A purine is a heterocyclic aromatic organic compound. It consists of a pyrimidine ring fused to an imidazole ring. Purines, which include substituted purines and their tautomers, are the most widely occurring nitrogen-containing heterocycle in nature.Purines and pyrimidines make up the two groups of nitrogenous bases, including the two groups of nucleotide bases.wo of the five bases in nucleic acids, adenine (2) and guanine (3), are purines. In DNA, these bases form hydrogen bonds with their complementary pyrimidines thymine and cytosine, respectively.
A low-purine diet is a meal plan based on foods that are low in purine content. Purine is a substance that is found in foods and is produced naturally by the body. Purines are broken down by the body and changed to uric acid. The kidneys normally filter the uric acid, and it leaves the body through the urine. However, people with gout sometimes have a buildup of uric acid in the blood.
