Genetic Analysis of Orotic Acid Predicted With Fourier Transform Infrared Milk Spectra [PDF]

Journal of Dairy Science, 2020
Fourier transform infrared spectral analysis is a cheap and fast method to predict milk composition. A not very well studied milk component is orotic acid.

Orotate (orotic acid): An essential and versatile molecule

Nucleosides, Nucleotides & Nucleic Acids, 2016
Orotate (OA) is well-known as a precursor in biosynthesis of pyrimidines; in mammals it is released from the mitochondrial dihydroorotate dehydrogenase (DHODH) for conversion to UMP by the cytoplasmic UMP synthase enzyme. OA is also a normal part of the diet, being found in milk and dairy products, and it is converted to uridine for use in the ...

Determination of orotic acid in urine

Journal of Chromatography B: Biomedical Sciences and Applications, 1994
Orotic acid was separated from other urinary constituents by ion-pair formation with tetrabutylammonium, and isocratic elution from a reversed-phase column. Absorbance at 280 nm was recorded for quantitation. Owing to the better column characteristics the separations are somewhat faster, and the sensitivity of the method is higher than those of ...

Triplet state of orotic acid and orotic acid methyl ester in solution

Canadian Journal of Chemistry, 1970
Flash photolysis of orotic acid and orotic acid methyl ester in aqueous solution was studied. The transients were identified as triplet excited states on the basis of their lifetimes, sensitization, quenching, and self-quenching experiments. The rate constants for self-quenching and for decay of the triplet were measured and discussed in terms of ...

Orotic Acid in Urine and Hyperammonemia

1982
Orotoc acid (OA) an intermediary metabolite of the pyrimidine synthesis pathway is formed from carbamylphosphate (CP) and aspartate (Fig. 1). In the liver these precursors are synthetised mainly in the mitochondrium1,2,3 . Natale and Tremblay4 showed that CP formed by carbamylphosphate synthetase (CPS I) in the mitochondria crosses the mitochondrial ...

Urinary Orotic Acid Excretion in Hyperammonaemic Sheep; II. Renal Clearance of Orotic Acid

Journal of Veterinary Medicine Series A, 1988
SummaryThe renal orotate clearance (Corotate) in control (infusion of 0.9% NaCl into jugular vein) and hyperammonaemic (infusion of NH4Cl in a dose of 20 μmol · kg−1· min−1) conditions in the same sheep was investigated. Corotate was compared with Cinulin, a valid index of glomerular filtration rate (GFR).

Vibrational analysis and spectra of orotic acid

Biopolymers, 1999
The IR and Raman spectra of polycrystalline anhydrous orotic acid and its N1, N3, and O12 trideuterated isotopomer are recorded in the 4000-40 cm(-1) spectral interval as part of a series of vibrational analyses of nucleosides, nucleotides, and related compounds carried out in our laboratory.

Metabolic Effect of Orotic Acid in Calves*

Journal of Veterinary Medicine Series A, 1993
SummaryEight calves (males, Black and White crossbred with Holstein‐Fresian) were fed milk and milk replacer without (control group) or with potassium orotate (3 mmol./l.) supplementation for 6 weeks after birth.Orotate depressed the biosynthesis of polyamines in mucosa of the gastrointestinal tract (rumen, omasum, abomasum, colon) by decreasing of ...
