Male rats gavaged with 1000 umol (15)N-ammonium chloride each day for 5 days excreted low, but significant amounts of excess (15)N-NO3- in urine on the 5 days of treatment & on the 5 subsequent days. An in vitro chemical model system was used to demonstrate that oxidation of ammonia to NO3- by the hydroxyl radical at physiological pH is chemically feasible. These results are consistent with the hypothesis that ammonia is oxidized to NO3- in vivo by a nonenzymic process which involves active O species such as the hydroxyl radical.

... EXCRETION IS PRIMARILY BY WAY OF KIDNEYS, BUT A NOT INSIGNIFICANT AMT IS PASSED THROUGH SWEAT GLANDS.

... Ammonium toxicity induced by ammonium acetate administration in frogs led to variable excretion of ammonia and urea into the medium. When 11.45 mM/kg body wt of ammonium acetate was administered, ammonia excretion increased while urea excretion decreased. When 4.17 mM/kg body wt of ammonium acetate was administered, the urea excretion increased while NH3 excretion decreased.

Ammonium hydroxide penetrates fastest, followed by sodium hydroxide, potassium hydroxide, and finally calcium hydroxide.

BeschreibungAmmonium hydroxide is a colorless, liquid solution with a characteristic and pungent odor. It is ammonia combined with water. Ammonia (NH3) is a compound consisting of nitrogen and hydrogen. Both ammonia and ammonium hydroxide are very common compounds, found naturally in the environment (in air, water, and soil) and in all plants and animals, including humans. Ammonia is a source of nitrogen, an essential element for plants and animals. Ammonia is also produced by the human body &ndash; by our organs and tissues and by beneficial bacteria living in our intestines.Ammonia plays an important role in protein synthesis in the human body. In brief summary, all living things need proteins, which are comprised of some 20 different amino acids. While plants and microorganisms can synthesize most amino acids from the nitrogen in the atmosphere, animals cannot. For humans, some amino acids cannot be synthesized at all and must be consumed as intact amino acids. Other amino acids, however, can be synthesized by microorganisms in the gastrointestinal tract with the help of ammonia ions. Thus, ammonia is a key player in the nitrogen cycle and in protein synthesis. Ammonia also helps maintain the body's pH balance.

VerwendenAmmonium hydroxide is used as a cleaning agent and sanitizer in many household and industrial cleaners. Ammonium hydroxide is also used in the manufacture of products such as fertilizer, plastic, rayon and rubber. Aqueous ammonia is corrosive to aluminum alloys, copper, copper alloys, and galvanized surfaces. Aqueous ammonia is an excellent acid neutralizer.

DefinitionAmmonium hydroxide,NH40H, is a hydrate of anunonia and exists in crystalline form at -79°C. Normally, it is only found in an aqueous solution also known as aquaanunonia and anunonia water. It is prepared by dissolving NH3 inH20. Reagent grade anunonium hydroxide contains from 28 to 30% NH3 at 15.6 °C. Industrial sales specify the concentration of NH3 in solution in terms of specific gravity. Common concentrations are 20 °Be, which would bea concentration of 17.8% NH3 (specific gravity 0.933) and 26 °Be (specific gravity 0.897), or a concentration of 29.4% NH3. Ammonium hydroxide is an excellent medium for the reaction of NH3 (which becomes the NH4 radical in solution) with other compounds for the preparation of anunonium salts and other nitrogen-containing chemicals. It is an ingredientin deodorants, etching compounds, and cleaning and bleaching materials. Ammoniumhydroxide, as aqua ammonia, finds wide use as a neutralizing agent,because it is inexpensive and strongly alkaline.
