Hemoglobin F (Hb F, fetal hemoglobin) – makes up to 1%-2% of hemoglobin (Hb) found in adults it has two alpha (α) and two gamma (γ) protein chains.Hemoglobin A2 (Hb A2) – makes up about 2-3.5% of hemoglobin (Hb) found in adults it has two alpha (α) and two delta (δ) protein chains.Hemoglobin A (Hb A) – this is the predominant type of hemoglobin (Hb) in adults, makes up about 95%-98% of hemoglobin found in adults Hb A contains two alpha (α) protein chains and two beta (ß) protein chains.The type of globin chains present is important in hemoglobin’s ability to transport oxygen.
Different types of hemoglobin are classified according to the type of globin chains they contain. Each of the four globin chains holds a heme group containing one iron atom. Depending on their structure, the globin chains are designated as alpha (α), beta (ß), delta (δ), and gamma (γ). Another portion is made of up four protein chains called globins. One portion of hemoglobin called heme is the molecule with iron at the center (see Figure 1). The globin protein consists of chains of amino acids, the “building blocks” of proteins. Hemoglobin is made up of heme, which is the iron-containing portion, and globin chains, which are proteins. The last 2 are usually found in small amounts in blood. Under normal circumstances, adult blood contains 4 types of hemoglobin: oxygenated hemoglobin or oxyhemoglobin, hemoglobin that contains no oxygen (reduced hemoglobin) or deoxyhemoglobin, hemoglobin transporting carbon dioxide or carboxyhemoglobin, and oxidized hemoglobin or methemoglobin. Hemoglobin enables red blood cells to bind to oxygen in the lungs and carry oxygen to tissues and organs throughout your body. Hemoglobin also helps transport a small portion of carbon dioxide (CO 2), a product of cell metabolism, from tissues and organs to the lungs, where it is exhaled 1). Hemoglobin (Hb or Hgb) is the iron-containing protein found in all red blood cells (RBCs) that gives red blood cells their characteristic red color and it carries oxygen (O 2) throughout the body.
Is there a home test for hemoglobin A1c?.Is hemoglobin A1c reported the same way around the world?.Why are my hemoglobin A1c and blood glucose different?.Is there anything else I should know about the Hemoglobin A1c test?.What abnormal hemoglobin A1c results mean?.High Rates of Red Blood Cell Destruction.There are many types of anemia with specific causes and traits.Hemoglobin Abnormalities Signs and Symptoms.Can a healthy diet and nutrition help keep optimal hemoglobin levels?.Is anyone at greater risk of abnormal hemoglobin levels?.Are there warning signs for abnormally low hemoglobin levels?.Take care, fix it fast, because symptoms left too long will and can be permanent. Symptoms can be so many and seem unrelated. People used to die from severe cases and they were thought to be mentally ill. I did not know what to ask them to test for it. I went through 5 doctors before anyone would test me for B12 of course they had never had experience with such a extreme case. I had no detectable b12 and I had more symptoms than you can imagine. Every nerve in your body will degenerate and or die if you don't and you are as bad as mine was. If nothing else, get some large dose (5000) b12 sublingual tablets or liquid and take it yourself and don't stop, but you need to find a doctor that will order the test, don't worry about y our insurance, pay for it straight up if you need to. Have a doctor do a specific test for B12. I don't think they would treat a man this way if he had the same symptoms. Said I needed counseling and was depressed. I also had crazy heart beats and drs said I had no heart problems, of course the problems got way worse after they tested but they wouldn't test again.
