purines

Adenine and guanine

Purines are a class of organic compounds with a specific double-ring molecular structure.

In biochemistry, they're one of two types of nitrogenous bases that form the building blocks of DNA and RNA—adenine and guanine are purines, while cytosine and thymine are pyrimidines.

Purines also appear in foods like organ meats, shellfish, and beer; people with gout often restrict purine intake because the body breaks purines down into uric acid.
