WebA person whose body makes only sickle cell hemoglobin will suffer symptoms of sickle cell anemia. These occur because the glutamic acid-to-valine amino acid change makes the hemoglobin molecules assemble … WebMyoglobin (abbreviated Mb) is a single-chain globular protein of 153 or 154amino acids, containing a heme (iron-containing porphyrin) prosthetic group in the center around which the remaining apoprotein folds. It has eight alpha helices and a hydrophobic core. It has a molecular weight of 17,699 (with heme)daltons, and is the primary oxygen ...
Web-the secondary structure of both Hb and Mb is alpha helices-myoglobin consists of a single polypeptide chain which can bind to one molecule of oxygen and hemoglobin has four polypeptide chains which can bind to four molecules of oxygen -the oxygen bind curve of myoglobin is hyperbolic and the oxygen binding curve of hemoglobin is sigmoidal
Myoglobin belongs to the globin superfamily of proteins, and as with other globins, consists of eight alpha helices connected by loops. Myoglobin contains 153 amino acids. Myoglobin contains a porphyrin ring with an iron at its center.
