What does haemoglobin contain? Best Answer: Haemoglobin is a protein and all proteins contain the elements Nitrogen, Hydrogen, Carbon and Oxygen only but Haemoglobin also contains Iron.emoglobin or haemoglobin is the iron-containing oxygen-transport metalloprotein in the red cells of the blood in mammals and other animals. The molecule consists of globin, the apoprotein, and four haem groups, an organic molecule with an iron atom. Source(s): wikipedia. Ed F · 9 years ago.

Blood urea nitrogen The liver produces urea in the urea cycle as a waste product of the digestion of protein. Normal human adult blood should contain between 6 to 20 mg of urea nitrogen per 100 ml (6–20 mg/ dL) of blood.Individual laboratories may have different reference ranges as the procedure may vary.o convert from mg/dL of blood urea nitrogen to mmol/L of urea, multiply by 0.357 (each molecule of urea having 2 nitrogens, each of molar mass 14g/mol) (BUN is the mass of nitrogen within urea/volume, not the mass of urea).

Blood Hemoglobin is the four-stranded protein molecule found in red blood cells that carries oxygen from the lungs to the individual body cells.emoglobin is the protein that is responsible for turning megakaryocytes into doughnut-shaped red blood cells. Hemoglobin is the protein that is either found in decreased amounts or totally absent in persons with hemophilia.

- In nodules where nitrogen-fixation is occurring, the plant tissues contain the oxygen-scavenging molecule, leghaemoglobin (serving the same function as the oxygen-carrying haemoglobin in blood). The function of this molecule in nodules is to reduce the amount of free oxygen, and thereby to protect the nitrogen-fixing enzyme nitrogenase, which is irreversibly inactivated by oxygen. Some excellent images and discussion of these leguminous associations can be found at:

- Every blood cell contains a chemical called hemoglobin. The hemoglobin molecule contains a single atom of Iron. This Iron atom is in such an oxidation state and is presented i … n such a way that it has a weak affinity to oxygen molecules.xygen molecules are bound to the red pigment HEMOGLOBIN, a protein complex found exclusively in red blood cells. A very small amount of oxygen is also dissolved in the liquid … portion of blood, but hemoglobin carries the bulk of oxygen.

Hemoglobin In mammals, the protein makes up about 96% of the red blood cells' dry content (by weight), and around 35% of the total content (including water). Hemoglobin has an oxygen-binding capacity of 1.34 mL O 2 per gram, which increases the total blood oxygen capacity seventy-fold compared to dissolved oxygen in blood.emoglobin and hemoglobin-like molecules are also found in many invertebrates, fungi, and plants. In these organisms, hemoglobins may carry oxygen, or they may act to transport and regulate other things such as carbon dioxide, nitric oxide, hydrogen sulfide and sulfide.

Hemoglobin Hemoglobin (American) or haemoglobin (British) (/ˈhiːməˌɡloʊbɪn, ˈhɛ-, -moʊ-/[1][2][3]); abbreviated Hb or Hgb, is the iron-containing oxygen-transport metalloprotein in the red blood cells of all vertebrates[4] (with the exception of the fish family Channichthyidae[5]) as well as the tissues of some invertebrates.

Transport of oxygen in the blood The effect of carbon dioxide in the blood. Haemoglobin can also bind carbon dioxide, but to a lesser extent. Carbaminohaemoglobin forms. Some carbon dioxide is carried in this form to the lungs from respiring tissues. The presence of carbon dioxide helps the release of oxygen from haemoglobin, this is known as the Bohr effect. This can be seen by comparing the oxygen dissociation curves when there is less carbon dioxide present and when there is more carbon dioxide in the blood.

Adult and Foetal Haemoglobin Structure of Haemoglobin: Haemoglobin is an aggregation of four globular proteins (typically two alpha and two beta subunits), each with an embedded haeme group. Each haeme group allows the binding of an oxygen molecule.

Hemoglobin The name hemoglobin comes from heme and globin, since 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 presence of hemoglobin in blood increases the oxygen carrying ability of a litre of blood from 5 to 250 ml. Hemoglobin also plays a major role in the transport of carbon dioxide from the tissues back to the lungs.

- Hemoglobin is the main substance of the red blood cell. It helps red blood cells carry oxygen from the air in our lungs to all parts of the body. Normal red blood cells contain hemoglobin A. Hemoglobin S and hemoglobin C are abnormal types of hemoglobin.

Hemoglobin (Low and High Range Causes) Hemoglobin is the protein molecule in red blood cells that carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues back to the lungs. Hemoglobin is made up of four protein molecules (globulin chains) that are connected together. The normal adult hemoglobin (abbreviated Hgb or Hb) molecule contains two alpha-globulin chains and two beta-globulin chains. In fetuses and infants, beta chains are not common and the hemoglobin molecule is made up of two alpha chains and two gamma chains.

Hemoglobin Hemoglobin and hemoglobin-like molecules are also found in many invertebrates, fungi, and plants. In these organisms, hemoglobins may carry oxygen, or they may act to transport and regulate other things such as carbon dioxide, nitric oxide, hydrogen sulfide and sulfide.arbon dioxide binds to hemoglobin and forms carbaminohemoglobin. This decrease in hemoglobin's affinity for oxygen by the binding of carbon dioxide and acid is known as the Bohr effect (shifts the O 2 -saturation curve to the right).

Biochemistry/Proteins/Types of Protein Hemoglobin[edit] Hemoglobin is an iron-containing protein in the red blood cells that is responsible for the transport of oxygen from the respiratory organs (i.e. lungs) to the rest of the body (i.e. the tissues). Unlike myoglobin which consists of a single polypeptide chain, hemoglobin consists of 4 polypeptide chains.
