Gibson's methemoglobinemia

Methemoglobinosis (from the Greek “supraglobin heme blood”) is a disease caused by a violation of redox reactions, as a result of which the hemoglobin molecule changes its optical density. There is a transition in the amount of reduced hemoglobin over time. As soon as hemoglobin proteins are reduced with protein compounds or hydrogen atoms, respiratory processes stop. In this case, protein destruction occurs and accumulation
