Haemoglobins are iron-containing and oxygen-transporting metalloproteins that are found within the red blood cells of vertebrates (apart from one particular kind of fish family). Haemoglobins in the blood transport oxygen away from the lungs or gills, to all other parts of the body. It then releases oxygen for cell use, and collects carbon dioxide to take back to the lungs. This is the function of the haemoglobin within the body.
In mammals, the haemoglobin protein makes up around 97% of the red blood cell’s dry content. It also makes up around 35% of all content, including water. It has an oxygen binding capacity of exactly 1.34 ml 02 per gram of haemoglobin. This increases the total blood oxygen capacity by seventy, compared to the dissolved oxygen found within the blood. Mammalian haemoglobin molecules are able to carry up to four oxygen molecules.
The protein is also involved with the transportation of a number of other gases, too. It is able to carry some of the body’s respiratory carbon dioxide car carbaminohaemoglobin, whereby CO2 is carried to the globin protein. The protein molecule is also able to carry the important and necessary regulatory molecule ‘nitric oxide’, releasing it at the same time as it releases oxygen.
Haemoglobin will also be found outside of the red blood cells, and the progenitor lines. Other cells in the body that contain haemoglobin includes the A9 dopaminergic neurons within the substantia snigra, alveolar cells, macrophages and the mesangial cells within the kidney. In these particular tissues, haemoglobin is able to carry a non oxygen carrying function. This function is acting as an antioxidant, and regulating the iron metabolism.
Haemoglobin is an essential protein found within the body and will be measured by doctors if you are suffering from different kinds of medical problems. There will always be a way of increasing the amount or regulating the amount within the body.
