Molar mass of hemoglobin

Hemoglobin contains 0.

Hemoglobin haemoglobin , [a] Hb or Hgb is a protein containing iron that facilitates the transport of oxygen in red blood cells. Almost all vertebrates contain hemoglobin, [3] with the exception of the fish family Channichthyidae. A healthy human has 12 to 20 grams of hemoglobin in every mL of blood. Hemoglobin is a metalloprotein , a chromoprotein , and globulin. Hemoglobin also transports other gases. The molecule also carries the important regulatory molecule nitric oxide bound to a thiol group in the globin protein, releasing it at the same time as oxygen. Hemoglobin is also found in other cells, including in the A9 dopaminergic neurons of the substantia nigra , macrophages , alveolar cells , lungs, retinal pigment epithelium, hepatocytes, mesangial cells of the kidney, endometrial cells, cervical cells, and vaginal epithelial cells.

Molar mass of hemoglobin

The molar weight of hemoglobin is 64 kDa, so 1 mol of hemoglobin has a weight of 64, g, and 1 mmol has a weight of 64 g. According to this, the widely stated e. Moreover, it reflects the molar concentration of the hem groups as well as the molar concentration of iron bound to hemoglobin. The wrong molar concentration reference values in the literature may arise from the method by which the concentration is measured: automatic analyzer measure absorption of chemically modified hem groups and also make the final calculation with chemical properties e. Donald S. Young : Implementation of SI units for clinical laboratory data style: specifications and conversion tables. Annals of Internal Medicine Vol. Beutler Ernest, Waalen Jill : The definition of anemia: what is the lower limit of the normal blood hemoglobin concentration? Blood — J Clin Pathol 49 4 —4.

You can also refer to this one minute video which will show you the simple steps to calculate the molar mass of any compounds. Because the molar mass of any molecule or compound can be calculated by simply adding the molar masses of individual atoms. The molar mass of Carbon is The molar mass of Hydrogen is 1. The molar mass of Oxygen is Now, to calculate the molar mass of Hemoglobin, you just have to add the molar mass of all the individual atoms that are present in Hemoglobin.

The molecule also carries the important regulatory molecule nitric oxide bound to a thiol group in the globin protein, releasing it at the same time as oxygen. CBC News. Bulgin and Rosser. Toggle limited content width. Hemoglobin can bind protons and carbon dioxide, which causes a conformational change in the protein and facilitates the release of oxygen. Number of Fe atoms in gram of hemoglobin if it contains 0. Thank you! Philadelphia: Saunders Elsevier. Pharmacology, Fifth Edition. Non-synonymous mutations in the hemoglobin gene of multiple species living at high elevations Oreotrochilus, A. Inversely, at low partial pressures such as those present in respiring tissues , the low affinity, T tense state is favoured. William; Matsuda, Genji When red blood cells reach the end of their life due to aging or defects, they are removed from the circulation by the phagocytic activity of macrophages in the spleen or the liver or hemolyze within the circulation. Hummingbirds already expend a lot of energy and thus have high oxygen demands and yet Andean hummingbirds have been found to thrive in high altitudes.

In people acclimated to high altitudes, the concentration of 2,3-Bisphosphoglycerate 2,3-BPG in the blood is increased, which allows these individuals to deliver a larger amount of oxygen to tissues under conditions of lower oxygen tension. Heidelberger crystallizes oxygenated hemoglobin derived from horse and dog erythrocytes. Hummingbirds already expend a lot of energy and thus have high oxygen demands and yet Andean hummingbirds have been found to thrive in high altitudes. Archived from the original on February 5, Other anemias are rarer. Goddeeris; R Verheyen Hemoglobin deficiency is, in general, strictly distinguished from hypoxemia , defined as decreased partial pressure of oxygen in blood, [83] [84] [85] [86] although both are causes of hypoxia insufficient oxygen supply to tissues. Annual Review of Physiology. This shift promotes the binding of oxygen to the remaining three monomers' heme groups, thus saturating the hemoglobin molecule with oxygen. Number of Fe atoms in gram of hemoglobin if it contains 0.
