What are pyrimidne bases used to build
A
nucleotides such as UMP, CMP and dTMP
2
Q
What happens in the pyrmidine salvage pathway
A
It recycles frr pyrimdine bases to form nucleotides
3
Q
How are pyrimidines degraded
A
- The pyrimidine ring is opened and broken down itno a highly solubel end product
4
Q
What is the end product of pyrimidine degredation+ what are they further broken down into

- B-alanine
B-aminoisobutyrate
-Then further brokenr down into Ammonia(Nh3 and CO2
