Carbonmonoxyhemoglobin

Carbon monoxide (carbon monoxide, CO ) is a colorless gas, a faint smell. Molecular formula CO, molecule The amount of 28.01. The melting point of 199 C. The boiling point 191 C. Slightly soluble in water, soluble in ammonia . In the air Gas Flame is blue. CO and oxygen mixture Combustion is easy Happen The explosion. CO is a common serious harm human body Healthy asphyxia Chemical poison. It is a product of incomplete combustion of various fuel. Civil small coal, industrial waste gas and exhaust are an important source of pollution CO. The harm of CO pollution on human health, mainly in it blood In hemoglobin (Hb) with the formation of carboxyhemoglobin (carboxy-hemoglobin, COHb), the Hb loss of oxygen ability . Serious CO poisoning When due organization Hypoxia caused death. Therefore, the concentration of COHb in blood Monitor Is of great significance in the aspects of health care.
Carbonmonoxyhemoglobin
Carbon monoxide hemoglobin Carboxyhemoglobin hemoglobin and carbon monoxide (CO) conjugates. The same with oxyhemoglobin, Fe atom is 2 price, and CO, 4 N, blood porphyrin prion histidine residues covalently bound air into eight structure. Hemoglobin and CO affinity for O2 than the affinity, so the blood such as invasive CO, hemoglobin even if combined with O2, by CO to O2 power will replace the lost hemoglobin oxygen transport. This is the so-called carbon monoxide poisoning (carbon monoxide intoxic-ation). The maximum absorption peak of carbon monoxide hemoglobin was 570 nm and 542 nm. Red has more red than oxyhemoglobin. The other heme can often combine with CO to form the same compound. Carbon monoxide heme protein has been characteristic of photodissociation. This is the characteristic of it.
It should be mentioned that a cherry red carbon monoxide poisoning patient's skin mucous membrane, expression and general hypoxia cyanosis is different, this is because the carbonylhaemoglobin color is cherry red, so at the skin and mucous membranes was also reflected in this color -
The presence of carbon monoxide poisoning, blood carboxyhemoglobin, so Shiban was cherry red;
