Researchers at the BSC and the IRB Barcelona unveil crucial information about the protein transporter of oxygen, which opens up the possibility to optimize its function by introducing modifications. The transport of oxygen in blood is undertaken by hemoglobin, the largest component of red blood cells. This protein collects oxygen in respiratory organs, mainly in the lungs, and releases it in tissues in order to generate the energy necessary for cell survival.
hemoglobin (hÄËmÉglÅËbÄ­n) [ key ], respiratory protein found in the red blood cells (erythrocytes) of all vertebrates and some invertebrates. A hemoglobin molecule is composed of a protein group, known as globin, and four heme groups, each associated with an iron atom.In the lungs, each iron atom combines reversibly with a molecule of oxygen. Each hemoglobin molecule also has attached a single cysteine amino acid, which attracts nitric oxide from the lungs. hemoglobin molecule is composed of a protein group, known as globin, and four heme groups, each associated with an iron atom.
