2. | Formation of urea takes place in the liver. | Uric acid found in blood and it is a waste product. |
3. | The product of amino acid catabolism is Urea | The product of nucleic acid metabolism is Uric acid. |

5. | With the urine, urea can be excreted as liquid in humans. | Uric acid is excreted as solid with faecal matter in the bird and reptiles. |
6. | In the metabolic pathway of urea, production requires less energetic metabolic pathway when compared. | In the metabolic pathways in uric acid, production requires high energetic metabolic pathway. |
7. | Urea is basically not a bicyclic molecule. | Uric acid is basically a bicyclic molecule. |
8. | When urea excretes in high amount, water loss takes place. | When uric acid excretes in less amount, water loss takes place. |
