Which is not the precursor for the de novo purine biosynthesis?
amm1812

The correct option is (B) Lysine.

The precursors glutamine (N2 and N9), glycine (C4, C5, and N7), aspartate (N1), co2 (C6), and folate are used to create the purine ring (C2 and C8). All are precursors to the purine ring, with the exception of lysine.

How is Purine synthesized de novo?

  • In all cells, the cytosol is where purine biosynthesis takes place.
  • There are 11 steps that are catalyzed by enzymes that build the purine ring. Each enzyme includes several monomers because it is oligomeric.
  • The reaction does not release the intermediate products that are created. They are instead transported to the next enzyme in the process.
  • The biosynthesis process in the human body can provide the body's need for purine in metabolic processes. Clinical symptoms might become unpleasant if purine synthesis is inadequate or if biosynthetic routes are aberrant.
