物,直接损害细胞组织。细胞活性越强,作为提供能量的脂质进入细胞就越多。V_E的抗氧化性质还能保持红细胞的稳定性和维持毛细血管的完整性。V_E还具有对垂体——中脑系统具有调节作用,促进产生激素来刺激甲状腺和肾上腺素的分泌V_E。缺乏症的发生部位和特征取决
Vitamins It is now known that there are at least 8 kinds of tocopherols with V_E activity. To α - tocopherol activity of the strongest. There are many different but related functions. It is an antioxidant inside and outside the cell, preventing the oxidation of unsaturated fatty acids inside the cell. In the absence of enough V_E, unsaturated fatty acids can be oxidized, generating lipid hydroperoxides, which directly damage the tissues of the cells. The stronger the cellular activity, the more the lipid as the energy supply enters the cell. V_E antioxidant properties can also maintain the stability of red blood cells and maintain capillary integrity. V_E also has the regulation of the pituitary-mesial system, and promote the production of hormones to stimulate thyroid and epinephrine secretion V_E. The location and characteristics of the deficiency depend on it
