铁是人体内含量最多的一种必须微量元素,它广泛参与机体内的代谢过程,在细胞生命活动中起着至关重要的作用。人体内的铁主要用于血红素蛋白及非血红素蛋白的合成,包括血红蛋白、肌红蛋白、呼吸链的主要复合体、细胞色素酶和过氧化物酶等,在人体内参与氧的运输、细胞内电子传递及能量代谢等过程[1]。 Iron is one of the most essential trace elements in the human body. It is widely involved in the body’s metabolic processes and plays a crucial role in the life activities of cells. Iron in the human body is mainly used for the synthesis of heme proteins and non-heme proteins, including hemoglobin, myoglobin, major complexes of the respiratory chain, cytochrome enzymes and peroxidases, etc., and is involved in oxygen transport , Intracellular electron transfer and energy metabolism process [1].
