描述 | Orotic acid, also known as 6-Carboxyuracil, serves as a precursor in the biosynthesis of pyrimidine nucleotides and RNA. It is released from mitochondrial dihydroorotate dehydrogenase (DHODH) and converted to UMP by the cytoplasmic UMP synthase enzyme. Orotic acid is utilized as a biomarker in routine newborn screening for urea cycle disorders and can induce hepatic steatosis and hepatomegaly in rats[1][2][3]. |
体内研究 | Orotic acid serves as a biomarker for diagnosing urea cycle disorders (UCDs), including ornithine transcarbamylase deficiency (OTCD)[2]. A dietary addition of 1.0% orotic acid, administered orally for 3-10 days, precipitates the onset of fatty liver by the seventh day and reduces the purine/pyrimidine ratio of hepatic acid-soluble nucleotides by the third day[3]. |
体外研究 | Present in milk and dairy products, orotic acid is predominantly converted into uridine within the liver, kidneys, and erythrocytes, facilitating the pyrimidine salvage pathway[2]. |
