维生素E是一种抗氧化剂,可使体内不饱和脂质避免氧化、保持稳定。动物试验显示,高于正常剂量的维生素E可使动物免受一些化学毒物的损害,包括银、汞、铅、硒等,也包括四氯化碳、苯、甲酚等对肝脏有毒的物质。维生素E缺乏则可使动物对臭氧及二氧化氮的毒性以及对高压氧更为敏感。维生素E的吸收有赖于正常的肠粘膜。许多种吸收不良性疾病都会引起维生素E缺乏。继发性维生素E缺乏的症状多数是亚临床性的。最近在有可能发生维生素E缺乏的病人中,见到明显的临床症状群:不同程度的反射丧 Vitamin E is an antioxidant that keeps the body of unsaturated lipids from oxidation and remains stable.
