  2. Hemoglobin - Wikipedia

    en.wikipedia.org/wiki/Hemoglobin

    Found in the muscle tissue of many vertebrates, including humans, it gives muscle tissue a distinct red or dark gray color. It is very similar to hemoglobin in structure and sequence, but is not a tetramer; instead, it is a monomer that lacks cooperative binding. It is used to store oxygen rather than transport it. Hemocyanin

  3. 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 ]

  4. Red blood cell - Wikipedia

    en.wikipedia.org/wiki/Red_blood_cell

    Red blood cells (RBCs), referred to as erythrocytes (from Ancient Greek erythros 'red' and kytos 'hollow vessel', with -cyte translated as 'cell' in modern usage) in academia and medical publishing, also known as red cells, [1] erythroid cells, and rarely haematids, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen (O 2) to the body tissues—via ...

  5. List of medical roots, suffixes and prefixes - Wikipedia

    en.wikipedia.org/wiki/List_of_medical_roots...

    This is a list of roots, suffixes, and prefixes used in medical terminology, their meanings, and their etymologies. Most of them are combining forms in Neo-Latin and hence international scientific vocabulary. There are a few general rules about how they combine.

  6. Carboxyhemoglobin - Wikipedia

    en.wikipedia.org/wiki/Carboxyhemoglobin

    The most extensively studied pathway is the metabolism of heme by heme oxygenase which occurs throughout the body with significant activity in the spleen to facilitate hemoglobin breakdown during erythrocyte recycling. Therefore heme can both carry carbon monoxide in the case of carboxyhemoglobin, or, undergo enzymatic catabolism to generate ...

  7. Hemoglobinemia - Wikipedia

    en.wikipedia.org/wiki/Hemoglobinemia

    A hemoglobin test measures the amount of hemoglobin in your blood. If a hemoglobin tests shows that a person's levels are below normal, it means they have a low red blood cell count, which is known as anemia. If the test shows higher levels than normal, it means they have hemoglobinemia. [citation needed] The normal range for hemoglobin is:

  8. Globin - Wikipedia

    en.wikipedia.org/wiki/Globin

    The most famous mutation in the globin fold is a change from glutamate to valine in one chain of the hemoglobin molecule. This mutation creates a "hydrophobic patch" on the protein surface that promotes intermolecular aggregation, the molecular event that gives rise to sickle-cell disease .

  9. Heme - Wikipedia

    en.wikipedia.org/wiki/Heme

    For example, the ability of hemoglobin to effectively deliver oxygen to tissues is due to specific amino acid residues located near the heme molecule. [13] Hemoglobin reversibly binds to oxygen in the lungs when the pH is high, and the carbon dioxide concentration is low. When the situation is reversed (low pH and high carbon dioxide ...
