Cytosine was discovered by Albrecht Kossel in 1894 when it was hydrolysed from calf thymus tissues. However, it is inherently unstable, and can change into uracil (spontaneous deamination). In Watson-Crick base pairing, it forms three hydrogen bonds with guanine. COVID-19 is an emerging, rapidly evolving situation. Cytosine is one of the 5 main nucleobases used in storing and transporting genetic information within a cell in the nucleic acids DNA and RNA.. The difference being a deoxyribose and ribose sugar for respectively DNA and RNA. Cytosine (/ˈsaɪtəˌsiːn, -ˌziːn, -ˌsɪn/;[2][3] C) is one of the four main bases found in DNA and RNA, along with adenine, guanine, and thymine (uracil in RNA). In 1998, cytosine was used in an early demonstration of quantum information processing when Oxford University researchers implemented the Deutsch-Jozsa algorithm on a two qubit nuclear magnetic resonance quantum computer (NMRQC). 14631-20-0. In Watson-Crick base pairing, it forms three hydrogen bonds with guanine. Cytosine likely formed within some meteorite parent bodies, however did not persist within these bodies due to an effective deamination reaction into uracil. took place on August 1st in 1998 when researchers at Oxford implemented David Deutsch's algorithm on a two qubit NMRQC (Nuclear Magnetic Resonance Quantum Computer) based on the cytosine molecule.[2]. Cytarabine, also known as cytosine arabinoside (ara-C), is a chemotherapy medication used to treat acute myeloid leukemia (AML), acute lymphocytic leukemia (ALL), chronic myelogenous leukemia (CML), and non-Hodgkin's lymphoma.

It has a role as a human metabolite, an Escherichia coli metabolite, a Saccharomyces cerevisiae metabolite and a mouse metabolite. Cytosine: 4-aminopyrimidin-2(1H)-one (IUPAC Name), 4-amino-1H-pyrimidine-2-one (Other Name) The term, purine was coined by Emil Fischer, a German chemist, in 1884. ... 18% of the bases in a DNA molecule are cytosine. [10], InChI=1S/C4H5N3O/c5-3-1-2-6-4(8)7-3/h1-2H,(H3,5,6,7,8), InChI=1/C4H5N3O/c5-3-1-2-6-4(8)7-3/h1-2H,(H3,5,6,7,8), Except where otherwise noted, data are given for materials in their. Cytosine can also be methylated into 5-methylcytosine by an enzyme called DNA methyltransferase. Generating ... NMR Parameters. 4-amino-3H-pyrimidi n-2-one. mzCloud ‒ Free Online Mass Spectrometry Database Resources Search for: Cytosine arabinose . Print infocard Open Brief Profile. Cytosine can also be methylated into 5-methylcytosine by an enzyme called DNA methyltransferase or be methylated and hydroxylated to make 5-hydroxymethylcytosine. When cytosine is methylated, the DNA maintains the same sequence, but the expression of methylated genes can be altered (the study of this is part of the field of epigenetics). It is one of the four nucleobases in the nucleic acid of DNA that are represented by the letters G–C–A–T. Predicted data is generated using the US Environmental Protection Agency’s EPISuite™. 4-Amino-2 (1H)pyrimi done. The ‘Substance identity’ section is calculated from substance identification information from all ECHA databases. Pyrimidine 1 is the IUPAC accepted name for 1,3-diazabenzene, while quinazoline 2 is the accepted name for benzo[d] pyrimidine or 1,3-diazanaphthalene. What is the correct IUPAC name of the alkane illustrated below? When found third in a codon of RNA, cytosine is synonymous with uracil, as they are interchangeable as the third base. A correct name for the molecule shown below is 2,5-dimethylpentanal. La cystéine (Cys, C) est l’un des 22 acides aminés qui entrent dans la composition des protéines. The name cytosine (due to Kossel and Neumann) is misleading. Cytosine (/ˈsaɪtəˌsiːn, -ˌziːn, -ˌsɪn/; C) is one of the four main bases 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). nuclear magnetic resonance quantum computer (NMRQC), "Darstellung und Spaltungsprodukte der Nucleïnsäure (Adenylsäure)", "Weitere Untersuchungen über das Cytosin", "Implementation of a quantum algorithm on a nuclear magnetic resonance quantum computer", "NASA Ames Reproduces the Building Blocks of Life in Laboratory", "Discovery of bisulfite-mediated cytosine conversion to uracil, the key reaction for DNA methylation analysis — A personal account", "Prebiotic cytosine synthesis: a critical analysis and implications for the origin of life", 4'-O-β-D-Glucosyl-9-O-(6''-deoxysaccharosyl)olivil, https://en.wikipedia.org/w/index.php?title=Cytosine&oldid=995753008, Short description is different from Wikidata, Pages using collapsible list with both background and text-align in titlestyle, Articles containing unverified chemical infoboxes, Pages using multiple image with auto scaled images, Creative Commons Attribution-ShareAlike License, 320 to 325 °C (608 to 617 °F; 593 to 598 K) (decomposes), This page was last edited on 22 December 2020, at 18:32.
