Yeyiphi i-amino acid eguqulwa yi-spermine? Yintoni umsebenzi wayo?

I-Spermineyi-polyamine compound ebalulekileyo efumaneka kakhulu kwizinto eziphilayo, ingakumbi edlala indima ephambili ekwandeni nasekukhuleni kweeseli. I-Spermine iguqulwa kwi-amino acids i-arginine kunye ne-ornithine. Eli nqaku liza kuhlola umthombo, umsebenzi kunye nokubaluleka kwe-spermine kwizinto eziphilayo.

Imithombo yeSpermine

Ukwenziwa kwe-spermine kuxhomekeke kakhulu kwi-metabolism ye-amino acids. Okokuqala, i-ornithine yindlela yokwenziwa kwe-spermine, enokuthi iveliswe yi-decarboxylation reaction ye-arginine. Inkqubo ethile yile ilandelayo:

I-Arginine iguqulwa ibe yi-ornithine: Phantsi kwe-catalysis yee-enzymes, i-arginine iyasuswa kwi-carboxylated ukuze ivelise i-ornithine.
Ukuguqulwa kwe-ornithine ibe yi-spermine: I-Ornithine idibaniswa ngakumbi ne-amino acid (ngesiqhelo yi-amino acid alanine) kwaye, ngothotho lwee-enzyme reactions, ekugqibeleni yenza i-spermine.
Le nkqubo yokuguqula ayibandakanyi kuphela imetabolism yee-amino acids, kodwa ikwanxulumene ngokusondeleyo nokukhula kweeseli, ukwahlukana kunye nokulungiswa.

Iziphumo zebhayoloji zesidoda

I-Spermine inemisebenzi emininzi ebalulekileyo yebhayoloji kwizinto eziphilayo, ingakumbi ezi zinto zilandelayo:

Ukwanda nokukhula kweeseli: I-spermine idlala indima ebalulekileyo ekulawuleni umjikelo weseli. Izifundo zibonise ukuba i-spermine inokukhuthaza ukwanda kweeseli, ingakumbi kwinkqubo yokulungiswa nokuvuselelwa kwezicubu. Ikhuthaza ukwahlukana nokukhula kweeseli ngokulawula ukubonakaliswa kweeproteni ezinxulumene nomjikelo weseli.

Isiphumo se-Antioxidant: I-Spermine ineempawu ze-antioxidant, ezinokususa ii-free radicals emzimbeni kwaye zinciphise umonakalo kwiiseli ezibangelwa luxinzelelo lwe-oxidative. Le propati yenza i-spermine ibe nexabiso elinokwenzeka lokusetyenziswa ekulibaziseni ukuguga nasekuthinteleni izifo ezinxulumene nokuguga.

Ukulawula ukubonakaliswa kwezakhi zofuzo: I-Spermine inokulawula ukubonakaliswa kwezakhi zofuzo ngokuzibophelela kwi-DNA kunye ne-RNA. Esi siphumo sokulawula sibalulekile ekusebenzeni kweseli kunye nesimo somzimba, ingakumbi xa kuphendulwa izinto zangaphandle kunye noxinzelelo.

Ikhuthaza i-apoptosis: Phantsi kweemeko ezithile, i-spermine inokukhuthaza i-apoptosis (ukufa kweeseli okucwangcisiweyo), nto leyo ebalulekileyo ekugcineni i-homeostasis yeeseli kunye nempilo yezicubu.

Ukuguqulwa kwamasosha omzimba: I-Spermine ikwadlala indima ebalulekileyo kwinkqubo yomzimba yokuzikhusela. Ingaphucula ukusebenza kweeseli zomzimba kwaye iphucule ukumelana komzimba nosulelo nezifo.

I-Spermine kunye neMpilo

Njengoko uphando nge-spermine luqhubeka lusanda, ubungqina obuninzi bubonisa ukuba i-spermine inxulumene kakhulu neengxaki ezahlukeneyo zempilo. Umzekelo, amanqanaba e-spermine anxulumene kakhulu nokwenzeka kunye nophuhliso lwezifo ezahlukeneyo ezifana nokwaluphala, isifo sentliziyo kunye nomhlaza.

Ukwaluphala: Izifundo zifumanise ukuba amanqanaba e-spermine ayancipha kancinci kancinci ngexesha lokwaluphala, kwaye ukongezwa kwe-spermine kunokunceda ukucothisa inkqubo yokwaluphala nokuphucula impilo yabantu abadala.

Impilo yeNtliziyo neMithambo: I-Spermine idlala indima yokukhusela kwinkqubo yentliziyo, iphucula ukusebenza kwe-endothelial kwaye inciphisa umngcipheko wesifo sentliziyo.

ukuququmbela

Njengemolekyuli ebalulekileyo yebhayoloji, i-spermine ifumaneka kakhulu kwi-metabolism yee-amino acids, ingakumbi ukuguqulwa kwe-arginine kunye ne-ornithine. I-spermine idlala indima ebalulekileyo ekwandeni kweeseli, ekulweni ne-oxidation, ekulawuleni ukubonakaliswa kwezakhi zofuzo, njl.njl., kwaye ibalulekile ekugcineni impilo kunye nokusebenza kwezinto eziphilayo. Ngophando olunzulu lwe-spermine, ulwazi oluthe kratya malunga nendima yayo kwimpilo nakwizifo lunokufunyanwa kwixesha elizayo, lubonelele ngeengcinga ezintsha kunye neendlela zokuthintela kunye nokunyanga izifo ezinxulumene noko.

Ngokuqonda imvelaphi kunye nomsebenzi we-spermine, sinokuqonda ngcono ukubaluleka kwayo kwimisebenzi yobomi kwaye sinike isiseko sesayensi sokukhuthaza impilo kunye nokulibazisa ukuguga. Kuthenjwa ukuba uphando lwexesha elizayo luya kutyhila ngakumbi ukusetyenziswa kwe-spermine kwaye lube negalelo elikhulu kwimpilo yabantu.
