Myoglobin - 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 Properties of myoglobin 153 AA Bigger than hemoglobin Compact molecule 70% of main chain is folded into 8 alpha helices Tertiary structure Inside consists of almost entirely non-polar residues Single subunit Hemoglobin - found in blood, in RBS or Erythrocytes. The iron-protein component in the red  blood cells that carries oxygen to the tissues Hb has less affinity for oxygen than Mb Structure of Heme Group -  A heme is a prosthetic group for various proteins including globins  and cytochromes.
