Purine nucleotide synthesis occurs by two pathways :
1.De novo synthesis
2.Salvage pathway
Liver is the major site of purine nucleotide biosynthesis (de novo).
Certain tissues cannot synthesize purine nucleotides by de novo patyway, e g. brain, erythrocytes and polymorphonuclear leukocytes.
These are dependent on salvage pathway for synthesis of purine nucleotides by using exogenous purines, which are formed by degradation of purine nucleotides synthesized in liver.
