The nomenclature of pyrimidines is straightforward. However, like other heterocyclics, tautomeric hydroxyl groups yield complications since they exist primarily in the cyclic amide form. 65-86-1, formula is C5H4N2O4, Name is 2,6-Dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxylic acid. For example, 2-hydroxypyrimidine is more properly named 2-pyrimidone. A partial list of trivial names of various pyrimidines exists. Reference of 65-86-1.
Yi, Jing;Kaur, Harpreet;Kazone, Wahnyalo;Rauscher, Sophia A.;Gravillier, Louis-Albin;Muchowska, Kamila B.;Moran, Joseph research published 《 A Nonenzymatic Analog of Pyrimidine Nucleobase Biosynthesis》, the research content is summarized as follows. Metabolic theories for the origin of life posit that inorganic catalysts enabled self-organized chem. precursors to the pathways of metabolism, including those that make genetic mols. Recently, experiments showing nonenzymic versions of a number of core metabolic pathways have started to support this idea. However, exptl. demonstrations of nonenzymic reaction sequences along the de novo ribonucleotide biosynthesis pathways are limited. Here we show that all three reactions of pyrimidine nucleobase biosynthesis that convert aspartate to orotate proceed at 60 °C without photochem. under aqueous conditions in the presence of metals such as Cu2+ and Mn4+. Combining reactions into one-pot variants is also possible. Life may not have invented pyrimidine nucleobase biosynthesis from scratch, but simply refined existing nonenzymic reaction channels. This work is a first step towards uniting metabolic theories of life′s origin with those centered around genetic mols.
Reference of 65-86-1, Orotic acid anhydrous is a hydrogen bonding interaction that can be found in biological systems. It plays a role in the physiological effects of orotic acid, which is a metabolite of uridine and an intermediate in the synthesis of pyrimidine nucleotides. Orotic acid has antimicrobial properties and has been shown to inhibit enzyme activities involved in energy metabolism, such as polymerase chain reaction (PCR) and adenosine triphosphate (ATP) synthase. Orotic acid also inhibits the growth of bacteria, fungi, and parasites. Orotic acid anhydrous is used for treating myocardial infarcts or brain functions. The untreated group was given no treatment at all.
Orotic acid, also known as orotate or orotsaeure, belongs to the class of organic compounds known as pyrimidinecarboxylic acids. These are pyrimidines with a structure containing a carboxyl group attached to the pyrimidine ring. Orotic acid exists as a solid, slightly soluble (in water), and a moderately acidic compound (based on its pKa). Orotic acid has been found in human liver and pancreas tissues, and has also been primarily detected in saliva, feces, urine, and blood. Within the cell, orotic acid is primarily located in the cytoplasm and mitochondria. Orotic acid exists in all eukaryotes, ranging from yeast to humans. Orotic acid participates in a number of enzymatic reactions. In particular, Orotic acid can be biosynthesized from L-dihydroorotic acid and quinone; which is mediated by the enzyme dihydroorotate dehydrogenase (quinone), mitochondrial. In addition, Orotic acid and phosphoribosyl pyrophosphate can be converted into orotidylic acid through its interaction with the enzyme uridine monophosphate synthetase isoform a. In humans, orotic acid is involved in the pyrimidine metabolism pathway. Orotic acid is also involved in several metabolic disorders, some of which include the mngie (mitochondrial neurogastrointestinal encephalopathy) pathway, dihydropyrimidinase deficiency, UMP synthase deficiency (orotic aciduria), and Beta ureidopropionase deficiency. Outside of the human body, orotic acid can be found in a number of food items such as green vegetables, alaska blueberry, chickpea, and colorado pinyon. This makes orotic acid a potential biomarker for the consumption of these food products. Orotic acid is a potentially toxic compound. Orotic acid has been found to be associated with several diseases known as phosphoenolpyruvate carboxykinase deficiency 1, cytosolic and hyperornithinemia-hyperammonemia-homocitrullinuria; orotic acid has also been linked to several inborn metabolic disorders including n-acetylglutamate synthetase deficiency, lysinuric protein intolerance, and ornithine transcarbamylase deficiency.
Orotic acid appears as white crystals or crystalline powder.
Orotic acid is a pyrimidinemonocarboxylic acid that is uracil bearing a carboxy substituent at position C-6. It has a role as a metabolite, an Escherichia coli metabolite and a mouse metabolite. It derives from a uracil. It is a conjugate acid of an orotate., 65-86-1.
