WebMany different types of hemoglobin (Hb) exist. The most common ones are HbA, HbA2, HbE, HbF, HbS, HbC, HbH, and HbM. Healthy adults only have significant levels of HbA and HbA2. Some people may also have small amounts of HbF. This is the main type of hemoglobin in an unborn baby's body. Certain diseases are associated with high HbF … WebJan 15, 2024 · Types of Anemia. Iron-deficiency anemia: The most common type of anemia, microcytic anemia (small RBCs), develops when you lack a sufficient amount of iron in your body to make normal amounts of RBCs. Typically, iron-deficiency anemia occurs due to blood loss or decreased iron absorption. 3. Vitamin-deficiency anemia: Low levels of …

WebThe various forms of hemoglobin are named according to the types of globin chains present. Some of these hemoglobins are present in adults, while others may be found only in utero or early in infancy. ... Hemoglobin electrophoresis is often used for this purpose, because the migrational patterns of various hemoglobins are different. Assigning oxygenated hemoglobin's oxidation state is difficult because oxyhemoglobin (Hb-O2), by experimental measurement, is diamagnetic (no net unpaired electrons), yet the lowest-energy (ground-state) electron configurations in both oxygen and iron are paramagnetic (suggesting at least one unpaired electron in the complex). The lowest-energy form of oxygen, and the lowest energy forms of the relevant oxidation states of iron, are these: Hemoglobin binds and transports oxygen from the lungs to the tissues in the body. It also transports carbon dioxide from tissues back to the lungs.2 Nitric oxide and carbon monoxide can also bind with hemoglobin. Carbon monoxide binds to hemoglobin much more strongly than oxygen.
