[Effect of carbonic acid concentration in blood on content of keto-acids and redox state of nicotinamide coenzymes in rabbit tissues].
A rise in the level of carbonic acid in animal blood at practically unchanged pH causes an increase in the value of free [NAD+]/[NADH] and [NADP+]/[NADPH] ratios in the liver cells cytoplasm. The increase in the oxidizing power of the liver cells cytoplasm is observed against a background of a rise in both the total level of keto-acids in blood and concentration of pyruvate oxaloacetate and alpha-ketoglutarate in the liver and kidneys of animals. The level of lactate, glutamate and citrate in these tissues also grows. The level of ketonic bodies in blood of the animals with a higher concentration of carbonic acid is somewhat lower than that in the animals with a lower concentration of HCO3 and CO2 in blood.
