GOOD De-Novo Pathway; Salvage Pathway (also called Dust-bin Pathway) De Novo Purine Synthesis. Adenine 2. Purine and pyrimidine nucleotides are synthesized by both de novo and salvage pathways (Figures 46-1 and 46-2).The de novo pathways create these complex phosphorylated molecules from simple precursors, such as CO 2, glycine, and glutamine, in stepwise fashion, whereas the salvage pathways serve the reuse of purine and pyrimidine bases of metabolic and dietary sources. Frequently, the level of uric acid in plasma is high and this condition can lead to gout (normal uric acid concentration, 3.6–8.3 mg/dL; levels as high as 9.6 mg/dL can occur without the generation of gout). Figure 3. Purines are primarily produced from endogenous sources and, in usual circumstances, dietary purines have a small role. It is a weak diprotic acid with p Ka values of 5.75 and 10.3.
