引言维生素 E 是一种脂溶性维生素,与游离原子团反应迅速。维生素 E 在细胞和细胞内膜里的存在,是防止主要磷脂的过氧化作用的首要防线。维生素 C 在细胞液中作为一种还原剂起着抗氧剂的作用。然而以前对维生素 E 和维生素 C 之间的互相作用未引起注意。最近 Packer 等人观察这两种维生素之间游离原子团的相互作用认为:这种互相作用会直接防止游离 Introduction Vitamin E is a fat-soluble vitamin that reacts rapidly with free radicals. The presence of vitamin E in cells and intracellular membranes is the primary defense against the peroxidation of the major phospholipids. Vitamin C plays a role as an antioxidant in cell fluid as a reducing agent. However, no previous attention was paid to the interaction between vitamin E and vitamin C. Recently, Packer et al. Observed the interaction of free radicals between the two vitamins and concluded that this interaction would directly prevent the dissociation
