A series of heterocyclic compounds that are variously substituted in nature and are known also as purine bases. They include adenine and guanine, constituents of nucleic acids, as well as many alkaloids such as caffeine and theophylline. Uric acid is the metabolic end product of purine metabolism.
Nitrogenous compounds (bases) that occur in nucleic acids (adenine and guanine) and their precursors and metabolites; inosine, caffeine, and theobromine are also purines.
A basic nitrogenous heterocyclic compound found in nucleotides and nucleic acids; it contains fused pyrimidine and imidazole rings. Adenine and guanine are examples.
These are waste products or metabolites of nucleoproteins. They are not recyclable and are broken down further to an excretable form, uric acid. High purine presence in a tissue signifies a recent high turnover in nucleoproteins from injury or cell death, which is why some purines, such as allantoin, will stimulate cell regeneration. Many plants contain allantoin, most noticeably Comfrey. Some foods are heavy purine producers and can elevate uric acid levels. These include organ meats, seafood, legumes, and such politically correct foods as spirulina, chlorella, and bee pollen. Caffeine and theobromine are purine based alkaloids and can mildly increase uric acid, but they pale beside algae, pollen, and glandular extracts from the chiropractor.
The end products of nucleated protein digestion that break down to form uric acid.
A nitrogen-containing substance derived from uric acid which is the parent compound of several biologically important substances.
A derivative of purine, especially either of the bases adenine and guanine, which are found in RNA and DNA.
A nitrogenous base that is an essential structural unit of DNA and RNA; it includes adenine and guanine.
Any of a group of nitrogen-containing compounds; some (adenine and guanine) are part of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) structure; some result from the digestion of proteins, and some are synthesized in the body.
A nitrogen-containing compound with a two-ring molecular structure. Examples of purines are adenine and guanine, which form the ‘nucleotides of nucleic acids, and uric acid, which is the end product of purine metabolism.
Parent compound of nitrogenous bases, including adenine, guanine, xanthine, caffeine, and uric acid. Purines (chemical formula C5H4N4) are the end products of nucleoprotein digestion, and are catabolized to uric acid, which is excreted by the kidneys. Adenine and guanine are synthesized within cells for incorporation into DNA and RNA.
A colorless crystalline compound, serving as a fundamental component of DNA. Uric acid is generated through the breakdown of purine within the body.
Purines are a set of nitrogen-containing compounds that the body synthesizes or forms during the digestion of specific proteins. Elevated purine levels can result in hyperuricemia, a condition associated with gout. Foods rich in purine include sardines, liver, kidneys, pulses, and poultry. Additionally, purine constitutes essential components of adenine and guanine, which are nucleotide bases present in the genetic materials DNA and RNA.
