硒的特性与心血管疾病的关系

Characteristic of Selenium and Relationship with Cardiovascular Diseases

硒是生物必需的微量元素,硒的生物学特性广泛,主要是通过结合到蛋白质发挥作用,最主要的生物学功能是构成谷胱甘肽过氧化物酶,具有抗氧化性。由于硒能抑制脂质过氧化反应,消除自由基的毒害,从而保护心肌正常代谢,改善受损心脏的心肌收缩性能,维持心血管系统正常结构和功能,而且可以调节体内血脂代谢,减少或减轻动脉硬化的发生,改善血液流变学特征。

Selenium is the required trace element in biology.It has abroad biology cha racteristic.The main affection of Selenium is combined with protein.The main b iology function is composing glutathione peroxidase and has the antioxidation.S elenium can protect normal metabolize for it can control lipid peroxidation and avoid the poison of free radical.And it can maintain the normal structure and f unction of cardiovascular-system.Furthmore,it can regulate lipid and rheology of blood.
