Myoglobin

Synonym(s)

  • myohemoglobin

Definition(s)

A red iron-containing protein pigment in muscles that is similar to hemoglobin but differs in the globin portion of its molecule, in the smaller size of its molecule (as in the mammalian heart muscle which has only one fourth the molecular weight of the hemoglobin in the blood of the same animal), in its greater tendency to combine with oxygen, and in its absorption of light at longer wavelengths. Called also myohemoglobin.
