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.

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.

Hemoglobin, the major component of red blood cells, transports oxygen from the lungs to tissues throughout the body. It also carries some CO 2 back to the lungs. Hemoglobin consists of four units, each of which consists of a globin polypeptide chain bound to an iron-containing heme molecule.

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. I hope you have understood the short and simple calculation for finding the molar mass of Hemoglobin.

The binding of oxygen is affected by molecules such as carbon monoxide for example, from tobacco smoking , exhaust gas , and incomplete combustion in furnaces. Retrieved An Hb A 1c proportion of 6. This accomplishment earns him a share of the Nobel Prize in Chemistry. Acknowledgement We would like to thank Prof. Cytochrome Cytochrome b Cytochrome P Methemalbumin. Various factors such as low pH, high CO 2 and high 2,3 BPG at the level of the tissues favor the taut form, which has low oxygen affinity and releases oxygen in the tissues.

For example, it is typically tested before or after blood donation. Journal of Experimental Biology. A mostly separate set of diseases called thalassemias involves underproduction of normal and sometimes abnormal hemoglobins, through problems and mutations in globin gene regulation. A variant called leghemoglobin serves to scavenge oxygen away from anaerobic systems such as the nitrogen-fixing nodules of leguminous plants, preventing oxygen poisoning. Archived from the original on 14 April When hemoglobin combines with CO, it forms a very bright red compound called carboxyhemoglobin , which may cause the skin of CO poisoning victims to appear pink in death, instead of white or blue. PMID Lehninger Principles of Biochemistry , 3rd ed. This strain is transmitted to the remaining three monomers in the tetramer, where it induces a similar conformational change in the other heme sites such that binding of oxygen to these sites becomes easier. Edinburgh Medical and Surgical Journal. Essentials of Oxygenation: Implication for Clinical Practice. Hemoglobin consists of four units, each of which consists of a globin polypeptide chain bound to an iron-containing heme molecule. This elevation may be caused by congenital heart disease , cor pulmonale , pulmonary fibrosis , too much erythropoietin , or polycythemia vera.
