Hemoglobin the iron gets recycled. This process also produces one molecule of carbon monoxide for every molecule of heme degraded. Heme degradation is one of the few natural sources of carbon monoxide in the human body, and is responsible for the normal blood levels of carbon monoxide even in people breathing pure air. The other major final product of heme degradation is bilirubin. Increased levels of this chemical are detected in the blood if red blood cells are being destroyed more rapidly than usual. Improperly degraded hemoglobin protein or hemoglobin that has been released from the blood cells too rapidly can
Hemoglobin Hopkins-2 Hemoglobin Hopkins-2 Hemoglobin Hopkins-2 (Hb Hop-2) is a mutation of the protein hemoglobin, which is responsible for the transportation of oxygen through the blood from the lungs to the musculature of the body in vertebrates. Generally, the mutation causes two abnormal α chains in the protein's structure. Within the chains, the mutation is the result of hemoglobin's histidine amino acid being replaced with aspartic acid in the protein's genetic sequence. This amino acid structure change occurs at residue 112. Additionally, within one of the mutated alpha chains, there are substitutes at 114 and 118, two points on the amino acid
