Nitrogen metabolism

Nitrogen metabolism is the synthesis, utilization or uptake, breakdown, and excretion of nitrogenous compounds in the body. The nitrogen metabolism encompasses nitrogen fixation, biosynthesis, and the breakdown of amino acids, purines, and pyrimidine. Since nitrogen-containing compounds are required for various life processes, nitrogen is an important element of life.
