HUMAN NUTRITION

Detailed explanation-1: -is the primary mechanism by which mammals convert ammonia to urea. Urea is made in the liver and excreted in urine.

Detailed explanation-2: -The degradation product of urea, ammonia, is known to be toxic to all vertebrates. In neutral and acidic conditions, however, ammonia exists in the form of ammonium.

Detailed explanation-3: -Some of these chemical byproducts such as Ammonium and Urea can be harmful if they accumulate in the body and the kidneys excrete these waste products as chemicals in the urine.

Detailed explanation-4: -Amino acids may also be metabolized through the liver to form urea, which is then excreted in the urine. Body protein stores can be converted back to essential and nonessential amino acids or may be metabolized, forming waste products and ions, which, as previously detailed, are excreted in the urine.

Detailed explanation-5: -In animals, the nitrogenous wastes produced in the body are excreted in three forms which are ammonia, uric acid and urea. Ammonia is the most poisonous of all the different nitrogenous wastes and it is highly toxic in nature.
