WitrynaABSTRACT. Methemoglobinemia is a condition in which there are high blood levels of methemoglobin. It may be congenital or acquired. The congenital form (which is rare) is the result of a defect in the methemoglobin reductase enzyme, dependent of the nicotinamide adenine dinucleotide phosphate reduced (NADPH); it is also caused by … Witrynatype II hereditary methemoglobinemia (deficient in NADH cyto-chrome b 5 reductase) showed virtually no activity for hydrox-ylamine reduction, compared with normal fibroblasts. These results indicate a novel direct role for NADH cytochrome b 5 reductase and cytochrome b 5 in xenobiotic metabolism and
WitrynaNormally, through the NADH or NADPH dependent methemoglobin reductase enzymes, methemoglobin is reduced back to hemoglobin. Methylene blue is employed as a medication for the treatment of methemoglobinemia, which can arise from ingestion of certain pharmaceuticals, toxins, or broad beans. 4.5 Methylene blue … Witryna(26) Schwartz JM et al.

J Biol Chem. 1988 Jun 5;263(16):7539-43.PMID: 3131323 WitrynaMethemoglobin is a form of the oxygen-carrying protein hemoglobin, in which the iron in the heme group is in the ferric Fe 3+ state, not the ferrous Fe 2+ of normal hemoglobin. The ferric iron in methemoglobin does not bind oxygen; therefore erythrocytes containing methemoglobin are unable to carry oxygen to tissue. 8 The NADH …
