Detailed explanation-1: -Hemoglobin is the substance in red blood cells that carries oxygen. Oxygen from the lungs binds to hemoglobin molecules and is carried through blood vessels to the rest of the body.
Detailed explanation-2: -Hemoglobin (Hb) is the most studied of the heme containing globulin proteins and yet is not fully understood. It was one of the first proteins to be studied by X-ray crystallography, and earned Max Perutz the Nobel Prize in Chemistry in 1962.
Detailed explanation-3: -Hemoglobin comprises four subunits, each having one polypeptide chain and one heme group (Figure 1). All hemoglobins carry the same prosthetic heme group iron protoporphyrin IX associated with a polypeptide chain of 141 (alpha) and 146 (beta) amino acid residues.
