Explanation:
Like we all know, the purine ring of IMP is made up of a nine membered compound . they are heterocyclic aromatic organic compound that consist of a pyrimidine ring fused to an imidazole ring. there are four nitrogen atoms and five carbon atom.
The ring is imidazole ring is made up of N1, C2, N3, C4, C5, C6 with the pyrimidine sharing C4 and C5 with the imidazole ring and also made up of N7, C8, N9.
the direct source of N1 is from aspartate
the direct source of C2 and C8 is from N 10 ‑formyltetrahydrofolate (THF)
N3 and N9 is derived from the amide group of Glutamine
C4, C5 and N7 is derivd from Glycine
C6 is derived from bicarbonate
