Eksempler på brug af UREA i en sætning

• active oxygen (peroxides, such as peracetic acid, potassium persulfate, sodium perborate, sodium percarbonate, and urea perhydrate),.
• Indirect calorimetry calculates heat that living organisms produce by measuring either their production of carbon dioxide and nitrogen waste (frequently ammonia in aquatic organisms, or urea in terrestrial ones), or from their consumption of oxygen.
• Wöhler is also known for seminal contributions in organic chemistry, in particular, the Wöhler synthesis of urea.
• Urea, also called carbamide (because it is a diamide of carbonic acid), is an organic compound with chemical formula.
• Organisms that cannot easily and safely remove nitrogen as ammonia convert it to a less toxic substance, such as urea, via the urea cycle, which occurs mainly in the liver.
• The urea breath test is a rapid diagnostic procedure used to identify infections by Helicobacter pylori, a spiral bacterium implicated in gastritis, gastric ulcer, and peptic ulcer disease.
• For historical reasons, the lab test measuring urea is known as "blood urea nitrogen" (BUN) in the US.
• Ammonia is toxic to the human system, and enzymes convert it to urea or uric acid by addition of carbon dioxide molecules (which is not considered a deamination process) in the urea cycle, which also takes place in the liver.
• Therefore, ornithine is a central part of the urea cycle, which allows for the disposal of excess nitrogen.
• It is a key intermediate in the urea cycle, the pathway by which mammals excrete ammonia by converting it into urea.
• Other organic carbonyls are urea and the carbamates, the derivatives of acyl chlorides chloroformates and phosgene, carbonate esters, thioesters, lactones, lactams, hydroxamates, and isocyanates.
• It plays an essential function for survival, neutralizing gastric acid by allowing urea to enter into periplasm via a proton-gated urea channel.
• In animals, the main excretory products are carbon dioxide, ammonia (in ammoniotelics), urea (in ureotelics), uric acid (in uricotelics), guanine (in Arachnida), and creatine.
• In contrast, mammalian OTC plays an essential role in the urea cycle, the purpose of which is to capture toxic ammonia and transform it into urea, a less toxic nitrogen source, for excretion.
• In land-dwelling animals, it is an intermediary metabolite in nitrogen disposal through the urea cycle and the synthesis of pyrimidines.
• A basic metabolic panel measures sodium, potassium, chloride, bicarbonate, blood urea nitrogen (BUN), magnesium, creatinine, glucose, and sometimes calcium.
• Folin described in the Journal some methods on how to analyze qualitatively and quantitatively some elements in the urine such as urea, uric acid, ammonia, creatine, and creatinine.
• It was revealed in 2007 that during the 1980s a contractor had dumped up to 1,000 pounds of urea at a pond on the TTR, resulting in the die-off of 61 horses in 1988.
• It can be defined as an excess in the blood of amino acid and protein metabolism end products, such as urea and creatinine, which would normally be excreted in the urine.
• By means of a countercurrent multiplier system, which uses electrolyte pumps, the loop of Henle creates an area of high urea concentration deep in the medulla, near the papillary duct in the collecting duct system.
• Primary hyperammonemia is caused by several inborn errors of metabolism that are characterised by reduced activity of any of the enzymes in the urea cycle.
• After the first German chlorine-gas attacks, Allied troops were supplied with masks of cotton pads soaked in urine; it had been discovered that the urea in the pad neutralised the chlorine.
• Petrochemical and energy related projects figured prominently, designed to utilise New Zealand's abundant natural gas to produce ammonia, urea fertiliser, methanol and petrol.
• This type of dialysis achieves the extracorporeal removal of waste products such as creatinine and urea and free water from the blood when the kidneys are in a state of kidney failure.
• Arginase catalyzes the fifth and final step in the urea cycle, a series of biochemical reactions in mammals during which the body disposes of harmful ammonia.
