ACTH, TSH, LH, FSH ammonium metabolism Ammonia absorbed from diet is bound to glutamine in liver(perivenous) by glutaminase. Glutamine is then released into the blood for use as nitrogen donor for protein synthesis or for neurotransmitter synthesis in nervous tissue (GABA). Excess ammonia (from protein catabolism) is converted to urea in liver and excreted in urine and feces(some of this is reabsorbed and enters ammonia metabolism again) 3) Purine/ pyrimidine metabolism Purines: G, A Pyrimidines: C, U, T Purine synthesis glutamine, CO2, aspartate, n10-formyl-THF, glycine.
