甲基血红蛋白的还原是已知发生在成熟红细胞中的少数氧化还原反应之一。一个成年男子每天大约有3%的循环血红蛋白被氧化为甲基血红蛋白，因此细胞中需要一个甲基血红蛋白还原系统来维持低浓度的甲基血红蛋白（通常低于总血红蛋白的1%）。
THE reduction of methaemoglobin is one of the few oxidation-reduction reactions known to occur in the mature red blood cell. Approximately 3% of the circulating haemoglobin of an adult man is oxidized each day to methaemoglobin1and so a methaemoglobin reduction system is needed in the cell to maintain a low concentration of methaemoglobin (normally less than 1% of the total haemoglobin2).
