Uric acid. Uric acid is a heterocyclic compound of carbon, nitrogen, oxygen, and hydrogen with the formula C5H4N4O3. It forms ions and salts known as urates and acid urates, such as ammonium acid urate. Uric acid is a product of the metabolic breakdown of purine nucleotides, and it is a normal component of urine. High blood concentrations of uric acid can lead to gout and are associated with other medical conditions including diabetes and the formation of ammonium acid urate kidney stones.

Confidence votes 36. A pure substance is matter that contains only one type of particle. Compounds consist of two or more elements, but they are still pure substances because there is only one particle-the elements are chemically joined. (For example, water is a compound made of 2 parts hydrogen to 1 part oxygen.).ure substances contain only one type of particles. Even though each molecule in a compound is made of different atoms and each atom is made of protons, neutrons and electrons â¦ , a single moleculs is a single particle and since compounds contain only one type of particle (its molecules), it is a pure substance.
