also gives its name to the wider class of molecules, purines, which include substituted purines and their tautomers. They are the most widely occurring

Purine metabolism refers to the metabolic pathways to synthesize and break down purines that are present in many organisms. Purines are biologically synthesized

beyond usual human consumption. Caffeine is a bitter, white crystalline purine, a methylxanthine alkaloid, and is chemically related to the adenine and

Purine analogues are antimetabolites that mimic the structure of metabolic purines. Nucleobase analogues Thiopurines such as thioguanine are used to treat

linked. Purines, however, are first synthesized from the sugar template onto which the ring synthesis occurs. For reference, the syntheses of the purine and

often refers to nucleotide salvage in particular, in which nucleotides (purine and pyrimidine) are synthesized from intermediates in their degradative

In humans, purines are metabolized into uric acid, which is then excreted in the urine. Consumption of large amounts of some types of purine-rich foods

reactions: HGPRTase functions primarily to salvage purines from degraded DNA to reintroduce into purine synthetic pathways. In this role, it catalyzes the
