Nucleotide metabolism mnemonic

Sources of atoms in the purine ring

The mnemonic

Glycine, Aspartate, Glutamine, CO2, Formate

What each word stands for

  • GlycineContributes C4, C5 and N7
  • AspartateContributes N1
  • GlutamineContributes N3 and N9
  • CO2Contributes C6
  • Formate (one-carbon folate)Contributes C2 and C8

Why it matters clinically

Antifolates and glutamine analogues block purine synthesis and are used in chemotherapy.

Where it stops being reliable

It names the sources but not the atom positions in detail beyond those listed.

Teaching aid, still awaiting independent review. Confirm facts in a standard source.
