WebFeb 13, 2024 · The M value is an index of the discrimination between oxygen binding and carbon monoxide binding. It's actually the ratio of the partial pressures of the two gases needed to half-saturate the hemoglobin (i.e. so that 50% of iron atoms have bound O 2 or CO). M = P 1/2CO / P 1/2O 2. The lower the M value, the greater the favourability for O 2 ... WebFeb 24, 2024 · Hemoglobin is made up of two parts: a protein (globin) and a compound called heme, which comprises iron atoms and a red pigment (porphyrin). This pigment is what gives blood its red color.
