And what does a truly digital age imply for the ethics and social structures of ecosystem citizens? Age of Design. Ecosystems are about people, their activities and the fundamental human need to share and build emotional relationships.
Ammonia is a normal by-product of processing nitrogen in the body, and is excreted as waste in the urine, in healthy people. However, elevated blood ammonia levels can occur when the kidneys or liver are not working properly, allowing this waste to remain in the bloodstream, which can be poisonous to your cells.
When amino acids are burned as a fuel, ammonia (NH3] is the waste product. Ammonia must be carried to the liver, converted to urea and excreted by the kidneys. One of the penalties of amino acid excess is ammonia excess, a potential cause of body malfunction following a high protein meal. The blood measurement of urea nitrogen (BUN) shows the balance between urea production by the liver and excretion by the kidneys. The BUN rises in kidney failure and serves as a measure of ammonia or nitrogen. In liver disease, reduced ability to synthesize urea leads to ammonia accumulation.
