Question

Oxidation state of iron in oxygenated myoglobin

Answer 1

Answer:

Myoglobin mainly functions as an oxygen-storage protein in muscle. When the iron achieves an oxidation state of +2(ferrous state), Fe can bind to an oxygen molecule and forms an oxymyoglobin. Prior to the oxygen binding to iron, iron is located 0.55A above the planar porphyrin ring.
