Uric acid
Humans also excrete a second nitrogenous waste, uric acid. It is the product of nucleic acid, not protein, metabolism. It is produced within peroxisomes.
uric acid
[Gk. ouron, urine]
An insoluble precipitate of nitrogenous waste excreted by land snails, insects, birds, and some reptiles.

URIC ACID IS USED BY ANIMALS THAT LAY EGGS
It is the least toxic of the 3 molecules. It precipitates out of solution in the egg thus it does not harm the developing embryo ...
uric acid the main nitrogenous excretory product in birds, reptiles, some invertebrates, and insects
uricotelic excretion Having uric acid as the chief excretory product of nitrogen metabolism; occurs in reptiles and birds.
Barbituric acid was first synthesised on December 4, 1864, by German researcher Adolf von Baeyer. This was done by condensing urea (an animal waste product) with diethyl malonate (an ester derived from the acid of apples).
(Science: chemistry) Derived from, or containing, sulphur; specifically, designating those compounds in which the element has a higher valence as contrasted with the sulphurous compounds; as, sulphuric acid. Sulphuric acid.
Purines from food (or from tissue turnover) are metabolized by several enzymes, including xanthine oxidase, into uric acid.
In heap leaching, a dilute sulfuric acid solution is percolated through crushed low-grade ore that has been stacked on an impervious pad.
acid rain The precipitation of sulfuric acid and other acids as rain. The acids form when sulfur dioxide and nitrogen oxides released during the combustion of fossil fuels combine with water and oxygen in the atmosphere.
purine base; basic compounds related in structure to uric acid; examples include adenine and guanine, which are bases and constituents of nucleic acids

kidney stones Crystallized deposits of excess wastes such as uric acid, calcium, and magnesium that may form in the kidney.

The circulatory system connection is obvious. Blood that circulates through the body passes through one of the two kidneys. Urea, uric acid, and water are removed from the blood and most of the water is put back into the system.
