|
the breaking down of proteins into polypeptides
|
|
|
the stripping of the nitrogen amine group from amino acids
|
|
|
the conversion of ammonia to urea
|
|
|
the breakdown of polypeptides by carboxypeptidase
|
Explanation:
Detailed explanation-1: -the removal of the amino nitrogen occurs during the process of transamination and oxidative deamination. Increased deamination results in an increased production of ammonia which is consumed in the urea cycle. Urea, a hydrophilic non-toxic compound, is excreted by the kidneys into the urine.
Detailed explanation-2: -What is Deamination of Amino Acids? The process of removing an amino group from a molecule is called deamination, when the amino group is changed into ammonia. The enzyme that stimulates this action is called deaminases. Deamination principally occurs in the liver; however, glutamate is also deaminated in the kidney.
