Final answer:
Cytidine monophosphate (CMP) is formed through a series of biosynthetic steps in the pathway of pyrimidine nucleotide synthesis.
Step-by-step explanation:
Cytidine monophosphate (CMP) is formed through a series of biosynthetic steps in the pathway of pyrimidine nucleotide synthesis. The synthesis begins with the formation of carbamoyl phosphate from carbon dioxide and ammonia, followed by the combination of carbamoyl phosphate with aspartate to form carbamoyl aspartate. Dihydroorotate is then formed from carbamoyl aspartate, which is subsequently converted to orotic acid. Orotic acid is attached to ribose to yield orotidylic acid, which is further decarboxylated to form uridylate. Uridylate is then converted to cytidine monophosphate (CMP), along with other pyrimidine nucleotides.
