1. Metabolisme Asam Nukleat

4. Sintesis Nukleotida Purin

8. Pengendalian Biosintesis Purin

9. Salvage dari Purin Pada mamalia: Lesh-Nyhan Syndrome:
Adenin fosfo ribosiltransferase (APRT)
Adenin + PRPP AMP + PPi
Hipoksantin-guanin fosforibosiltransferase (HGPRT)
Hipoksantin +PRPP IMP + Ppi
Guanin + PRPP GMP + Ppi
Lesh-Nyhan Syndrome:
HPRT (-)
Neurologycal abnorm:
PRPP mengaktifkan Amidofosforibosil transferase (thp 2 synt IMP) Nukleotida purin  asam urat

10. Sintesis Nukleotida pirimidin

13. Toxoplasma gondii Toxoplasmosis Komplikasi:
blindness, neurological dysfunction, & death in immunocompromised individuals
Synthesis uracil de novo
Inhibitor to carbamoyl phosphate synthetase II

17. Degradasi Nukleotida

18. Jalur Utama Katabolisme Purin

22. Siklus nukleotida purin

24. Degradasi asam urat di berbagai organisme

30. Degradasi pirimidin
