Breath. Respiratory factor

you are: Breath

As Respiratory factor (RQ) is called the relation of quantity allocated СО2 to quantity absorbed О2 at oxidation of the given substratum to СО2 and Н2O. When as a substratum serve sugar, the respiratory factor is equal to unit, for example:

However, when a substratum role play lipidy, fibers and other connections with high degree of restoration, respiratory factor it appears less units, for example:

And on the contrary, for substrata with lower, than at Sugars, restoration degree the respiratory factor exceeds unit, for example:

Having defined respiratory factor of the given fabric experimentally, i.e. In parallel having measured changes in maintenance СО2 and О2, it is possible to receive representation about degree - oxidations of split connections. it is necessary to consider, however, that similar definitions can conduct and to incorrect conclusions if the nature of respiratory process is not quite clear. It is known, for example, that partial oxidation of sugars to pirovinogradnoj acids is made with oxygen absorption, but without allocation СО2 whereas at the subsequent dekarboksilirovanii, the leader to formation the Acetyl-soa, used for synthesis of fat acids, СО2 is allocated, but simultaneous absorption О2 does not occur. it is clear in such a manner that definition of respiratory factor allows us to judge the nature of an oxidised substratum only in the event that this substratum is oxidised completely - to СО2 and Н2O.
