Question

what is heamoglobin?

Answer 1

a red protein responsible for transporting oxygen in the blood of vertebrates. Its molecule comprises four subunits, each containing an iron atom bound to a heme group.

Answer 5

@shrutipande9 wikipedia isn't a reliable source for information...

Answer 6

oxygen-transporting substance in blood: an iron-containing protein in red blood cells that transports oxygen around the body

Answer 7

ya i agree....but it is good for the general stuff...i dont trust wikipedia if i am searching for minute details of something...

Answer 8

One of a group of globular proteins occurring widely in animals as oxygen carriers in blood. Vertebrate haemoglobin comprises two pairs of polypeptide chains, known as α-chains and β-chains (forming the globin protein), with each chain folded to provide a binding site for a haem group. Each of the four haem groups binds one oxygen molecule to form oxyhaemoglobin. Dissociation occurs in oxygen-depleted tissues: oxygen is released and haemoglobin is reformed. The haem groups also bind other inorganic molecules, including carbon monoxide (to form carboxyhaemoglobin). In vertebrates, haemoglobin is contained in the red blood cells (erythrocytes).

The red haem-containing protein in red blood cells which is responsible for the transport of oxygen and carbon dioxide in the bloodstream. Because haem contains iron, there is a deficiency of haemoglobin and impaired oxygen transport to tissues in iron deficiency anaemia.
