orotic acid उदाहरण वाक्य

उदाहरण वाक्य

1. "' 4, 5-Dihydroorotic acid "'is a derivative of orotic acid which serves as an intermediate in pyrimidine biosynthesis.
2. An individual with untreated OTC deficiency will show decreased citrulline and arginine concentrations ( because the enzyme block is proximal to these intermediates ) and increased orotic acid.
3. "' Orotidine "'is a nucleoside formed by attaching orotic acid to a ribose ring via a ?-N 1-glycosidic bond.
4. PRPP transferase catalyzes both the ribosylation and decarboxylation reactions, forming UMP from orotic acid in the presence of PRPP . It is from UMP that other pyrimidine nucleotides are derived.
5. When this induced enzymatic block is combined with reduced physiologic enzyme activity as seen in heterozygotes, the elevation of orotic acid could be used to differentiate heterozygotes from unaffected individuals.
6. This biochemical phenotype ( increased ammonia, low citrulline and increased orotic acid ) is classic for OTC deficiency, but can also be seen in neonatal presentations of ornithine aminotransferase deficiency.
7. Tricreatine Orotate is a molecule of creatine bonded to orotic acid, a precursor of the nucleic acids that are used for DNA construction that increases the amount of carnosine in muscle cells.
8. In addition to the characteristic excessive orotic acid in the urine, patients typically have megaloblastic anemia ( UMP synthase deficiency ) which cannot be cured by administration of vitamin B12 or folic acid.
9. Orotic acid also enhances the formation of creatine phosphate, a source of energy converted to adenosine triphosphate ( ATP ) while the muscle is resting, as well as supporting muscle-protein synthesis.
10. IMC has also proven effective in accomplishing enzymatic assays for orotic acid in milk ( Anastasi et al . 2000 ) and malic acid in fruits, wines and other beverages and also cosmetic products ( Antonelli et al . 2008 ).
