Methemoglobinemia - an overview ScienceDirect Topics

Methemoglobin (British: methaemoglobin) (pronounced "met-hemoglobin") is a hemoglobin in the form of metalloprotein, in which the iron in the heme group is in the Fe (ferric) state, not the Fe (ferrous) of normal hemoglobin. Sometimes, it is also referred to as ferrihemoglobin. Methemoglobin cannot bind oxygen, which means it cannot carry oxygen to tissues. It is bluish chocolate-brown in color. I… WebMethaemoglobin (MetHb) forms when the iron component in haemoglobin is oxidised from the ferrous (Fe2+) to the ferric (Fe3+) state. Methemoglobin is unable to bind oxygen and therefore cannot deliver oxygen to the tissues. Increases in methaemoglobin may occur due to genetic disorders in red blood cell metabolism or haemoglobin structure.
