Spermidine bụ polyamine dị mkpa nke dị n'ọtụtụ ihe dị ndụ ma na-esonye na usoro dị iche iche nke ndụ dịka mmụba nke mkpụrụ ndụ, nhazi na apoptosis. E nwere ọtụtụ ụdị usoro njikọta spermine: biosynthesis, njikọ kemịkalụ na njikọta enzymatic. Usoro ọ bụla nwere uru na ọghọm pụrụ iche nke ya na ọnọdụ ojiji.
Biosynthesis bụ ụzọ bụ isi e si emepụta spermine, nke a na-emekarị site na usoro mmeghachi omume enzymatic na mkpụrụ ndụ. Biosynthesis nke spermine dabere na metabolism nke amino acid, karịsịa lysine na arginine. Nke mbụ, a na-agbanwe lysine ka ọ bụrụ aminobutyric acid (Putrescine) site na lysine decarboxylase, wee jikọta aminobutyric acid na amino acid n'okpuru ọrụ nke spermine synthase iji mepụta spermine n'ikpeazụ. Na mgbakwunye, njikọta nke spermine gụnyekwara metabolism nke polyamines ndị ọzọ, dị ka putrescine (Cadaverine) na spermine (Spermine). Mgbanwe na mkpokọta nke polyamines ndị a na mkpụrụ ndụ ga-emetụta mmepụta nke spermine.
Usoro kemịkalụ bụ ụzọ a na-ejikarị eme ihe maka imepụta spermine n'ime ụlọ nyocha. A na-agbanwekarị ihe ndị dị mfe na organic ka ọ bụrụ spermine site na mmeghachi omume kemịkalụ. Ụzọ kemịkalụ ndị a na-ejikarị eme ihe na-amalite site na amino acid wee nweta spermine site na usoro mmeghachi omume esterification, mbelata na amination. Uru nke usoro a bụ na enwere ike ime ya n'okpuru ọnọdụ a na-achịkwa, ịdị ọcha ngwaahịa dị elu, ọ dịkwa mma maka obere nyocha ụlọ nyocha. Agbanyeghị, njikọta kemịkalụ na-achọkarị iji ihe mgbaze organic na ihe na-akpali akpali, nke nwere ike inwe mmetụta ụfọdụ na gburugburu ebe obibi.
Usoro mmepụta enzymatic bụ usoro mmepụta ọhụrụ nke emepụtara n'afọ ndị na-adịbeghị anya, nke na-eji mmeghachi omume enzyme-catalyzed kpọmkwem iji mepụta spermine. Uru nke usoro a bụ ọnọdụ mmeghachi omume dị nro, nhọrọ dị elu, na enyi gburugburu ebe obibi. Site na teknụzụ injinia mkpụrụ ndụ ihe nketa, enwere ike nweta spermine synthase dị irè, si otú a na-eme ka arụmọrụ mmepụta dịkwuo mma. Usoro mmepụta enzymatic nwere atụmanya ngwa ngwa sara mbara na mmepụta ụlọ ọrụ mmepụta ihe, karịsịa n'ọhịa nke biomedicine na ihe mgbakwunye nri.
Isi ihe dị na spermine bụ ngwakọta polyamine, gụnyere spermine, putrescine na triamine. Nhazi molekul nke spermine nwere ọtụtụ amino na imino otu, ma nwee ọrụ dị ike na bayoloji. Ọmụmụ ihe egosila na spermine na-arụ ọrụ dị mkpa na mmụba nke mkpụrụ ndụ, mgbochi oxidation, na mgbochi ịka nká. N'afọ ndị na-adịbeghị anya, ọtụtụ ọmụmụ achọpụtala na spermine nwekwara njikọ chiri anya na mmepe na mmepe nke ọrịa dị iche iche, dị ka kansa, ọrịa obi, na ọrịa neurodegenerative. Ya mere, njikọta na itinye spermine adọtala uche zuru ụwa ọnụ.
N'ọrụ bara uru, a pụrụ iji spermine ọ bụghị naanị dị ka ihe na-eme nchọpụta ihe ndị dị ndụ, kamakwa dị ka ihe mgbakwunye nri na ihe mejupụtara ngwaahịa ahụike. Ka ndị mmadụ na-elebara ahụike anya nke ọma, ọchịchọ ahịa maka spermine na-amụba nwayọ nwayọ. Site n'ịkwalite usoro mmepụta nke spermine, a pụrụ ịbawanye mmepụta na ịdị ọcha ya, a pụkwara ibelata ọnụ ahịa mmepụta, si otú a na-akwalite ojiji ya n'ọtụtụ ngalaba.
N'ozuzu, ụzọ mmepụta nke spermine gụnyere biosynthesis, kemịkalụ na njikọta enzymatic. Usoro ọ bụla nwere uru pụrụ iche ya na ọnọdụ ndị metụtara ya. Nnyocha n'ọdịnihu nwere ike ilekwasị anya n'imeziwanye arụmọrụ mmepụta, ibelata mmetụta gburugburu ebe obibi na ịgbasa ebe ojiji. Site na ọganihu na-aga n'ihu nke sayensị na teknụzụ, mmepụta na itinye spermine ga-eweta ohere mmepe ọhụrụ.
