ammonia

 [ah-mo´nyah]
a colorless alkaline gas, NH3, with a pungent odor and acrid taste, and soluble in water.
ammonia N 13 ammonia in which a portion of the molecules are labeled with 13N; used in positron emission tomography of the cardiovascular system, brain, and liver.

am·mo·ni·a

(ă-mō'nē-ă),
A colorless volatile gas, NH3, highly soluble in water, capable of forming a weak base, which combines with acids to form ammonium compounds.
[fr. L. sal ammoniacus, salt of Amen (G. Ammōn), obtained near a temple of Amen in Libya]

ammonia

Biochemistry
An irritating, water-soluble, strongly basic, colourless gas, which is lighter than air.
 
Industry
Ammonia (NH3) is used in explosives, fertilisers, refrigerants and household cleaning solutions.
 
Physiology
NH3 is produced in the liver, intestine and kidneys as an end-product of protein metabolism; the liver converts ammonia into urea, which is then excreted by the kidneys; in liver disease this conversion is decreased, resulting in increased serum ammonia. Serial measurement of ammonia is used to follow progression of hepatic encephalopathy in Reye syndrome and other conditions.
 
Ref range
15–49 µg/dL.
 
Abnormal values
Increased hepatic coma, Reye syndrome, severe CHF, GI haemorrhage, erythroblastosis fetalis, drugs (e.g., diuretics and antibiotics).

ammonia

A substance produced when AMINO ACIDS are broken down. Ammonia is converted by the liver into urea and excreted in the urine. Urea can be broken down by bacterial enzymes to release ammonia. This may be a cause of nappy rash in babies.

ammonia

a colourless gas, which is the main form in which nitrogen is utilized in living cells. Formula: NH3.
