the Urea Cycle
The urea cycle (aka the ornithine cycle) is a cycle of biochemical reactions that produces urea (\(H_2NCONH_2\)) from ammonia (\(NH_3\)).
Amino acids lose their amine groups upon catabolism
These amine groups become toxic ammonia
Ammonia needs to be excreted, or it will impair cephalic metabolic activities
It gets converted into non-toxic urea in the hepatocytes
Urea is excreted in the urine
Steps:
Transamination
Oxidative Deamination
Nitrogen removal
