Solvolyses of cytosine and cytidine
Webcytosine sī´tōsēn˝ [ key], organic base of the pyrimidine family. It was isolated from the nucleic acid of calf thymus tissue in 1894. A suggested structure for cytosine, published in 1903, was confirmed in the same year when that base was synthesized in the laboratory. Combined with the sugar ribose in glycosidic linkage, cytosine forms a ... WebCytosine showed a pK 'a 2 assignable to a dissociation in highly alkaline solutions, and this anionic form appeared resistant to deamination. No such kinetic pK 'a 2 was assignable to …

The absorption spectra of triplet states of cytosine and cytosine derivatives have been observed for the first time.
WebCytidine triphosphate ( CTP) is a pyrimidine nucleoside triphosphate. CTP, much like ATP, consists of a ribose sugar, and three phosphate groups. The major difference between the two molecules is the base used, which in CTP is cytosine . CTP is a substrate in the synthesis of RNA. CTP is a high-energy molecule similar to ATP, but its role as an ... WebAs nouns the difference between cytarabine and cytidine. is that cytarabine is a particular drug used in chemotherapy while cytidine is (biochemistry genetics) a nucleoside consisting of cytosine linked to ribose.
