Here the question is why are cyanosc and co carbon monoxide are toxic to humans? so co that is carbon monoxide co and cn minus why it is toxic to human.
00:36
Now for both this co and cn are very good ligands actually and can form complex with the iron and can interfere with the normal working of iron iron in the body.
01:03
In the body, fe2 plus iron is present in hemoglobin.
01:15
Hemoglobin is containing fe2 plus ion and co has about 200 times.
01:31
Carbon monoxide has about 200 times more affinity for the fe2 plus ion than oxygen.
01:42
So it can form a stable complex.
01:46
This complex is carboxyhemoglobin which is quite stable.
02:02
Hemoglobin which is quite stable and prevents normal uptake of oxygen when this carboxy hemoglobin is formed its tendency to accept oxygen will be very less thus depriving the body of needed oxygen which can result in unconsciousness it is depriving the need of the body for the oxygen and because of that what happens the result is suffocation or unconsciousness and even death because of less of oxygen and that is how the carbon monoxide is so toxic to human being and mechanism of toxicity of the cyanide ion, cn minus ion, is somewhat different...
