Hematologic or hemoglobin (Hemoglobin in the spelling and abbreviated Hb or HGB) is the metallotrotein transporting iron-rich oxygen found in vertebrates of red blood cells and some invertebrates. Hemoglobin in the blood transports oxygen to the remaining part of the body (i.e. tissue) from the lungs or gills, where it releases oxygen for the use of cells.
About 97% of the dry part of red blood cells in the mammals and about 35% of the total part (including water) is made of protein.
Hemoglobin's ability to bind oxygen is between 1.36 and 1.37 ml O2 for the village against hemoglobin, which increases total blood oxygen capacity by seventy-fold.
Hemoglobin is also found in red blood cells and outside the projection lines that produce them. Other cells containing hemoglobin include A9 dopaminergic neuran of substantia nigra, macrophages, alveolar cells, and kidney mesangial cells. The role of hemoglobin in these tissues is in the form of the controller of antioxidant and iron metabolism rather than the transport of oxygen.
