This is because the oxygen in your body feels lonely at times, it need to find a pairing bond to nourish its life. So please support your oxygen atoms and find them a partner.

Is Heme iron absorbed better than nonheme iron?
Heme iron is much more absorbable than non-heme iron. Since the iron inanimal-based foods is about 40% heme iron and 60% non-heme iron, animal-basedfoods are good sources of absorbable iron. In contrast, all of the iron found in plantbasedfoods is non-heme iron. Meat, fish, and poultry also contain a special meatfactor that enhances the absorption of non-heme iron. Vitamin C (or ascorbic acid)also enhances the absorption of non-heme iron.
What iron - compound carries oxygen in the bloodstream?
Hemoglobin is a protein that contains an iron ion and assists in transporting oxygen in red blood cells. Hemoglobin also helps to transport carbon dioxide and nitric oxide.
What is the role of the Myoglobin?
Myoglobin is a protein found in muscle tissue of vertebrates that is iron- and oxygen-binding. It is a primary oxygen-carrying pigment of muscle tissues and is related to hemoglobin, but only found in the bloodstream after a muscle injury.
Do heme groups contain nitrogen?
Yes
Does hemoglobin contain the element cobalt?
No.In most vertebrates, the hemoglobin (or heamoglobin if you prefer) molecule is an assembly of four globular protein subunits. Each subunit is composed of a protein chain tightly associated with a non-protein heme group. Proteins are amino acid structures. The key elements of an amino acid are carbon, hydrogen, oxygen, and nitrogen. Each heme group contains one iron atom, that can bind one oxygen molecule. The heme in hemoglobin is Heme B which has the formula C34H32O4N4Fe. Note that Cobalt's chemical symbol is Co, and Co doesn't appear anywhere in hemoglobin's chemical formula.Note that there is a synthetic cobalt containing analog to hemoglobin. A coboglobin is a synthetic compound chemically similar to hemoglobin or myoglobin but using the metal cobalt instead of iron (hence the name).
How many molecules of oxygen can heme transport?
4 molecules of oxygen - one to each subunit on the heme
Which part o the hemoglobin molecule does carbon dioxide attach?
Hemoglobin refers to a red protein responsible for transporting oxygen in the blood of vertebrates. The part of the hemoglobin molecule that carbon attaches to is the heme molecule.
In red blood cells oxygen binds by interacting with what?
Heme
When red blood cells are broken down where are the heme from the hemoglobin converted to?
oxygen
What is the blood gas that is carried bond to heme of hemoglobin and dissolved in plasma?
Oxygen
What is the function of heme in hemoglobin?
Heme is what keeps iron from rusting in our blood, which combines with globin to make hemoglobin, which is the thing in our red blood cells that carries oxygen.
Each heme contains an atom of iron and can transport one molecule of oxygen?
true
What does the hemoglobin in blood contain?
Hemoglobin is made up of heme and globular protein. The heme contains iron inside a ring of carbon, hydrogen, nitrogen and oxygen molecules. The protein chains are complex helical structures.
What component in the plasma of red blood cells carries oxygen molecules to the somatic Cells?
The heme group of hemoglobin.
What is the role of heme in cell metabolism of immature red blood cells?
Heme is the featured component of hemoglobin. Hemoglobin is the red pigment that gives red blood cells their characteristic color and their essential ability to transport oxygen.
In order for oxygen to be carried on the red blood cell the iron must be in the?
The name hemoglobin is derived from the words heme and globin, reflecting the fact that each subunit of hemoglobin is a globular protein with an embedded heme or iron group.
If a patient has low Red Blood Cells count the oxygen carrying capacity decreases why?
because one of red blood cell function is to carry oxygen this is because it is made up of a thin membrane that allows oxygen and carbon dioxide to diffuse in and out of the cell. RBC's are also called erythrocytes and are made up of a substance called hemoglobin, this makes up 95% of the RBC. The oxygen carrying hemoglobin molecule has 4 subunits each containing a heme portion. This heme portion is where iron is present. A property of heme is that it can bind to oxygen or reversibly releasing oxygen. This gives it the ability to carry oxygen from the lungs yet release it during circulation in the organs etc. for cell metabolism.
