disorders of nucleotide metabolism


Abnormalities in erythrocyte nucleotide metabolism are associated with hereditary nonspherocytic hemolytic anemia. Clinical manifestations of purine catabolism result from insolubility of uric acid. Nucleic acid metabolism is the process by which nucleic acids (DNA and RNA) are synthesized and degraded.Nucleic acids are polymers of nucleotides.Nucleotide synthesis is an anabolic mechanism generally involving the chemical reaction of phosphate, pentose sugar, and a nitrogenous base.Destruction of nucleic acid is a catabolic reaction. They produce ATP as the only source of energy and reducing power to maintain haemoglobin in its functional state and to counteract oxidative stresses. Purine Salvage Disorders. Other disorders, including those of adenine nucleotide metabolism also may have important implications for our understanding of the metabolic phenomena involved in exercise and recovery. ADA overexpression leads to an over-conversion of adenosine to inosine in erythrocytes depletes AMP, and therefore depletes ATP reserves. Disorders of Nucleotide Metabolism - Z.

Inborn errors of pyrimidine metabolism include disorders of pyrimidine synthesis and of pyrimidine nucleotide degradation. Purine nucleotide degradation refers to a regulated series of reactions by which human purine ribonucleotides and deoxyribonucleotides are degraded to uric acid in humans. MeSH Terms. Category: Hematologic disease. 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. PLAY. Two major types of disorders occur in this pathway. Nucleotide & nucleoside construction , purine nucleotide de novo synthesis process , pyrimidine nucleotide & bases degradation .
