Mesencymal Marker. Myoglobin is an oxygen-binding protein present only in striated muscles (skeletal and cardiac). It serves as another marker of muscle differentiation, occurring later in myogenesis than actin. It is a marker of muscle differentiation with lower sensitivity, but higher specificity than desmin.
Chemical stored in muscle that contains iron and oxygen.
a protein which is present within muscle cells. It is made of a single molecule of haem and a single globin polypeptide.
the oxygen-carrying pigment in muscle.
purple-red colouring matter of muscle (2% of total muscle protein)
The form of hemoglobin found in muscle cells.
the oxygen carrying/storing protein found in the muscles.
The oxygen-transporting pigment of muscle tissue.
A haemoprotein that reversibly binds dioxygen and stores it in muscle tissue.
A red iron-containing protein pigment in muscles that is similar to hemoglobin.
An oxygen-binding pigment that is especially common in slow skeletal muscle fibers and cardiac muscle cells.
a hemoprotein that receives oxygen from hemoglobin and stores it in the tissues until needed
Myoglobin is a globular protein occurring widely in muscle tissue as an oxygen carrier. It supplies oxygen to the muscle during strenuous exercise, when the muscle oxygen demands out paces the supply from the blood.
A ferrous proto-porphyrin globin complex, present in cytoplasm. Myoglobin contributes to the color of muscle and acts as a store of oxygen.
A protein in the muscle that binds oxygen in the cells. Meat color is directly impacted by this protein. For example, myoglobin plus oxygen (from air) creates oxymyoglobin, which is responsible for the bright cherry-red color in fresh meat.
Iron-containing protein found in muscle cells, related to hemoglobin in structure and function.
The oxygen-transporting protein of muscle, resembling blood hemoglobin in function.
( my-uh-glow-bin) [Gk. mys, muscle + L. globus, a ball] An oxygen-storing, pigmented protein in muscle cells.
Protein that holds and stores oxygen within the muscles and tissues.
An oxygen-transporting muscle protein.
An oxygen-carrying muscle protein that makes oxygen available to the muscles for contraction.
Oxygen-carrying protein similar to haemoglobin, found in muscle.
Myoglobin is a single-chain globular protein of 153 amino acids, containing a heme (iron-containing porphyrin) prosthetic group in the center around which the remaining apoprotein folds. With a molecular weight of 16,700 daltons, it is the primary oxygen-carrying pigment of muscle tissues. Unlike the blood-borne hemoglobin, to which it is structurally related, this protein does not exhibit cooperative binding of oxygen, since positive cooperativity is a property reserved for multimeric proteins.
