Purine metabolism refers to the biochemical processes that break down and synthesize purines, which are essential components of DNA and RNA. Purines, such as adenine and guanine, are vital for cellular functions, including energy transfer and signaling. The body can obtain purines from dietary sources or recycle them from cellular breakdown, ensuring a steady supply for various biological activities. The breakdown of purines leads to the production of uric acid, which is excreted in urine. An imbalance in purine metabolism can result in conditions like gout, where excess uric acid crystallizes in joints, causing pain and inflammation. Understanding this metabolism is crucial for managing related health issues.
