WebSep 7, 2024 · Myoglobin is a monomeric protein that has 154 amino acids residues. It consists of eight α-helicines connected through the turns with an Oxygen binding site. It has a globular structure. Myoglobin contains a heme (prosthetic) group which is responsible for its main function (carrying of oxygen molecules to muscle tissues). WebHemoglobin 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.

Dec 16, 2015 Because it is associated with cooperative oxygen binding. NONCOOPERATIVE VS. COOPERATIVE OXYGEN BINDING Noncooperative oxygen binding is commonly associated with myoglobin. It is a monomer. It has a hyperbolic oxygen binding curve and does NOT have cooperative oxygen binding. … erythr meaningLike hemoglobin, myoglobin is a cytoplasmic protein that binds oxygen on a heme group. It harbors only one globulin group, whereas hemoglobin has four. Although its heme group is identical to those in Hb, Mb has a higher affinity for oxygen than does hemoglobin.
