在冠心病的发病过程中,体内过氧负离子的大量生成是致病的重要因素。V_E在低密度脂蛋白(LDL)的核心中能防止其不饱和脂肪酸产生过氧化作用,从而使动脉粥样硬化及心肌缺血损伤得到保护作用。V_C能促进氧化型V_E转变成还原型,而后者能抑制LDL中自由基的氧化作用。一旦V_C缺乏,V_E的抗氧化作用就难以发挥。适量摄取V_E和V_C对防治冠心病和高脂血症是有益的。 In the pathogenesis of coronary heart disease, the body produces a large number of anions anion is an important factor in pathogenic. V_E protects against atherosclerosis and myocardial ischemia injury by preventing peroxidation of its unsaturated fatty acids in the core of low-density lipoproteins (LDL). V_C can promote the conversion of oxidized V_E into reduced form, while the latter can inhibit the oxidation of free radicals in LDL. Once the lack of V_C, V_E antioxidant effect is difficult to play. Moderate intake of V_E and V_C on the prevention and treatment of coronary heart disease and hyperlipidemia is beneficial.
