2. Hemoglobin - Wikipedia

   en.wikipedia.org/wiki/Hemoglobin

   Hemoglobin in the blood carries oxygen from the respiratory organs (lungs or gills) to the other tissues of the body, where it releases the oxygen to enable aerobic respiration which powers an animal's metabolism. A healthy human has 12 to 20 grams of hemoglobin in every 100 mL of blood. Hemoglobin is a metalloprotein, a chromoprotein, and ...

3. Respiratory pigment - Wikipedia

   en.wikipedia.org/wiki/Respiratory_pigment

   Hemoglobin A is the “normal” hemoglobin, the variant of hemoglobin that is most common after birth. Hemoglobin A2 is a minor component of hemoglobin found in red blood cells. Hemoglobin A2 makes up less than 3% of total red blood cell hemoglobin. Hemoglobin F typically is only found in the fetal stage of development.

4. Hemoglobin A - Wikipedia

   en.wikipedia.org/wiki/Hemoglobin_A

   Hemoglobin A (HbA), also known as adult hemoglobin, hemoglobin A1 or α 2 β 2, is the most common human hemoglobin tetramer, accounting for over 97% of the total red blood cell hemoglobin. [1] Hemoglobin is an oxygen-binding protein, found in erythrocytes , which transports oxygen from the lungs to the tissues. [ 2 ]

5. Oxygen–hemoglobin dissociation curve - Wikipedia

   en.wikipedia.org/wiki/Oxygen–hemoglobin...

   Hemoglobin (Hb) is the primary vehicle for transporting oxygen in the blood. Each hemoglobin molecule has the capacity to carry four oxygen molecules. These molecules of oxygen bind to the globin chain of the heme prosthetic group. [1] When hemoglobin has no bound oxygen, nor bound carbon dioxide, it has the unbound conformation (shape). The ...

6. Carbaminohemoglobin - Wikipedia

   en.wikipedia.org/wiki/Carbaminohemoglobin

   When carbon dioxide binds to hemoglobin, carbaminohemoglobin is formed, lowering hemoglobin's affinity for oxygen via the Bohr effect. The reaction is formed between a carbon dioxide molecule and an amino residue. [12] In the absence of oxygen, unbound hemoglobin molecules have a greater chance of becoming carbaminohemoglobin.

7. Blood - Wikipedia

   en.wikipedia.org/wiki/Blood

   Hemoglobin has an oxygen binding capacity between 1.36 and 1.40 ml O 2 per gram hemoglobin, [23] which increases the total blood oxygen capacity seventyfold, [24] compared to if oxygen solely were carried by its solubility of 0.03 ml O 2 per liter blood per mm Hg partial pressure of oxygen (about 100 mm Hg in arteries).
