Detailed explanation-1: -The urea cycle is a process in which waste (ammonia) is removed from the body. When you eat proteins, the body breaks them down into amino acids. Ammonia is produced from leftover amino acids, and it must be removed from the body.
Detailed explanation-2: -Proteins break down into amino acids.
Detailed explanation-3: -The reaction by which urea decomposes has been studied extensively over the past century. In aqueous solution, urea decomposition yields cyanate and ammonium ions, (NH2)2CO → CNO− + NH4+. An elimination mechanism appears to be operative. Cyanate ion further readily undergoes conversion to CO2 and ammonia.
Detailed explanation-4: -Ammonia and carbon dioxide (CO2) react exothermically to produce the carbamate salt, which is then heated to form urea.
Detailed explanation-5: -Urea Formula Urea has four elements which are carbon, nitrogen, oxygen, and hydrogen. It has a molar mass of 60.06 g/mole and has two amide groups and a carbonyl group. The structural and chemical formula of urea is discussed in the following points.
