Beschreibung
Cytidine is a pyrimidine nucleoside that is composed of the pyrimidine base cytosine attached to the sugar ribose. As a constituent of RNA, cytidine pairs with guanine, and it is a precursor of uridine. Cytidine can incur several modifications in mRNA, including methylation and acetylation, that function to regulate translation. Cytidine can also be formylated to 5-formylcytidine in mitochondrial methionine transfer RNA (tRNAMet).
Chemische Eigenschaften
Cytidine is a component of RNA. It is a white water-soluble solid. which is only slightly soluble in ethanol.There are a variety of cytidine analogs with potentially useful pharmacology.
Verwenden
Cytidine is a nucleoside molecule that is formed when cytosine is attached to a ribose ring, cytidine is a component of RNA. It was isolated from yeast nucleic acid. It can increases cell membrane phospholipids. Cytidine is used to synthesize enzyme inhibitors, antiviral agents, and anticancer agents. And also used as constituent of nucleic acids.
Application
Cytidine has been used as a non-essential aminoacid component of minimal essential medium (MEM) to analyse interspecies somatic cell nucleus transfer (iSCNT)-derived blastocysts. It has also been used as a supplement in the culture medium of HeLa cells, to study the effects of cytidine addition on rods and rings (RR) induced by glutamine deprivation.
Cytidine has been used as a component to prepare ribonucleoside stock solution to assess its effects on the anaerobic growth of several Bacillus mojavensis strains.
Definition
ChEBI: cytidine is a pyrimidine nucleoside in which cytosine is attached to ribofuranose via a beta-N(1)-glycosidic bond. It has a role as a human metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite. It derives from a cytosine.The derivednucleotides, cytidine mono-, di-, andtriphosphate (CMP, CDP, and CTP respectively)participate in various biochemicalreactions, notably inphospholipid synthesis.
Allgemeine Beschreibung
White crystalline powder.
Air & Water Reaktionen
Cytidine is hygroscopic. Water soluble.
Reaktivität anzeigen
Cytidine is incompatible with strong oxidizing agents. . Will react as a weak base.
Brandgefahr
Flash point data for Cytidine are not available; however, Cytidine is probably combustible.
läuterung methode
Cytidine crystallises from 90% aqueous EtOH. It has also been converted to sulfate by dissolving (~200mg) in a solution of EtOH (10mL) containing H2SO4 (50mg), whereby the salt crystallises out. It is collected, washed with EtOH and dried for 5hours at 120o/0.1mm. The sulfate has m 225o. The free base is obtained by shaking the salt solution with a weak ion-exchange resin, filtering, evaporating and recrystallising the residue from EtOH as before.
