METABOLIC FATE OF THE FUMARATE RELEASED FROM THE PURINE NUCLEOTIDE CYCLE Similar to the urea cycle, the carbon skeleton of aspartate leaves the purine nucleotide cycle as fumarate in the cytosol.
The urea cycle and the citric acid cycle are independent cycles but are linked. One of the nitrogen atoms in the urea cycle is obtained from the transamination of oxaloacetate to aspartate. The fumarate that is produced in step three is also an intermediate in the citric acid cycle and is returned to that cycle.
