Ammonia

Ammonia is an end-product of deamination of amino acids. In vivo, it is physiologically produced, predominantly in the gastrointestinal tract, myocytes, lymphocytes, and the kidney. Ammonia is neurotoxic if it accumulates but, normally, it is metabolized to urea by hepatocytes, and to glutamine by myocytes and hepatocytes. Urea is excreted by the kidney, but can also diffuse into all tissues and body fluids. In the gastrointestinal tract, bacterial ureases produce ammonia from the urea. Significant formation of ammonia also occurs following hydrolysis of glutamine by glutaminase containing cells such as gastrointestinal epithelial cells and lymphocytes [1]. Evaluation of plasmatic ammonia is a prognostic test primarily performed in the clinical…

miles north of Stoughton. The train derailment occurred late Monday night just after the intersection with County Highway DD, about 15 miles outside of Madison. Eight tankers carrying a harmful chemical tipped over and some began leaking. The cause of the derailment remains unknown. Fourteen tankers are carrying the chemical anhydrous ammonia, which is extremely toxic to people, aquatic animals and classified as “dangerous for the environment” but the Environmental Protection Agency. Two…

Why is ammonia important? The primary use of ammonia (NH3) is to provide nitrogen atoms for plants so they are able to make amino acids, proteins, and other biologically important molecules. In order to provide the vast amount of food demanded by a growing industrialised population, more efficient agricultural techniques and larger scale farms must be employed. There exists some naturally occurring nitrogen fixing bacteria that are able to convert atmospheric N2 into the more useful form of NH3…

The synthesis of ammonia reaction is a quite a remarkable one. It does not occur spontaneously -- at least, not on Earth because of the relatively low temperatures here; it requires a catalyst to commence the reaction, instead. Additionally, the product of this reaction makes it possible for the Earth to sustain its population (that will be discussed later with the date). Ammonia is an extremely important part of people 's lives, and most do not realize that fact. In this paper, the data will…

Anhydrous ammonia is the target of methamphetamine (meth) producers after it spilled out the derailed train cars 10 days ago in Stoughton. Anhydrous ammonia is a key ingredient in the production of meth, the highly addictive, central nervous system stimulating drug. Meth has a high potential for abuse and dependence, and is very easy to make when utilizing anhydrous ammonia. Two tankers that remain at the crash site still have anhydrous ammonia inside of them. These tankers are now under…

Freshwater Treatment for Amoebic Gill Disease Freshwater treatment for AGD requires checking for few things before and during the treatment to carry out a successful and effective treatment. 1. Freshwater Source: The freshwater source should be checked for temperature, total ammonia nitrogen and ammonia percentage, pH, hardness, salinity and any harmful plankton. Temperature: Freshwater with temperature closer to the temperature that treating fish are being reared in is best choice. Colder…

In problem one, we were simulating an ammonia production by reacting nitrogen and hydrogen in a reaction called Haber process. Haber process is a very economic exothermic reaction to produce ammonia by reacting nitrogen and hydrogen using a metal catalyst in high pressure and temperature. Nitrogen was obtained from the air and therefore, some argon would be included in this simulation. On the other hand, hydrogen was obtained from the cracking of petroleum. The simulation process started where…

responsible for the production of the compound ammonia; which is accountable for the world’s consumption of natural gas (BBC, 2014). The Haber process is the method of synthesizing the compound of ammonia which is produced from Hydrogen (H2) and Nitrogen (N2) gas (Sinha, 2014). In 1909 a German named Fritz Haber developed the compound of ammonia, thus The “Haber” process was named after the physical chemist (AUS-e-TUTE, 2014). In 1918 Fritz Haber received the Nobel Prize for this method; in…

in water at standard temperature and pressure (NOAA). Nitrates are widely used in very large quantities as fertilizers in agriculture because of their readiness to decompose and release nitrogen for plant growth and because of their ready solubility ensuring that nitrate ions can be absorbed by plant root hairs. (NOAA). Nitrate compounds have a wide range of uses which rely on their activity as oxidizing agents, the presence of freely available nitrogen, or their high solubility (NOAA).…

in small amounts. Determining the presence of nitrate can be difficult due to the small amounts of nitrate in water. Nitrate can be found in rivers lakes and ground water. Nitrate nitrogen is the pre dominant form of nitrogen. A high level of nitrate present in water indicates that there was organic pollution but not recently. Plants and animals need nutrients like nitrogen for the formation of amino acids. Nitrogen cannot be used by aquatic plants in its molecular form. Nitrogen is converted…
