micronutrient metals including Cu‚ Mn‚ Mo‚ Ni‚ Se‚ and Zn are also important. Hemoglobin Hemoglobin is one of a group of heme proteins that includes myoglobin‚ cytochrome-c‚ and catalase. Hemoglobin performs the essential task of transporting dioxygen molecules from the lungs to the tissues in which it is used to oxidize glucose‚ this oxidation serving as the source of energy required for cellular metabolic processes. Hemoglobin consists of fourglobin protein subunits (depicted by different colors in

Beta Thalassemia Beta thalassemia is an inherited blood disorder characterized by the abnormal production of a blood protein called hemoglobin. This condition is caused by a mutation within the gene that is responsible for the healthy production of hemoglobin. In healthy people‚ hemoglobin carries oxygen to tissues and cells throughout the body. Patients with beta thalassemia do not have adequate levels of oxygen within the blood‚ which can cause anemia. There are two main types of beta thalassemia

Hemoglobin and its importance Oxygen is the most essential element required to sustain human life. If an adequate supply of oxygen is not circulated throughout the body to vital organs and tissues‚ brain damage‚ organ failure and death can result. Hemoglobin (Hb)‚ the iron-containing respiratory protein in red blood cells‚ is responsible for transporting oxygen from the lungs to the rest of the body. Measured in grams per deciliter (g/dL)‚ hemoglobin levels indicate the blood’s ability to carry

and less hemoglobin (HEE-muh-glow-bin) than normal. Hemoglobin is an iron-rich protein in red blood cells. It carries oxygen to all parts of the body. Hemoglobin also carries carbon dioxide (a waste gas) from the body to the lungs‚ where it’s exhaled. People who have thalassemias can have mild or severe anemia (uh-NEE-me-uh). Anemia is caused by a lower than normal number of red blood cells or not enough hemoglobin in the red blood cells. Overview Normal hemoglobin‚ also called hemoglobin A‚ has

from the abnormal production of hemoglobin S (HbS). Therefore‚ a mutation in this gene causes a lower supply of oxygen to the cells‚ which results in occlusion of the blood vessels. Individuals diagnosed with sickle-cell anemia have abnormal function of the gene that encodes for subunit B‚ which is a protein that serves as part of the hemoglobin A (HbA). The HbA is responsible for oxygen binding through the blood stream. Indeed‚ the abnormal polymerization of hemoglobin occurs in homozygous individuals

and our blood is a living tissue made up of liquid and solids. There are many diseases related to blood such as anemia which is the decrease in oxygen supply to tissue and causes hypoxia‚ thalassemia is the mutation in one or more globin gene of hemoglobin‚ etc. Therefore‚ one of blood disorders is the most common symptomatic hemoglobinopathy with the greatest prevalence in worldwide which is called sickle cell disease.

tendency to block the blood flow to the blood vessels leading to limbs and organs. Sickle Cell Anemia is caused by a mutation in the hemoglobin beta gene (HBB). This gene’s function is to give instructions for making a protein called beta-globin. Beta-globin is a subunit of hemoglobin and there are two beta-globins and two alpha-globins in hemoglobin.
