Ultimately the nitrogen is excreted, mostly as urea.Ī heterogeneous condition associated with other cerebral malformations, metabolic disorders, and degenerative diseases beginning in fetal life. The gut takes up glutamine released by these organs where it is an energy source. Ammonia that escapes the action of ammonia-utilizing enzymes in the liver or is released into the circulation from systemic metabolic processes is metabolized largely to glutamine in the extrahepatic organs: brain, skeletal muscles, heart, adipose tissue, and lungs. Gut-derived ammonia in the liver is converted largely to urea and to a lesser extent, glutamine. Even in the absence of bacteria in the intestine, ammonia is released by enzymatic hydrolysis of urea. Colon bacteria synthesize one-third to one-half of intestinal ammonia, and the rest comes from metabolic products and to some extent from the reabsorption of nutritional ammonia. Two-thirds of the ammonia comes from the gut from precursors of glutamine and urea. In catabolism muscular ammonia is in the foreground, and the purine nucleotide cycle in muscles and other tissues plays an important role.
