When Oxford University researchers introduced the Deutsch-Jozsa algorithm on a two-qubit nuclear magnetic resonance quantum computer in 1998, cytosine was used in an early demonstration of quantum information processing (NMRQC). Cytosine likely formed within some meteorite parent bodies, however did not persist within these bodies due to an effective deamination reaction into uracil. Enrolling in a course lets you earn progress by passing quizzes and exams. OMP decarboxylase is an enzyme that aids in the decarboxylation of OMP to produce uridine monophosphate (UMP). Cytosine undergoes deamination to uracil. IUPAC name or chemical name of cytosine is 4-aminopyridine-2(1H)-one. Cytosine deamination appears to be largely responsible for spontaneous mutations in the modern world. Cytosine bonds with guanine in both DNA and RNA. Structure As a nitrogenous base, cytosine is full of nitrogen atoms (it has three). Cytosine has other roles in the cell, too, as the energy carrier and cofactor CTP. Deamination, for example, can transform cytosine to uracil. In Watson-Crick base pairing, it forms three hydrogen bonds with guanine. For example, if we want to obtain the Lewis structure of the Sulfate ion, SO4- 2, we must first enter the charge by typing (-2) or by entering -2 in . Each strand has a backbone made of alternating sugar (deoxyribose) and . For example, cytidine analogues have been examined for their usefulness in antiviral mechanisms, chemotherapeutics, and antidepressants. nuclear magnetic resonance quantum computer (NMRQC), "Darstellung und Spaltungsprodukte der Nuclensure (Adenylsure)", "Weitere Untersuchungen ber 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", "Identifying the wide diversity of extraterrestrial purine and pyrimidine nucleobases in carbonaceous meteorites", "Prebiotic cytosine synthesis: a critical analysis and implications for the origin of life", 4'-O--D-Glucosyl-9-O-(6''-deoxysaccharosyl)olivil, https://en.wikipedia.org/w/index.php?title=Cytosine&oldid=1103385777, 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 3.0, 320 to 325C (608 to 617F; 593 to 598K) (decomposes), This page was last edited on 9 August 2022, at 12:40.

A substituent is an atom or group of atoms that is substituted for a hydrogen atom on the parent chain of a hydrocarbon in organic chemistry. Lewis structures, also known as electron-dot or electron-dot diagrams, are diagrams showing the bonding between a molecule's atoms and the lone pairs of electrons that may occur in the molecule. | Function, Importance & Uses. Structure of Cytosine [Click Here for Sample Questions] The structure of cytidine is made of ribonucleic acid which contains cytosine and sugar ribose. (Hint: Complete Lewis structure with lone pairsas necessary). Purines in DNA strands will be so large if they are bound to each other instead of the pyrimidines that the pyrimidines will be unable to enter other pyrimidines or purines on the other hand! Berg, Jeremy M. John L. Tymoczko. This methylation has two functions: It suppresses the migration of transposons. succeed. The heterocyclic ring of cytosine contains an amine group at position 4 and a keto group at position 2. Cytosine binds with ribose to form the nucleoside cytidine and with deoxyribose to form deoxycytidine. This website collects cookies to deliver a better user experience.

When the pyrimidine nucleotide cytidine monophosphate (CMP) or cytosine is catabolized, the by-products -alanine, ammonia, and carbon dioxide are created. Cytosine Structure Cytosine is an aminopyrimidine with the amino group at position 4 and is pyrimidin-2-one. The 3D chemical structure image of cytosine is based on the ball-and-stick model which displays both the three-dimensional position of the atoms and the bonds between them. It is a base because the nitrogen atoms can donate their lone pair of electrons and form covalent bonds. Outside of nucleic acids, cytosine is part of CTP, an energy carrier and cofactor that can help enzymes do their jobs. They perform essential functions in inheritance, metabolism, and other cellular functions. Cytosine is a pyrimidine that binds with its purine counterpart, guanine.

For example, in base excision repair the uracil is cleaved and removed by uracil glycosylase from the DNA. It bonds with adenine in DNA. Since DNA does not contain uracil, so the uracil formed due to the deamination of cytosine is identified as foreign and is removed by a repair system. cytosine, a nitrogenous base derived from pyrimidine that occurs in nucleic acids, the heredity-controlling components of all living cells, and in some coenzymes, substances that act in conjunction with enzymes in chemical reactions in the body. For example, cytidine analogues have shown promise in enhancing the efficacy of antidepressants and by serving as potent agents in epigenetics via their ability to demethylate cytosine and adenine.

Cytosine is one of the five primary (or canonical) nucleobases. It is a pyrimidine derivative which has one heterocyclic aromatic carbon ring structure. An enzyme called DNA methyltransferase can also methylate cytosine into 5-methylcytosine. If DNA repair enzymes such as uracil glycosylase do not repair the damage by cleaving uracil in DNA, a point mutation may result. On phosphorylation with 3 phosphoric acid groups they yield dCTP and CTP nucleotides that play a role in the building of nucleic acids like DNA and RNA. The fact that DNA encodes all of its information in four bases, each with its own letter, allows us to write the DNA code by just representing the letters.
