Cytosine |71-30-7
Tlhaloso ea Sehlahisoa
Cytosine ke e 'ngoe ea metheo e mene ea naetrojene e fumanoang ho nucleic acids, ho akarelletsa le DNA (deoxyribonucleic acid) le RNA (ribonucleic acid).
Sebopeho sa Lik'hemik'hale: Cytosine ke setsi sa pyrimidine se nang le lesale le le leng le nang le litho tse tšeletseng tse nkhang hamonate.E na le liathomo tse peli tsa nitrogen le liathomo tse tharo tsa carbon.Cytosine e atisa ho emeloa ke tlhaku "C" moelelong oa nucleic acids.
Karolo ea Likokoana-hloko
Nucleic Acid Base: Cytosine e etsa lipara tsa motheo le guanine ka hydrogen bonding ho DNA le RNA.Ho DNA, lipara tsa cytosine-guanine li kopantsoe hammoho ke libonto tse tharo tsa hydrogen, e leng se tlatsetsang botsitsong ba DNA double helix.
Liphatsa tsa lefutso Code: Cytosine, hammoho le adenine, guanine, le thymine (ka DNA) kapa uracil (ho RNA), e sebetsa e le e 'ngoe ea litšiea tsa ho haha khoutu ea lefutso.Tatellano ea metheo ea cytosine hammoho le li-nucleotide tse ling e na le boitsebiso ba liphatsa tsa lefutso 'me e lekanyetsa litšobotsi tsa lintho tse phelang.
Metabolism: Cytosine e ka etsoa de novo linthong tse phelang kapa ea fumanoa lijong ka ho ja lijo tse nang le nucleic acid.
Mehloli ea Lijo: Cytosine e fumanoa ka tlhaho lijong tse fapaneng, ho kenyelletsa nama, tlhapi, likhoho, lihlahisoa tsa lebese, linaoa le lijo-thollo.
Likopo tsa Phekolo: Cytosine le lihlahisoa tsa eona li 'nile tsa batlisisoa bakeng sa mekhoa ea phekolo e ka' nang ea e-ba teng libakeng tse kang phekolo ea kankere, phekolo ea likokoana-hloko, le mathata a metabolic.
Liphetoho tsa Lik'hemik'hale: Cytosine e ka ba le liphetoho tsa lik'hemik'hale, tse kang methylation, e nang le karolo ea ho laola liphatsa tsa lefutso, epigenetics le nts'etsopele ea maloetse.
