Cytosine | 71-30-7
Incazelo Yomkhiqizo
I-Cytosine ingesinye sezisekelo ezine ze-nitrogen ezitholakala kuma-nucleic acid, okuhlanganisa i-DNA (deoxyribonucleic acid) ne-RNA (ribonucleic acid).
Isakhiwo Sekhemikhali: I-Cytosine isisekelo se-pyrimidine esinesakhiwo sendandatho enamalungu ayisithupha ephunga elimnandi. Iqukethe ama-athomu amabili e-nitrogen nama-athomu amathathu ekhabhoni. I-Cytosine ivame ukumelwa ngohlamvu "C" kumongo wama-nucleic acid.
Indima Yebhayoloji
I-Nucleic Acid Base: I-Cytosine yenza amapheya ayisisekelo ne-guanine ngokusebenzisa i-hydrogen bonding ku-DNA ne-RNA. Ku-DNA, amapheya e-cytosine-guanine abanjwe ndawonye ngamabhondi e-hydrogen amathathu, okunikela ekuzinzeni kwe-DNA double helix.
Ikhodi Yofuzo: I-Cytosine, kanye ne-adenine, i-guanine, ne-thymine (ku-DNA) noma i-uracil (ku-RNA), isebenza njengenye yezakhi zekhodi yofuzo. Ukulandelana kwezisekelo ze-cytosine kanye namanye ama-nucleotide athwala ukwaziswa kofuzo futhi kunquma izici zezinto eziphilayo.
I-Metabolism: I-Cytosine ingenziwa i-de novo ezintweni eziphilayo noma itholakale ekudleni ngokusebenzisa ukudla okuqukethe ama-nucleic acid.
Imithombo Yokudla: I-Cytosine itholakala ngokwemvelo ekudleni okuhlukahlukene, okuhlanganisa inyama, inhlanzi, izinkukhu, imikhiqizo yobisi, okusanhlamvu, okusanhlamvu.
Izicelo Zokwelapha: I-Cytosine kanye nokuphuma kwayo kuye kwaphenywa ukuze kusetshenziswe izindlela zokwelapha ezingase zibe khona ezindaweni ezifana nokwelashwa komdlavuza, ukwelashwa kwe-antiviral, kanye nokuphazamiseka kwe-metabolic.
Ukuguqulwa Kwamakhemikhali: I-Cytosine ingakwazi ukuguqulwa kwamakhemikhali, njenge-methylation, edlala indima ekulawuleni izakhi zofuzo, i-epigenetics, nokuthuthukiswa kwezifo.
