Hemoglobin is the iron-containing oxygen-transport metalloprotein in the red blood cells. It carries oxygen away from the lungs and carbon dioxide back to the lungs. A molecule of human hemoglobin (Hb) consists of 2 pairs of peptide (alpha and beta globin) chains and four heme groups, each with one atom of iron.

What is a hemoglobin simple definition?
Listen to pronunciation. (HEE-moh-GLOH-bin) A protein inside red blood cells that carries oxygen from the lungs to tissues and organs in the body and carries carbon dioxide back to the lungs.
What is considered a bad hemoglobin level?
A low hemoglobin count is generally defined as less than 13.5 grams of hemoglobin per deciliter (135 grams per liter) of blood for men and less than 12 grams per deciliter (120 grams per liter) for women. In children, the definition varies with age and sex.
What is the function of human hemoglobin?
Hemoglobin is essential for transferring oxygen in your blood from the lungs to the tissues. Myoglobin, in muscle cells, accepts, stores, transports and releases oxygen.
What are the 4 types of hemoglobin?
Four different hemoglobin species are commonly recognized: oxyhemoglobin (oxy-Hb), deoxyhemoglobin (deoxy-Hb), methemoglobin (met-Hb), and hemichromes, whose structures appear below.
What are the problems caused by Anaemia?
Left untreated, anemia can cause many health problems, such as: Extreme fatigue. Severe anemia can make you so tired that you can't complete everyday tasks. Pregnancy complications.
Does drinking water lower hemoglobin?
In this study, we found that water intake may improve anemia by increasing the hemoglobin index. In the experimental group, the increase in hemoglobin was not significant, although there were significant increases in MCH and MCHC, indicating that water assists hemoglobin synthesis.
What hemoglobin level requires a blood transfusion?
The American Society of Anesthesiologists uses hemoglobin levels of 6 g/dL as the trigger for required transfusion, although more recent data suggest decreased mortality with preanesthetic hemoglobin concentrations of greater than 8 g/dL, particularly in renal transplant patients.
What will happen if hemoglobin is absent in blood?
If Hemoglobin is absent in the blood, the blood will not appear red in color. Also when hemoglobin is absent in the blood, the blood will not be able to carry oxygen from lungs to the entire body. Hence the supply of Oxygen will be cut. It may result to death of a person.
What is the difference between hemoglobin and iron?
It's common for people to think that iron and haemoglobin are the same thing, but they're actually quite different. Iron is a component of haemoglobin and is also found in other parts of the body. It's possible to have a normal haemoglobin level but be low in iron.
Where is hemoglobin found in the body?
hemoglobin, also spelled haemoglobin, iron-containing protein in the blood of many animals—in the red blood cells (erythrocytes) of vertebrates—that transports oxygen to the tissues.
What is the most common type of hemoglobin disease?
Sickle Cell Anemia – The Most Common Hemoglobin Disease
Sickle cell anemia is one of the most frequently occurring genetic disorders that affect the red blood cells. Sickle cell anemia mostly affects people of African descent but the disease can also affect people of Hispanic, Arabic, Indian or Mediterranean descent.
Is hemoglobin A respiratory pigment?
In vertebrates the respiratory pigment is hemoglobin. Hemoglobin has a molecular weight of about 68,000 and is composed of two pairs of polypeptide chains. Each chain carries an iron-containing heme group. The hemoglobin molecule is capable of transporting four oxygen molecules.
