Myohemoglobin | definition of myohemoglobin by ... - Medical …
Myoglobin acts as a temporary oxygen store from which oxygen is drawn as the muscle requires it. a relatively small globular protein (MW = 17 000) consisting of 153 amino acids in a POLYPEPTIDE CHAIN and one HAEM group.
Myoglobin - Wikipedia
Myoglobin (symbol Mb or MB) is an iron - and oxygen -binding protein found in the cardiac and skeletal muscle tissue of vertebrates in general and in almost all mammals. [5][6][7][8][9] Myoglobin is distantly related to hemoglobin.

2024年12月7日 · (my-oh-hee-moh-gloh-bin)an iron-containing protein, resembling haemoglobin, found in muscle cells. Like haemoglobin it contains a haem group, which binds reversibly with oxygen, and so acts as an oxygen reservoir within the muscle fibres.
Chapter 6: Hemoglobin and Myoglobin - McGraw Hill Medical
Hemoglobin is a heterotetrameric oxygen transport protein found in red blood cells (erythrocytes), whereas myoglobin is a monomeric protein found mainly in muscle tissue where it serves as an intracellular storage site for oxygen.
Myoglobin - an overview | ScienceDirect Topics
Myoglobin is a water-soluble protein composed of a single polypeptide chain, globin, containing eight α-helices. It is connected to a prosthetic heme group, an ion (II) protoporphyrin–IX complex (Pegg and Shahidi, 1997). The latter consists of four pyrrole groups containing a centrally located atom of iron (Figure 3.23).
Myoglobin: an essential hemoprotein in striated muscle
Myoglobin is a cytoplasmic hemoprotein, expressed solely in cardiac myocytes and oxidative skeletal muscle fibers, that reversibly binds O2 by its heme residue, a porphyrin ring:iron ion complex. Since the initial discovery of its structure over 40 …

2022年5月2日 · Myohemoglobin (myoglobin) is a harmful product of rhabdomyolysis, which is a clinical syndrome secondary to skeletal muscle injury . Rapid release of myohemoglobin is the main cause of renal failure, and the pathophysiology is as follows: renal vasoconstriction with resultant ischemia, tubular obstruction due to myohemoglobin cast formation ...
Molecule of the Month: Myoglobin - RCSB: PDB-101
Myoglobin is a small, bright red protein. It is very common in muscle cells and gives meat much of its red color. Its job is to store oxygen, for use when muscles are hard at work. To do this, it uses a special chemical tool to capture slippery oxygen molecules: a heme group.
Myoglobin: What It Is, Function, Test & Results - Cleveland Clinic
2021年11月24日 · Myoglobin is a protein that’s found in your striated muscles, which includes skeletal muscles (the muscles attached to your bones and tendons) and heart muscles. Its main function is to supply oxygen to the cells in your muscles (myocytes). All cells in your body need oxygen in order to function. They use oxygen to convert stored energy.
