WebA variety of hydrazone-linked functionalities are readily added under mild conditions, including cationic, anionic, electron-rich/poor, and hetereoatom-containing aromatics. Owing to its rapid functionalization and simple and scalable synthesis, this material is an accommodating and generalized polymer scaffold that is rapidly tailored to a variety of … Cytosine (symbol C or Cyt) is one of the four nucleobases found in DNA and RNA, along with adenine, guanine, and thymine (uracil in RNA). It is a pyrimidine derivative, with a heterocyclic aromatic ring and two substituents attached (an amine group at position 4 and a keto group at position 2). The nucleoside of … See more Cytosine was discovered and named by Albrecht Kossel and Albert Neumann in 1894 when it was hydrolyzed from calf thymus tissues. A structure was proposed in 1903, and was synthesized (and thus confirmed) in the … See more When found third in a codon of RNA, cytosine is synonymous with uracil, as they are interchangeable as the third base.
