Answer:
Purine breakdown results in the production of urate, or uric acid (either from the diet or from the normal breakdown of cells in the body). The kidneys eliminate uric acid, which is then eliminated in the urine and feces.
Explanation:
Concept(s):
Urate is a salt of urate acid.
Uric acid is a compound, C5H4N4O3, present in mammalian urine in small amounts, and the principal nitrogenous component of reptiles and birds. that in form of its salts occurs in the joints in gout and as the major constituent of kidney works.
More context:
Of the four major macromolecules in biological systems, both proteins and nucleic acids contain nitrogen. Nitrogen-containing macromolecules undergo catabolism, or breakdown, during which carbon, hydrogen, and oxygen are released and stored as carbs and lipids.
A substance called uric acid resembles the purines present in nucleic acids. It tends to produce a white paste or powder and is insoluble in water. In contrast to processing other nitrogenous wastes like urea (from the urea cycle) or ammonia, the generation of uric acid entails a complicated metabolic route that is energy-intensive. However, it has the benefit of minimizing water loss and, hence, the requirement for water.
Additionally, urea and ammonia are less poisonous than uric acid. It just requires a minimal amount of water for excretion since it includes four nitrogen atoms. Out of solute, it precipitates and forms crystals. Through the action of the enzyme xanthine oxidase, uric acid is created from the purines xanthine and hypoxanthine.
