Hemoglobin

body produces abnormal hemoglobin (hemoglobin S) which is found in red blood cells. The abnormally shaped red blood cells are shaped in a crescent like form, this makes them sticky and rigid and prone to getting trapped in small vessels, which blocks blood flow to important parts of the body, this is how Sickle cell got its name. Sickle cell anemia occurs when a person inherits two abnormal copies of the hemoglobin gene, which is found in chromosome 11 in both parents. Hemoglobin or Haemoglobin is the

Sickle Cell Anemia or Sickle Cell Disease is an inherited blood ailment. Those suffering from Sickle Cell Disease have abnormal S/ sickle hemoglobin in the red blood cells. Hemoglobin is the protein in the blood that aids in carrying oxygen throughout the body. The ailment takes its appellation from the shape of the red blood cells of a person affected by Sickle Cell Disease, which have the shape of a sickle. They are stiff and adhesive rather than a disk like normal cells. The misshapen cells tend

Hemoglobin has a relatively low attraction for oxygen, but once a heme group can bind with one molecule of oxygen; a structural change occurs creating a more oxygenated form that can attract more oxygen molecules. This results in a chain reaction that causes easier binding between the second, third and fourth molecules of oxygen to the heme group. Oxy-hemoglobin has an oxygen affinity that is many times greater than that of deoxy-hemoglobin. As oxygen binding is said to be reversible, both oxy-hemoglobin

cell disease.As to this day there is really no cure for sickle cell disease.Red blood cells take oxygen from the air we breathe into our lungs to all parts of the body. Oxygen is carried in red blood cells by a substance called hemoglobin(Hemoglobin –

transported to the red blood cells. This means that oxygen is not being transported to the hemoglobin protein. The hemoglobin protein has to be released from the red blood cells and be released into the plasma by enzymes that contain heme. After the enzyme release the protein, the red blood is destroyed and hemoglobin can release oxygen into the bloodstream. With Alpha Thalassemia, the low functioning numbers of hemoglobin are not enough to provide stable oxygen levels. If the levels are too low anemia is

The Genetics Home Reference writes that sickle cell disease affects the body’s blood, in particular the red blood cells. The hemoglobin in an afflicted person is abnormal and can warp the shape of the red blood cells into a the shape of a sickle. Results of the odd-shaped red blood cells is them getting caught in blood vessels or breaking down too early, often causing anemia (an insubstantial amount of red blood cells) to occur. Because of these blockages, tissues and organs can be deprived of their

Sickle-cell disease majorly affects the hemoglobin that is present in our blood. The job of hemoglobin is to help transport oxygen and carbon dioxide to and from the cells throughout our body. Hemoglobin is present specifically in our red blood cells. Each red blood cell contains two hundred and eighty million hemoglobin molecules. Red blood cells normal shape is a biconcave shape because of the lack of many organelles and a nucleus. The shape is so important to a red blood cells functioning that

Sickle cell anemia (SCA), also known as HbSS disease, is a common life-threatening inherited blood disorder in the world. It is widespread in Africa, Italy, Greece, Turkey, India, and Saudi Arabia. Sickle cell disease was reported In Saudi Arabia for the first time in the 1960s. Although the rate of patients who suffer from sickle cell disease in Saudi Arabia is not clear, it varies according to the different provinces. The highest rate of patients is in the Eastern and southwestern provinces. This

Introduction The term of Sickle cell disease (SCD) describes a group of inherited red blood cell disorders. “Inherited” means that it is passed by genes from parents to their children. People who have SCD have abnormal hemoglobin in their red blood cells, called hemoglobin S. This abnormality leads to a propensity for the cells to assume an rigid sickle-cell shape. Sickle cell disease is associated with a number of acute and chronic health problems as severe infections, severe pain, stroke and an
