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.
For example, the ability of hemoglobin to effectively deliver oxygen to tissues is due to specific amino acid residues located near the heme molecule. Hemoglobin binds oxygen in the lungs, where the pH is high and the CO2 concentration is low, and releases it in the tissues, where the situation is reversed.
