then it would have larger hemoglobin. It was thought that larger mammals would need more oxygen-rich hemoglobin to support healthy function. This lab did not support this hypothesis. The results in table 1 displayed that the hemoglobin of all mammalian samples traveled about the same distance. This trend can be seen in graph 1 as the mammalian hemoglobin samples migrated the same distance. Because the proteins traveled around the same distance it means that the hemoglobin must weigh about the same

first suggestion that genes might provide the information for all proteins came from Linus Pauling’s lab at Caltech. He and his student Harvey Itano studied hemoglobin‚ the protein in red blood cells that transports oxygen from the lung to metabolically active tissues‚ like muscle‚ where it is needed. In particular‚ they focused on the hemoglobin of people with sickle-cell disease‚ also known as sickle-cell anemia‚ a genetic disorder common in Africans‚ and therefore among African Americans as well

though adult hemoglobin‚ Hb A‚ can easily release its oxygen due to the low saturation in the vein‚ normally at that level of oxygen‚ hemoglobin cannot bind oxygen to itself. In the ordinary course of things‚ fetus would not be able to bind the required oxygen for its circulation from the maternal circulation‚ but to overcome this problem fetus produces another variant of hemoglobin called Fetal hemoglobin‚ Hb F. This type of hemoglobin has a higher affinity compared to adult hemoglobin‚ that can achieve

Sickle-Cell Anemia is a genetic blood disorder caused by the presence of an abnormal form of hemoglobin. These hemoglobin molecules tend to aggregate after unloading oxygen forming long‚ rod-like structures that force the red cells to assume a sickle shape. Unlike normal red cells‚ which are usually smooth and malleable‚ the sickle red cells cannot squeeze through small blood vessels. When the sickle cells block small blood vessels‚ the organs are deprived of blood and oxygen. This leads to periodic

Thalassemia is a group of related blood disorders that cause abnormal hemoglobin production. It is a genetic disorder that is recessive; therefore both parents must be carriers to pass on the disorder in its major form. Thalassemia is categorized into two types‚ major and minor. Individuals suffering from the major form‚ tend

process is known as sickling. What is Sickle Cell Anemia? It is a blood disorder that affects hemoglobin‚ red blood cells with normal hemoglobin move easily through the bloodstream‚ delivering oxygen to all of the cells of the body. Normal red blood cells are shaped like doughnuts with the centers partially scooped out and are soft and flexible. Sickle cell anemia occurs when an abnormal form of hemoglobin is produced. HbS molecules tend to clump together‚ making red blood cells sticky‚ stiff‚ and

because of a mutation in the hemoglobin gene. Sickle cells are stiff and sticky. They tend to block blood flow in the blood vessels of the limbs and organs. Blocked blood flow can cause pain‚ serious infections‚ and organ damage. Life expectancy in people who have this disease is shortened. Anemia is a condition in which your blood has a lower than normal number of red blood cells. This condition also can occur if your red blood cells don’t contain enough hemoglobin. Red blood cells are made in

over 3 million people in the United States. It is a medical condition where the red blood cell count or the hemoglobin count is below normal and there are no enough healthy red blood cells to carry adequate oxygen to the tissues. The normal level of hemoglobin in male and females are different. In men a hemoglobin level of less than 13.5 gram/100 ml is considered as anemia and in women hemoglobin of less than 12.0 gram/100 ml is considered as anemia.

common tests we do are CBC (Complete Blood Count)‚ Hemoglobin Electrophoresis‚ and Sickle Cell Test. In CBC‚ we can count the number of red and white blood cells‚ as well as the amount of hemoglobin in the blood. We would need to draw two samples of blood. In your case‚ a sharp tool called a lancet would need to be used because your child would be young. The Hemoglobin Electrophoresis also measures the different types of oxygen-carrying hemoglobin in the blood. We would use the same technique as
