In guinea pigs there occurred an unexpected increase in myoglobin content in the skeletal muscle of folic acid-deficient animals compared to pair-fed controls. In this species, the change in myoglobin was associated with a typical folic acid deficiency anemia and alteration in the hematologic picture. Possible implications of this finding for the existence of important differences in the synthesis or rate of degradation of myoglobin and hemoglobin are discussed.
