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. 8 Actions. Pyrimidines may be synthesized de novo or recycled by a salvage pathway from normal catabolism. See also Approach to the Patient With a Suspected Inherited Disorder of Metabolism. Disorders of lipid metabolism. 12.15 Conclusions. The most commonly cited disorder, in the neurologic realm, is Lesch–Nyhan syndrome which presumably reflects its distinctive feature of self-mutilation. Disorders that involve abnormalities of nucleotide metabolism range from relatively common diseases such as hyperuricemia and gout, in which there is increased production or impaired excretion of a metabolic end product of purine metabolism (uric acid), to rare enzyme deficiencies that affect purine and pyrimidine synthesis or degradation. 13 points Disorders of purine and pyrimidine metabolism Ask for details ; Follow Report by Munawwarali5116 10.01.2019 Log in to add a comment What do you need to know? 168-3).
