Cytosine | 71-30-7
Nkọwa ngwaahịa
Cytosine bụ otu n'ime ntọala nitrogen anọ dị na acid nucleic, gụnyere DNA (deoxyribonucleic acid) na RNA (ribonucleic acid).
Nhazi kemịkalụ: Cytosine bụ ntọala pyrimidine nwere otu mgbanaka aromatic nwere otu isii. O nwere atom nitrogen abụọ na carbon carbon atọ. Cytosine na-anọchi anya mkpụrụedemede "C" n'ihe gbasara acid nucleic.
Ọrụ ndu
Nucleic Acid Base: Cytosine na-etolite isi ụzọ abụọ na guanine site na njikọ hydrogen na DNA na RNA. Na DNA, a na-ejikọta ụzọ abụọ cytosine-guanine site na njikọ hydrogen atọ, na-enye aka na nkwụsi ike nke helix abụọ DNA.
Usoro mkpụrụ ndụ ihe nketa: Cytosine, yana adenine, guanine, na thymine (na DNA) ma ọ bụ uracil (na RNA), na-eje ozi dị ka otu n'ime ihe mgbochi nke koodu mkpụrụ ndụ ihe nketa. Usoro nke ntọala cytosine yana nucleotides ndị ọzọ na-ebu ozi mkpụrụ ndụ ihe nketa na-ekpebi njirimara nke ihe ndị dị ndụ.
Metabolism: Cytosine nwere ike synthesized de novo na ntule ma ọ bụ nweta nri site na oriri nke nwere nucleic acid.
Isi mmalite nri: A na-ahụ Cytosine na nri dị iche iche, gụnyere anụ, azụ, anụ ọkụkọ, ngwaahịa mmiri ara ehi, mkpo, na ọka.
Ngwa ọgwụgwọ: enyochala Cytosine na ihe ndị sitere na ya maka ngwa ọgwụgwọ nwere ike na mpaghara dị ka ọgwụgwọ ọrịa kansa, ọgwụ mgbochi nje na ọrịa metabolic.
Mgbanwe kemịkalụ: Cytosine nwere ike ime mgbanwe kemịkalụ, dị ka methylation, nke na-ekere òkè na nhazi mkpụrụ ndụ ihe nketa, epigenetics, na mmepe nke ọrịa.
