Urea is used in fertilizers and is not considered toxic. Ammonia is toxic and is what converts readily to urea.
Urea is the less toxic in nature among the nitrogenous wastes where as Ammonia is 100,000 times toxic than urea.
too much salt is not good,urea is toxic
Ammonia is approximately 3 times more toxic than urea in terms of acute toxicity. Urea is less toxic to aquatic organisms compared to ammonia because it undergoes nitrification in water, converting it to nitrate which is less toxic.
Urea in urine is toxic.
NH4 is most toxic, in fact in mammals it is always transported in the form of glutamate, because it is so toxic. So if this is in reference to humans, that is the most likely answer. NH3 on the other hand is non toxic unless present in high concentrations for whatever reason (such as problems with excretion when it is converted to Urea
Urea is approximately 1.5 times less toxic than ammonia. This is because urea is less alkaline compared to ammonia, which can cause burns and irritation. However, both substances can be toxic if ingested in large amounts.
Ammonia is more toxic than urea because it is a strong alkaline compound that can disrupt cellular processes and cause damage to tissues and organs. Urea, on the other hand, is a less toxic waste product that is more easily excreted by the body in urine.
In the liver, urea is formed through the urea cycle, where ammonia and carbon dioxide are combined. This process primarily converts toxic ammonia, produced from protein metabolism, into urea, which is less toxic and can be safely excreted by the kidneys. The urea produced is then released into the bloodstream and ultimately excreted in urine.
Yes.
The liver produces urea when it metabolises (breaks down) proteins. This is done in hepatocytes (liver cells). Amino acids are first broken down into ammonia, which is highly soluble and toxic in the blood plasma, so ammonia is joined with carbon dioxide to make urea, this is less soluble and less toxic but a build up of urea is toxic in the blood. Urea is then transported in the blood to be filtered out by the kidneys.
Uric acid is generally less toxic than urea. Uric acid is more soluble in water and can be excreted as a solid, while urea is more toxic in high concentrations and must be diluted in water for excretion. Additionally, high levels of uric acid can lead to conditions like gout, whereas high levels of urea can contribute to kidney dysfunction.
It's the concentrated amount of urea that will kill, not the diluted amount that is added to silage. Urea will be diluted as it is added to silage, thus making it not toxic and edible for cattle to eat.
