The name hemoglobin is the concatenation of heme and globin, reflecting the fact that each subunit of hemoglobin is a globular protein with an embedded heme (or haem) group; each heme group contains an iron atom, and this is responsible for the binding of oxygen. The most common type of hemoglobin in mammals contains four such subunits, each with one heme group.

A heme group consists of an iron (Fe) atom held in a heterocyclic ring, known as a porphyrin. The iron atom, which is the site of oxygen binding, bonds with the four nitrogens in the center of the ring, which all lie in one plane. The iron is also bound strongly to the globular protein via the imidazole ring of a histidine residue below the porphyrin ring. A sixth position can reversibly bind oxygen, completing the octahedral group of six ligands. Oxygen binds in an "end-on bent" geometry where one oxygen atom binds Fe and the other protrudes at an angle.

Haemoglobins are more commonly known as red blood cells. Iron not only gives them their red colour, it is used in the process of carrying oxygen. Oxygen transportation is the haemoglobin's primary function.

I suppose you could say they are all components of oxygenated blood, or that haemoglobins contain iron and carry oxygen.

Haemoglobin : Haeme + globin.
Haeme - Iron part. Globin - Protein part.
It is present as a major part in RBC.
This is responsible for the transport of oxygen to the cells and also for the transport of carbon di oxide from the cells to the lungs. They are the most important compound in our body...

haemoglobin is a molecule found in the blood, it contains an atom of iron and it is used to transport oxygen through the blood.

haemoglobin is a globular protein of quaternary structure. normal adult haemoglobin is made of 4 polypeptide chains. Each polypeptide contains a non-protein haem group which is composed of an iron atom held in a heterocyclic ring.

The haem group is where oxygen binds to, to form oxyhaemoglobin. Thus, a normal adult haemoglobin can carry up to 4 oxygen atoms.

Hemoglobin is a relatively large protein molecule found in red blood cells ( also called red blood corpuscles or erythrocytes). The molecule contains the element iron (Fe) and needs this element to perform its job. We get this element from iron rich foods.
Hemoglobin in the erythrocytes enables the transport of oxygen to the body cells and the transport of some carbon dioxide waste from the body cells.

Hemoglobin is the iron-carrying protein found in red blood cells that binds to oxygen. The principal function of hemoglobin is to combine and transport oxygen from the lungs following inhalation, and then deliver it to all body tissues, where it is required to provide energy for the chemical reactions of all living cells. Carbon dioxide (produced as the waste product of these reactions) is transported to the lungs in the blood and is then released when we exhale.

sure there is an oblique relation, because iron deficiency motives unusual shapes for the pink blood cells, and those cells wont shipping oxygen at a sturdy fee to the mind so it truly is going to reason a headache. and to extend the iron degrees in the blood you're taking iron supplements, multivitamin and devour spinach. (those are the three major and effortless factors)

simple my dear.
-u need iron to make haemoglobin
-u need haemoglobin to transport oxygen from the lungs the the tissues.

There is iron in the hemoglobin. Hemoglobin is what transports oxygen within the red blood cell to parts of the body.
