Payvasthoi geterosikli

Payvasthoi geterosikli, geterosiklho, payvasthoi organikii sokhti sikli (se, chor, panjkunja va az in hm ziyod) doshtae, ki dar tarkibashon gayr az atomhoi karbon boz atomhoi digar elementho geteroatomho va gayra dorand.

Payvasthoi geterosikliro bo miqdori atomhoi sikl (halqa), khususiyat, adad va joi geteroatom, budan yo nabudani joynishin, khususiyati aromati doshtan va digar khosiyathoyashon az hamdigar farq me­kunand. Khosiyati khimiyavii yak diski Payvasthoi  geterosikli, az qabili furan, tiofen, pir­rol, piridin, khinolin va gayra ba payvasthoi aromati qarobat dorand. Chunin moddaho az hisobi jufti ya- elektronhoi geteroatomashon bo metallho payvasti kompleksi hosil menamoyand. Masalan, payvasti khinolin- bie-benzoatn So (II)

Payvasthoi geterosikli, ki geteroatomashon nitroge­nu okengen ast, dar shakli alkaloid, vitamin va pigmentho vase pahn shuda, dar prosesshoi muhimi bio­logii organizmhoi zinda roli ka­lon mebozand. Khlorofilli nabotot, gemini khun, baze aminokislotaho, penisillin, kofein az jumlai Payvasthoi geterosikliand. Piridin, khinolin, akridinro az tarkibi zifti angishtsang va furfurolro az oftobparast ba dast meorand. Qismi ziyodi P.ayvasthoi geterosiklii tabiiyu sinteziro ba sifati rang (indi­go) va doruvor (khinin, morfin, ak­rikhin, analgin, amidopirin va gayra) istifoda mebarand. Payvasthoi geterosikli inchunin dar digar sohahoi sanoat, monan- di istehsoli plastmassaho, sanoati kino, suratgiri va gayra ba kor meravand.
