The reducing potential of the NADH is utilized via the methemoglobinreductase pathway to maintain the iron in Hgb in its reduced form (Fe2 +).
高铁血红蛋白还原酶途径利用了NADH的还原电位维持血红蛋白中铁元素的还原态(Fe2 +)。

Excessive oxidant stress may overload the protective HMP shunt or methemoglobinreductase pathways, causing Heinz body hemolysis or methemoglobin formation, respectively.
