    Hemoglobin Lab Report

    Abstract: Hemoglobin is an iron-containing protein in red blood cells that enable the red blood cell to bind oxygen in the lung and transport the oxygen to tissues and organs throughout the body. Oxygen binds reversibly to these iron atoms and is carried throughout the blood. As part of the experiment, we computed the concentration of hemoglobin and iron in a crystalline blood sample by measuring the absorbance of the sample as methemoglobin and cynamethemoglobin at 450-650nm. Furthermore, the hemoglobin and iron concentration were also measured by means of volumetric analysis and the Wong method. The concentration of Hemoglobin and iron obtained in the experiment was in good agreement with their corresponding literature value. The computation for the error analysis suggests that the error in the concentration with respect to the absorbance contributed highly to the result, because without it, the concentration of hemoglobin and iron in the blood sample will…

    (SCD) is an inherited red blood cell disorder that is present at birth and is often more prevalent amongst African Americans.1 In order to inherit SCD, a person must inherit two abnormal hemoglobin genes, one from each parent. Hemoglobin is a protein found in red blood cells that is responsible for absorbing oxygen in the lungs and transporting it throughout the body.13 Proteins typically have four levels of structure: primary, secondary, tertiary, and quaternary. The primary structure of a…

    transported by blood through the circulatory system. It is the hemoglobin inside the red blood cells that is responsible of binding the oxygen. A hemoglobin consists of four sub units and therefore it can be termed as a tetramer. This tetramer is made of two dimers known as alpha-beta dimers. Therefore, in total hemoglobin is made up of two alpha monomers and two beta monomer. Each of these monomers makes a subunit of a hemoglobin. Each of these subunits is responsible of binding and…

    substitution of valine for glutamic acid at position 6 of the β-globin gene (Glu6Val), is the major cause of sickle cell anemia (Platt, 2008; Mtatiro et al., 2015). The mutated β-globin gene (Glu6Val) leads to the formation of sickle hemoglobin (HbS), a protein that when deoxygenated tends to polymerize into long fibers, thereby damaging the erythrocyte membrane and reducing it’s deformability (Platt, 2008; Ma et al., 2007). Since, the polymerization is directly proportional with…

    student at John Hopkins, Sherman, noticed the birefringence of deoxygenated red blood cells, recommended that low oxygen adjusted the hemoglobin structure in the molecule. In 1948 multiple individuals made discoveries. Pediatric hematologist in New York, Janet Watson, suggested the insufficiency of sickle cells in the peripheral blood of newborns was due to the fetal hemoglobin in the red blood…

    Sickle Cell Disease is a collection of inherited disorders in which the red blood cells lack hemoglobin. Hemoglobin is an essential protein to the body that assists in the color of the blood cells, as well as allowing oxygen to be carried all over the body (What is Sickle Cell Disease 2016). Sickle Cell Disease first arose in West Africa, affecting hundreds of people. The disease was thought to only affect the people of that area, but it quickly became a widespread disease. Ten to thirty percent…

    : Sickle cells pallor is a hereditary issue which causes the declaration of deficient hemoglobin coming about unpredictably formed red platelet, know as “sickle cells”. these sickle cells cause issues in the body frequently blocking blood stream and creating difficult assaults and here and there stroke. Sickle cells have distinctive organic chemistry than typical red platelets and are controlled by numerous free radical procedures. This paper will audit the infection state and examine a few…

    It could be inherited if the parents are carriers for the faulty gene (sickle cell trait) where the genes come in pairs when the child gains one faulty gene from the father and another from the mother. Causes: Sickle cell anemia results from a change in the normality of a specific hemoglobin called hemoglobin S. The change in hemoglobin S results from a mutation (point mutation) in which a single nucleotide substitution occurs. In sickle cell anemia a point mutation occurs where the glutamate…

    red blood cells in the body. (1, 19) This can cause shortness of breath, headache, fatigue and loss of energy. (1, 19) Sickle Cell Anemia is a disease in which the normal blood cells changes shape under certain conditions and becomes abnormal. It forms a sickle looking shape red blood cells. The main cause of Sickle Cell Anemia is from the mutation of a protein called Hemoglobin. (1, 7) Hemoglobin is responsible for transporting oxygen from the lungs to the various parts of the body like liver,…

    WGU Biochemistry Task 3 A1) There are several differences between the oxygenated and deoxygenated states of hemoglobin. One difference can be seen in the conformational state of the hemoglobin protein. When oxygenated, the protein takes on the T (tense) state; and when deoxygenated, the protein takes on the R (relaxed) state (Hudon-Miller, 2012b). Another difference arises when oxygen binds to the hemoglobin, resulting in a change in the shape of the protein. In the deoxygenated state, the…
