Urea. It is measured by the level of BUN (blood urea nitrogen).
Excess nitrogen is made into uric acid and excreted.

Amino Acid
It's found in amino acid and nucleic acid
In amino acid and nucleic acid
no, it does not contain any amino-group, not even nitrogen.
Amino acids
Glycerol is produced from the breakdown of lipids which are fats or oils
Access aminp acids cannot be stored and is either broken down into nitrogen of converted to storable fats and carbohydrates by the liver. Nitrogen is highly toxic and is excreted in the urine, not stored in the liver.
One letter accounts for one nitrogen base, which is part of a codon, which codes for one amino acid.
Proline has an alpha nitrogen in a ring.
The amino group of an amino acid contains the elements Nitrogen and Hydrogen. By itself, it is not toxic to cells. But after deamination where the amino group is removed from the amino acid, the amino group is then converted into ammonia. Ammonia is toxic to cells, and also contains Nitrogen and Hydrogen, but it has a different chemical formula from the amino group.
