Shi, Qianqian;Han, Gang;Liu, Yu;Jiang, Junjun;Jia, Yuyao;Li, Xingang research published 《 Nutrient composition and quality traits of dried jujube fruits in seven producing areas based on metabolomics analysis》, the research content is summarized as follows. Chinese jujube is a widely cultivated fruit of the Rhamnaceae family. However, there are few reports on the comprehensive evaluation of jujube fruit quality in the main jujube producing areas. Liquid chromatog. tandem-mass spectrometry (LC-MS/MS), principal component anal. (PCA), cluster anal., and ranking score were used to comprehensively evaluate the metabolic traits and quality of 20 dried jujube varieties in the seven main producing areas in China. A total of 29 categories of 463 metabolites were identified and detected; among them, alkaloids, amino acids, flavonoids, and lipids are the main nutrients in dried jujube fruits. An anal. of the content of metabolites in dried jujube fruits from seven producing areas showed that the difference in the fruit quality traits between the producing areas is significant, exhibiting the regional characteristics of the eastern and western regions in North China. In addition, jujube varieties HN-L-L (72 points), XJ-H-Hm (59 points), and XJ-H-Hp (59 points) with the highest scores are rich in nutrients and can be used as raw materials in the development of functional foods.
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., HPLC of Formula: 65-86-1
