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.
Biochemical reactions in your body rapidly convert ammonia into less harmful molecules under normal conditions. Liver disease can cause ammonia levels to build up in your body. Your brain is normally protected from the low levels of ammonia in your body by the blood-brain barrier. Liver disfunction can cause ammonia levels to build up in your brain causing permanent brain damage, a condition known as hepatic encephalopathy.
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.
