As illustrated in Figure 3.1, products of de novo biosynthesis pathways of purine, pyrimidine, and pyridine nucleotides are AMP and GMP, UMP and NaMN. Purine and pyrimidine ribonucleoside monophosphates are converted to ribonucleoside diphosphates and triphosphates as well as deoxyribonucleotides. These processes are common to both purine and pyrimidine nucleotides. The ribonucleoside mono- (NMP), di- (NDP) and triphosphates (NTP) are interconverted (see Figure 3.5), coupled with the various reactions shown in Sections 3.3.1, 3.3.2 and 3.4.
