Urea, also known as carbamide, is an organic compound with the
chemical formula CO(NH2)2. This amide has two NH2 groups joined by
a carbonyl (C=O) functional group.
Urea serves an important role in the metabolism of
nitrogen-containing compounds by animals and is the main
nitrogen-containing substance in the urine of mammals. It is a
colorless, odorless solid, highly soluble in water, and practically
non-toxic (LD*0 is *5 g/kg for rats). Dissolved in water, it is
neither acidic nor alkaline. The body uses it in many processes,
most notably nitrogen excretion. The liver forms it by combining
two ammonia molecules (NH3) with a carbon dioxide (CO2) molecule in
the urea cycle. Urea is widely used in fertilizers as a source of
nitrogen and is an important raw material for the chemical
industry.
Friedrich Whler's discovery in ***8 that urea can be produced from
inorganic starting materials was an important conceptual milestone
in chemistry. It showed for the first time that a substance
previously known only as a byproduct of life could be synthesized
in the laboratory without biological starting materials,
contradicting the widely held doctrine of vitalism.
