Urea and uric acid are two different substances that were considered as same in normal use. Urea and uric acid are both waste substances of the body. This moves out of the body through excreta. Urea and uric acid also have other uses in society as chemicals. They are used as fertilizers and other useful items. So here is a discussion between the difference between these two terms, urea and uric acid.
Urea vs Uric Acid
The main difference between urea and uric acid is that they are completely different with different chemical formulas. The chemical formula of urea is (NH2)2 CO, whereas the chemical formula of uric acid is C5H4N4 O3. They also have different uses, like urea is used as fertilizers, but the level of uric acid is mainly used to diagnose health problems.
Urea is the main component of urine in humans. Urine is the excretion of humans in liquid form. Uric acid is also secreted as sweat from the human body. The chemical formula of urea is (NH2)2 CO. Urea is colorless, soluble in water, odorless, and neutral. It has widespread uses in fertilizer industries.
Uric Acid is the main component of the solid excreta of birds. Uric acid is also found in human excreta. The chemical formula of uric acid is C5H4N4 O3. This is an organic chemical. A prolonged deposit of uric acid is injurious to health. It can result in kidney failures and even death.
Comparison Table Between Urea and Uric Acid
| Parameters of Comparison | Urea | Uric Acid |
| Released as | As urine in human | Solid faecal matter in birds |
| Formula | (NH2)2 CO | C5H4N4 O3 |
| Uses | Has widespread uses | Has minimum uses |
| Excess amount reaction in humans | This leads to failure of the kidney. | This leads to kidney stones. |
| Prolonged deposit | Very much harmful for tissues | Less harmful to tissues as compared to uric acid |
What is Urea?
Urea is the main component of urine in humans. Urine is the excretion of humans in liquid form. Uric acid is also secreted as sweat from the human body. The chemical formula of urea is (NH2)2CO. Urea is colorless, soluble in water, odorless, and neutral. It has widespread uses in fertilizer industries.
Urea is an organic compound. It is considered a waste product in the human body. Urea is produced in the liver due to the breakdown of proteins in amino acids and then amino acids to urea. The kidney transfers the urea from the blood to the urine and gets it out of the body. The prolonged deposition of urea in kidney cells is very harmful to health. The increased level of urea in the body results in kidney failure, and a person may have to spend his rest life with dialysis.
Nowadays, urea is manufactured in industries. Synthetic urea is produced with the help of ammonia and carbon dioxide in both solid and liquid forms. In this synthetic urea, the nitrogen content is very high and appropriate to be used as fertilizers.
Nowadays, 90% of nitrogenous fertilizers contain urea as their main ingredient. In the soil, the urea breaks into ammonia. The bacteria present in the soil convert the ammonia into nitrates which are then taken by plants. Urea is highly soluble in water which makes it more preferable and easier to make solutions and spray them to the agricultural plants.
What is Uric Acid?
Uric Acid is the main component of the solid excreta of birds. Uric acid is also found in human excreta. The chemical formula of uric acid is C5H4N4O3. This is an organic chemical. A prolonged deposit of uric acid is injurious to health. It can result in kidney failures and even death.
Uric acid is formed in the body of humans due to the breakdown of a chemical called purines. The uric acid gets dissolved in the blood and then filtered by the kidney. This uric acid is thrown out of the body through urine. But due to our diet and lifestyle, some people have increased levels of uric acid in their bodies which is very harmful.
These extra uric acid form crystals and settle at the joints of knees, and other joints, resulting in pain. This medical condition is called arthritis. Prolonged deposition of uric acid in the kidney leads to kidney stones and other health problems. Uric acid deposition is more harmful as compared to urea deposition.
Uric acid is found in the solid fecal matter of birds and reptiles. They release it as a nitrogenous waste product from their body. This happens because the conversion of ammonia to urea needs more energy as compared to the conversion of ammonia to uric acid. To save energy, they convert ammonia to uric acid and discard it from their body.
Main Differences Between Urea and Uric Acid
- It is released with human excreta as urine in liquid form, whereas uric acid is found in the solid excreta of birds.
- The chemical formula of urea is (NH2)2 CO, and the chemical formula of uric acid is C5H4N4O3.
- Urea has widespread uses in the fertilizer industries. On the other hand, uric acid is only used in the diagnosis of health disorders.
- An excess amount of level of urea in humans leads to kidney failure, but the over level of uric acid leads to a kidney stone in humans.
- Prolonged deposition of urea in the tissues is comparatively less harmful than uric acid deposition.
Conclusion
Urea and uric acid both are waste products from the bodies of organisms. The urea is discarded from the body of humans as urine, and the uric acid is discarded as the solid fecal matter of birds. But uric acid is also found in humans. A high level of uric acid is more dangerous than a high level of urea. Both are very injurious to health.
So it should be taken into consideration to maintain the daily diet and the lifestyle to avoid these kinds of health problems. Urea is also manufactured in industries. This synthetic urea is highly used as fertilizers to provide an extra supplement to agricultural plants for their better growth.
