Difference between Ammonotelism, Ureotelism and Uricotelism (Ammonotelism vs Ureotelism vs Uricotelism)

 Ammonia, urea and uric acid are the main nitrogenous waste product in different animals. The major role of excretory system is the elimination of nitrogenous wastes. In animals, nitrogenous excretion is grouped into three categories based on the form in which nitrogenous wastes are removed;
1) Ammonotelism 2)Ureotelism and 3)Uricotelism

Difference between Ammonotelism, Ureotelism and Uricotelism:

Ammonotelism vs Ureotelism vs Uricotelism

Ammonotelism

1. Chief nitrogenous waste is ammonia.

2. Solubility: Easily  dissolves in liver cells by deamination of aminoacids.

3. Ammonia is formed by deamination of amino acids in liver cells.

4. Ammonia is very toxic

Ureotelism 

1. Chief nitrogenous waste is urea

2. It is less soluble in water.

3. Urea is formed in liver and is produced from an amino acid arginine. Arginase is the enzyme involved. 

4. Urea is less toxic

Uricotelism

1. Chief nitrogenous waste is uric acid

2. It is almost insoluble in water.

3. Potassium ureate reacts with water and carbon dioxide to form uric acid.

4. Uric acid has very low toxicity
