Hemoglobin and albumin are both essential proteins in the bloodstream that provided a variety of functions. Hemoglobin are proteins in red blood cells that help transport oxygen through the bloodstream and carbon dioxide back so the body can undergo aerobic respiration. It has an essential component, heme, which contains an iron atom that allows hemoglobin to have an affinity for oxygen and carbon dioxide.
Hemoglobin, the main component of the red blood cell, functions in the transportation of oxygen and CO2. Hemoglobin consists of 1 molecule of globin and 4 molecules of heme (each containing 1 molecule of iron in the ferrous state). Globin consists of 2 pairs of polypeptide chains. In the hemoglobin molecule, each polypeptide chain is associated with 1 heme group; each heme group can combine with 1 molecule of oxygen or CO2. Hemoglobin carries oxygen from places of high oxygen pressure (lungs) to places of low oxygen pressure (tissues), where it readily releases the oxygen.
