FLASH PHOTOLYSIS STUDIES OF OROTIC ACID

Photochemistry and Photobiology, 1971
Abstract— The triplet state of orotic acid has been studied by flash photolysis. The rate for dimerization has been observed to vary from 2 × 109M‐1 sec‐1 at pH 1 where both the triplet and ground state molecules are neutral, to under 108 M‐1 sec‐1 above pH 9 where both the triplet and ground state molecules are doubly ionized.

Mechanism of Cardioprotective Effect of Orotic Acid

Cardiovascular Drugs and Therapy, 1998
The pyrimidine base, orotic acid (OA), markedly improves the function of recently infarcted hearts subjected to global ischemia. The mechanism of cardiac action of OA is unclear, but it has been proposed that OA acts by correcting a relative deficiency of nucleotide precursors required for RNA synthesis in the stressed myocardium or by improving ...

Microbiological decarboxylation of orotic acid to uracil

Folia Microbiologica, 1965
У различных микробов была обнаружена способность декарбоксилировать оротовую кислоту в урацил. С применением избранного штамма E. coli в 0,08% растворе оротовой кислоты образовалось свыше 60% теоретического количества урацила. При выделении с помощью анионита было получено около 45% теоретического количества урацила в кристаллической форме.

Orotic acid content of infant formulas

The American Journal of Clinical Nutrition, 1980
The orotic acid content of four commercially available infant formulas has been examined. Enfamil contains 118 microgram orotic acid per milliliter as fed, Similac 98, SMA 27, and Isomil less than 1 microgram/ml. As expressed relative to total solids, these formulas contain less than 0.1% orotic acid.

Metabolic supplementation with orotic acid and magnesium orotate.

Cardiovascular drugs and therapy, 1999
Orotic acid (OA), a naturally occurring substance, is a key intermediate in the biosynthetic pathway of pyrimidines. Previous investigations in the heart suggest that orotate can protect recently infarcted hearts against a further ischemic stress and may be beneficial in certain types of experimental cardiomyopathy.
