It is a heterocyclic aromatic organic compound. It consists of a pyrimidine ring fused to an imidazole ring.
A relatively small number of foods, however, contain concentrated amounts of purines. For the most part, these high-purine foods are also high-protein foods, and they include organ meats like kidney, fish like mackerel, herring, sardines and mussels, and also yeast. Because uric acid is formed from the breakdown of purines, low-purine diets are often used to help treat conditions like gout in which excessive uric acid is deposited in the tissues of the body. The average daily diet for an adult in the U.S. contains approximately 600-1,000 milligram Low-Purine Diet. Purines (PYUR-eenz) are found in many foods, especially organ meats, anchovies, mackerel, and sardines. Purines make up 15 percent of the uric acid found in the body. Too much uric acid can lead to problems, including kidney stones and gout. For this reason, a low-purine diet is recommended for people who have kidney stones, gout, and sometimes for people who have had an organ transplan A low-purine diet is an eating plan that limits foods that contain purine. Purines are a natural substance found in some foods. When your body digests purine, a waste product called uric (say: “yur-ick”) acid is produced. A buildup of uric acid crystals in the joints can cause a type of arthritis known as gout. Purines are found in many healthy foods. The purpose of a low-purine diet is not to completely avoid purines. Instead, the goals are to limit and monitor how much purine is in the food you eat, and to learn how your body responds when you eat different purine. a heterocyclic compound that is the nucleus of the purine bases (or purines) such as adenine and guanine, which occur in DNA and RNA, and xanthine and hypoxanthine. All living cells contain purines as purine nucleotides. purine. a heterocyclic compound that is the nucleus of the purine bases such as adenine and guanine (which occur in DNA and RNA) A low-purine diet or a purine-free diet may be required. Foods that are high in purines include anchovies and sardines; sweetbreads, liver, kidneys, and other organ meats; legumes; and poultry. The foods lowest in purine content include eggs, fruit, cheese, nuts, sugar, gelatin, and vegetables other than legumes. purine. a heterocyclic compound that is the nucleus of the purine bases (or purines) such as adenine and guanine, which occur in DNA and RNA, and xanthine and hypoxanthine. All living cells contain purines as purine nucleotid Purine by itself isn’t the problem. Purine is produced naturally in the body and is also found in certain foods. The problem is that purines break down into uric acid, which can form into crystals that deposit in the joints and cause pain and inflammation. This joint pain is referred to as gout, or a gout attack. Purines (specific chemical compounds found in some foods) are broken down into uric acid. A diet rich in purines from certain sources can raise uric acid levels in the body, which sometimes leads to gout. Meat and seafood may increase your risk of gout. Dairy products may lower your risk. 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. Two 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. This is called complementary base pairing. In RNA, the complement of adenine is uracil instead of thymine
