Purines are compounds containing nitrogen, which are made inside the cells of our body or are received from foods containing purine (exogenous) like red meat, organ meat and seafood. The compound then breaks down into uric acid. Generally, the acid passes from the liver and enters the bloodstream, which is later excreted from the body through urine. But when the quantity of the acid exceeds the normal level in the blood it may accumulate in the tissues and form crystals.
