The Chemical Structure of Uric Acid

The animals that live mostly in lots of water, they don't need to repackage it into urea or uric acid. They just freely excrete it into the water constantly. And so I think these animals, I can't tell you the difference in chemical structure between urea and uric Acid. But we probably know that with birds and so forth, I mean, I have chickens and you can smell that ammonia smell. And that's in their poo, which you can also in some bird poos, you can see that whitening color.
