A pyrimidine nucleotide is composed of a pyrimidine base, a sugar (ribose or deoxyribose) and at least a phosphate group. Examples of different forms of pyrimidine nucleotide structures are uridine-5′-monophosphate (5′-UMP usually abbreviated as UMP) (44) and orotidine-5′-monophosphate (5′-OMP) (45), an intermediate of the de novo pyrimidine biosynthesis.
