I-Spermidine yikhompawundi ye-polyamine yendalo efumaneka kwiintlobo ngeentlobo zokutya kwaye iveliswa ngumzimba. Ifumene ingqalelo ngenxa yeenzuzo zayo zempilo, ngakumbi ngokunxulumene nempilo yeseli, ubomi obude, kunye nokuguqulwa kwamandla.
I-Spermidine yi-polyamine compound edlala indima ebalulekileyo ekusebenzeni kweeseli kwaye ikhona kuzo zonke izinto eziphilayo.
Ifomyula yekhemikhali ye-spermidine yi-C7H22N3, kwaye isakhiwo sayo singachazwa njenge-polyamine enamasebe ebonakala ngokubakho kwamaqela amaninzi e-amine. Ngokukodwa, i-spermidine ifunyanwa kwenye i-polyamine, i-putrescine, ngokongeza iqela le-aminopropyl.
Ngokuphathelele ulwakhiwo lwemolekyuli, i-spermidine inomqolo oqulethwe ziintambo ezintathu zekhabhoni. Intambo yekhabhoni ephakathi ijikelezwe ngamaqela amabini e-amine, anoxanduva lweempawu zayo ezisisiseko. Iiathom ze-nitrogen kwi-spermidine zitshajwa kakuhle kwi-pH ye-physiological, nto leyo evumela i-molecule ukuba isebenzisane nezinto ezahlukeneyo zeseli, kuquka ii-nucleic acids kunye neeproteni. Olu nxibelelwano lubalulekile kwiinkqubo ezinje ngokukhula kweseli, ukwahlukana, kunye ne-apoptosis.
Ulwakhiwo lwe-spermidine lukwavumela ukuba ithathe inxaxheba ekulawuleni umsebenzi weseli ngokuthatha inxaxheba ekwenziweni kwezinye ii-biomolecules ezibalulekileyo. Umzekelo, sisiqalo se-spermine, enye i-polyamine enegalelo ngakumbi ekuzinzeni nasekusebenzeni kweseli.
Ukwenziwa kwe-spermidine
I-biosynthesis ye-spermidine yenzeka ngokuyintloko ngokusebenzisa i-decarboxylation ye-amino acid ornithine, ekhuthazwa yi-enzyme ornithine decarboxylase (ODC). Le mpendulo ivelisa i-putrescine, i-diamine esebenza njengomanduleli wokwenziwa kwe-spermidine. Inyathelo elilandelayo libandakanya ukongezwa kweqela le-aminopropyl kwi-putrescine, i-reaction eqhutywa yi-enzyme spermidine synthase. Le enzyme ikhuthaza ukudluliselwa kweqela le-aminopropyl ukusuka kwi-decarboxylated S-adenosylmethionine (dcSAM) ukuya kwi-putrescine, nto leyo ekhokelela ekudalweni kwe-spermidine.
Ukulawulwa kwe-spermidine biosynthesis kulawulwa ngokuqinileyo kumanqanaba amaninzi. Umsebenzi we-ODC uphantsi kokuthintelwa kwempendulo yi-polyamines ngokwazo, ukuqinisekisa ukuba amanqanaba eeseli zezi zinto zihlala ngaphakathi koluhlu lwe-physiological. Ukongeza, ukubonakaliswa kwe-ODC kulawulwa zizinto ezahlukeneyo, kubandakanya izinto zokukhula, iihomoni, kunye neempawu zoxinzelelo. Umzekelo, ngexesha lokwahlukana kweseli ngokukhawuleza okanye ukulungiswa kwezicubu, imfuno ye-spermidine iyanda, nto leyo ebangela ukunyuka kwe-ODC kunye nokuhlanganiswa kwe-polyamine okulandelayo.
I-Spermidine ayibalulekanga nje kuphela kwimisebenzi eqhelekileyo yeselula kodwa ikwabandakanyeka kwiingenelo ezahlukeneyo zempilo. Uphando lubonise ukuba i-spermidine inokukhuthaza i-autophagy, inkqubo yeselula esusa ii-organelles kunye neeproteni ezonakeleyo, ngaloo ndlela inegalelo ekuvuseleleni iiseli kunye nokuphila ixesha elide.
Ngaba i-spermidine iyasebenza ngokwenene
Uphando lubonise ukuba i-spermidine inokubangela i-autophagy, nto leyo enokunceda ukukhusela izifo ezinxulumene nokwaluphala. Uphononongo olupapashwe kwiphephancwadi elithi “Nature” lufumanise ukuba ukongezwa kwe-spermidine kwi-yeast, iimpukane, kunye neempuku kwandisa ubomi kwaye kuphucula iimpawu zempilo. Ezi ziphumo zibonisa ukuba i-spermidine inokuba nemiphumo efanayo ebantwini, nangona kufuneka uphando olongezelelweyo ukuqinisekisa oku.
Ukongeza kwiimpawu zayo zokulwa nokwaluphala, i-spermidine ifundwe ngeziphumo zayo ekusebenzeni kwengqondo. Ezinye izifundo zezilwanyana zibonise ukuba i-spermidine inokunceda ukukhusela izifo eziwohlokayo ze-neurodegenerative. Umzekelo, uphando olupapashwe kwi-"Cell Reports" lufumanise ukuba i-spermidine inokuphucula inkumbulo nokufunda kwiimpuku. Nangona ezi ziphumo zithembisa, kubalulekile ukuzijonga ngononophelo, njengoko izifundo zabantu zisencinci.
Ukuqukumbela, ngaba i-spermidine iyasebenza ngokwenene? Ubungqina bubonisa ukuba i-spermidine inako ukukhuthaza impilo yeseli, ixhase ukusebenza kwengqondo, kwaye inegalelo kwimpilo-ntle yentliziyo. Nangona kunjalo, uphando oluthe kratya luyafuneka ukuqonda ngokupheleleyo imiphumo yayo ebantwini kunye nokumisela amabango empilo aqinisekileyo. Njengakweyiphi na isongezelelo, kubalulekile ukusondela kwi-spermidine ngononophelo kwaye ubeke phambili ukutya okunesondlo kunye nendlela yokuphila enempilo ukuze ube sempilweni.
Iimpawu zokulwa nokwaluphala
Okuvuyisayo nge-spermidine yindima yayo ekunciphiseni ukuguga. Izifundo zibonise ukuba inokuqalisa inkqubo ebizwa ngokuba yi-autophagy. I-Autophagy inceda umzimba ukuba ukhuphe iindawo ezindala nezimbi.
Ngokwenza oku, i-spermidine ithintela izinto eziyingozi ekuqokeleleni kwiiseli. Oku kunokwenza iiseli zisebenze ngcono kwaye kuncede nokwandisa ubomi bazo.
Ukuqaliswa kwe-Autophagy
I-Autophagy yinkqubo ebalulekileyo "yokucoca" iiseli kunye nokuhlaziya umzimba. Ibalulekile kwimpilo yeeseli, kwaye xa iyancipha, umzimba wonke uchaphazeleka kakubi, nto leyo ebangela izifo ezinxulumene nokwaluphala kwaye inegalelo kwiimpawu zokwaluphala, ezifana nemigca emincinci kunye nemibimbi, iinwele ezingwevu, ibala elimnyama, impilo embi yamathumbu, nokunye.
Ngokuvuselela i-autophagy, i-spermidine inceda ekuvuseleleni iiseli, ukuqinisekisa ukuba zisebenza kwaye ziphinda zikhule ngokufanelekileyo. Olu hlaziyo lweeseli lubalulekile kwimpilo iyonke, njengoko amandla eeseli zethu echaphazela ngokuthe ngqo ukusebenza komzimba wethu wonke.
I-Spermidine ilungile kakhulu ekuqaliseni i-autophagy, nto leyo iindaba ezimnandi zokulwa nezifo ezibangelwa kukwaluphala. Ikwasusa iindawo ezimbi zeeseli kunye neeproteni. Oku kunokwenza iiseli zibe sempilweni kwaye kunciphise amathuba eengxaki ezinxulumene nokwaluphala.
Amandla anyukileyo kunye namandla
Ukongeza ekuphuculeni i-autophagy, i-spermidine ivuselela i-mitophagy - inkqubo esusa i-mitochondria endala nengasebenzi kakuhle. I-Mitochondria ziindawo zamandla zeeseli zethu, zibonelela ngamandla afunekayo kuyo yonke imisebenzi yeseli. Xa i-mitochondria ingasebenzi kakuhle, kuvela amanqanaba aphantsi amandla. Ngokukhuthaza ukuguquka kwe-mitochondria esempilweni, i-spermidine inceda ukubuyisela amandla kunye namandla, ngaloo ndlela ibuyisela ukunyamezela kunye namandla.
Iphucula impilo yengqondo, inkumbulo kunye nokuqonda
Ukwehla kwengqondo yingxaki eqhelekileyo yokwaluphala, kodwa i-spermidine inika ithemba kule ndawo. Ngokuvuselela i-autophagy, i-spermidine ixhasa impilo yengqondo kwaye iphucula ukusebenza kwengqondo. Uvavanyo lweklinikhi lwabantu lufumanise ukuba i-spermidine evela kwizityalo iphucula inkumbulo kunye nokuqonda kubantu abadala abanokuwohloka kwengqondo okubangelwa kukuqonda. Valelisa kwi-brain fog kwaye ubulise kwingcinga ecacileyo nebukhali.
