The normal concentration of uric acid in the serum of adults is in the range of 3-7 mg / dl. ø each helical turn of z dna contains 12 nucleotides 6 dimers. Most disorders of purine metabolism are expressed by a considerable variation in serum urate concentration and urinary uric acid excretion, since uric acid is the final product of purine metabolism in human beings (see Fig. Disorders of the hexose monophosphate shunt. For example, they are: • Substrates (building blocks) for nucleic acid biosynthesis and repair, • The main storage form of “high energy phosphate”, • Components of many “so-called” co-enzymes (NAD, NADP, FAD, CoA), • Components of many activated metabolic intermediates (such as UDPG, SAM), 5% 15% 30% 50% More Content Videos 3D Models News SOCIAL MEDIA Loading … HYPERURICEMIA AND GOUT Uric acid is the end product of purine metabolism in humans.
