Myoglobin: Just an Oxygen Store or Also an Oxygen Transporter?
نویسندگان
چکیده
Besides acting as an oxygen store during times of reduced blood oxygen supply, myoglobin can also facilitate intracellular oxygen transport by diffusion of oxymyoglobin along a PO(2) gradient. We reassess the importance of myoglobin-facilitated oxygen diffusion by applying new findings on the intracellular diffusivity of myoglobin in a model calculation.

Neonatal hyper- and hypothyroidism alter the myoglobin gene expression program in adulthood
Myoglobin acts as an oxygen store and a reactive oxygen species acceptor in muscles. We examined myoglobin mRNA in rat cardiac ventricle and skeletal muscles during the first 42 days of life and the impact of transient neonatal hypo- and hyperthyroidism on the myoglobin gene expression pattern. Cardiac ventricle and skeletal muscles of Wistar rats at 7-42 days of life were quickly removed, and ...
متن کاملMyoglobin and Mitochondria: How Does The “Oxygen Store” Work?
The most important condition for functioning of all living aerobic organisms is continuous supply of sufficient oxygen. The access of oxygen to metabolic processes in cells is mediated by the respiratory proteins, tetrameric blood hemoglobin (Hb) and monomeric muscle myoglobin (Mb). Myoglobin is expressed in red muscles in response to mitochondrial demand for oxygen, transporting it from sarcol...
متن کاملAerobic performance and the function of myoglobin in human skeletal muscle.
THE ROLE OF MYOGLOBIN as an oxygen storage protein in the muscles of diving birds and mammals is well-established (8). In contrast, the function of the lower myoglobin content in striated muscles of humans and other terrestrial vertebrates has long been a subject of debate. In a seminal review published in 1939, Millikan (13) identified three potential functional roles for myoglobin in the aero...
متن کاملA Computational Study of Oxygen Transport in the Body of Living Organism (RESEARCH NOTE)
Oxygen is an essential part of the living organism. It is transported from blood to the body tissue by the systematic circulation and large part of it is stored in the blood flowing in capillaries. In this work we discuss a mathematical model for oxygen transport in tissues. The governing equations are established assuming that the blood is flowing along a co-axial cylindrical capillary inside ...
