WebElevated orotic acid may be observed in other conditions with hyperammonemia such as lysinuric protein intolerance and hyperornithinemia-hyperammonemia-homocitrullinuria syndrome. Deficient activity of uridine-5'-monophosphate synthase produces orotic aciduria by preventing the conversion of orotic acid to orotidine-5'-monophosphate. WebLab tests show elevated orotic acid levels. Treatment with the following would most likely give the best improvement? Ribonucelotide reductase. A patient suffering from chronic myelogenous leukemia is treated with a selection of drugs that include hydroxyurea. Which of the following enzymes is directly inhibited by this drug?

Orotic acid is a Bronsted acid and its conjugate base, the orotate anion, is able bind to metals. Lithium orotate, for example, has been investigated for use in treating alcoholism, and complexes of cobalt, manganese, nickel, and zinc are known. The pentahydrate nickel orotate coordination complex converts into a … See more Orotic acid is a pyrimidinedione and a carboxylic acid. Historically, it was believed to be part of the vitamin B complex and was called vitamin B13, but it is now known that it is not a vitamin. The compound is … See more Dihydroorotate is synthesized to orotic acid by the enzyme dihydroorotate dehydrogenase, where it later combines with phosphoribosyl pyrophosphate (PRPP) to form orotidine-5'-monophosphate (OMP). A distinguishing characteristic of pyrimidine synthesis is … See more Orotic acid is a precursor to a DNA base (uracil), The Breast milk of smokers has a higher concentration of orotic acid than that of a non smoking woman.
