Purines are a type of organic compound that play a crucial role in the biochemistry of living organisms. They are one of the two classes of nitrogenous bases found in nucleotides, which are the building blocks of DNA and RNA. The two most common purines are adenine and guanine, which are essential for various cellular processes, including energy transfer and the synthesis of genetic material. In addition to their role in nucleic acids, purines are also involved in the production of ATP (adenosine triphosphate), the primary energy carrier in cells. Purines can be obtained from dietary sources, such as meat and fish, and are also synthesized by the body. Their metabolism is important for maintaining cellular functions and overall health.
