    • 2 Pages

    Hemoglobin functions as transporter of oxygen molecular. The hemoglobin picks up O2 from the pulmonary system and delevers it to the body cells. oxyhemoglobin is a hemoglobin louded with O2 and deoxyhemoglobin is not louded with O2 . Blood in arteries is brighter red than the blood in veins. Hemoglobin molecule has four units of globin in addition to four units of heme. Estimation of serum Hb is a test that measures the level of free Hb in the liquid part of the blood (the serum). This test is done

    noncovalently bound to myoglobin and is essential for the biological activity of the protein. A three-dimensional structure of hemoglobin is determined by X-ray crystallography showed hemoglobin is made up of four polypeptide chains, each of those chains has a very similar three-dimensional structure to the single polypeptide chain in myoglobin. The major type of hemoglobin found in adults (HbA) is made up of two different polypeptide chains: the alpha-chain that consists of 141 amino acids residues

    in Hemoglobin's Structure Can Disturb Hemoglobin Function Abstract: The fact that a molecule?s structure determines its function can be seen through the oxygen transporter protein, hemoglobin. Hemoglobin can take two forms, oxy state and deoxy state, and each performs a distinct function for the hemoglobin. In a normal hemoglobin, the oxygen binds to a heme group during the oxy state and releases oxygen during the deoxy state. However, when hemoglobin is mutated like in sickle cell anemia

    transports oxygen and carbon dioxide to and from the cells by the help of hemoglobin - red protein molecule that comprise of four subunits, each containing an iron atom bound to a heme group - where it has the role of transporting oxygen and carbon dioxide to and from the cells. Oxygen get transported through the bloodstream by hemoglobin, it binds to the smaller protein structures of hemoglobin to move throughout the bloodstream. Hemoglobin carries around 98% while traveling through the bloodstream. In contrast

    Sickle cell anemia is a blood disorder that is inherited from both parents in which the body produces abnormally shaped red blood cells. In sickle cell anemia, the hemoglobin in red blood cells links together; resulting in the red blood cells to become rigid and a C-shaped. These deformed cells block blood and oxygen flow in blood vessels. Sickle cells deteriorate quicker than normal red blood cells, which results in anemia. Sickle cell anemia is a genetic disorder. For a person to have sickle cell

    disease is caused by a mutation in the hemoglobin gene. In healthy condition, normal RBCs are circular and flexible. The hemoglobin molecules inside the cells are free moving, which help them to maintain their shape and flexibility. Due to their flexible shapes, RBCs are able to move through the blood vessels without any hindrance. In case of a certain mutation in the hemoglobin gene, abnormal hemoglobins called ‘Hemoglobin S.’ are produced. The mutated hemoglobin molecules form chemical bonds with each-other

    Hemoglobin is a metalloprotein that conveys oxygen [1] from lungs to the peripheral tissues such as muscles, liver and intestines. Human adult hemoglobin (Hb) is a tetrameric blood protein, consisting of two pairs of  and β polypeptide chains. The hemoglobin tetramer contains a total of 6 Tryptophanes. The intrinsic fluorescence of Hb originates mainly from a Trp residue located near to the heme moiety. Methotrexate, a well-known inhibitor of dihydrofolate reductase [2] an enzyme which inhibits

    move and squeeze through your blood vessels more efficiently. Also, the red blood cell contains a protein rich in iron called hemoglobin A, which carries oxygen from the lungs to the rest of the body. Hemoglobin S is the abnormal hemoglobin found in sickle cells and is what makes the sickle cell take its crescent shape. Normal hemoglobin looks like little dots, where hemoglobin S forms stiff strands which makes it into its shape. The sickle or crescent shape is harmful because it will get lodged in

    such as anemia which is a decrease in the amount of oxygen carrying substance found in red blood cells, infection, and many other disorders. A complete blood count test usually includes platelet count, white blood cell count, red blood cell count, hemoglobin, red blood cell indices, mean platelet volume and white blood cell types. White blood cell count is an increase in fighting cells circulating in your blood. White blood cell count is also called leukocytosis. There are five major types of white
