Spermidine ndi polyamine yofunika kwambiri yomwe imapezeka kwambiri m'zamoyo ndipo imagwira ntchito zosiyanasiyana zamoyo monga kuchulukana kwa maselo, kusiyanitsa ndi apoptosis. Pali mitundu ingapo ya njira zopangira umuna: biosynthesis, chemical synthesis ndi enzymatic synthesis. Njira iliyonse ili ndi ubwino wake wapadera ndi zovuta zake komanso zochitika zogwiritsidwa ntchito.
Kupanga kwa spermine ndiyo njira yayikulu yopangira spermine, yomwe nthawi zambiri imachitika kudzera mu ma enzyme reaction angapo m'maselo. Kupanga kwa spermine kumadalira kwambiri kagayidwe ka amino acid, makamaka lysine ndi arginine. Choyamba, lysine imasinthidwa kukhala aminobutyric acid (Putrescine) ndi lysine decarboxylase, kenako aminobutyric acid imasakanikirana ndi amino acids pansi pa mphamvu ya spermine synthase kuti pamapeto pake ipange spermine. Kuphatikiza apo, kupanga kwa spermine kumaphatikizaponso kagayidwe ka polyamines zina, monga putrescine (Cadaverine) ndi spermine (Spermine). Kusintha kwa kuchuluka kwa polyamines izi m'maselo kudzakhudza kapangidwe ka spermine.
Kupanga mankhwala ndi njira yomwe imagwiritsidwa ntchito kwambiri popanga umuna mu labotale. Mankhwala osavuta achilengedwe nthawi zambiri amasinthidwa kukhala umuna kudzera mu zochita za mankhwala. Njira zodziwika bwino zopangira mankhwala zimayambira pa ma amino acid ndipo pamapeto pake zimapeza umuna kudzera mu zochitika zingapo zoyezera, kuchepetsa ndi kusuntha. Ubwino wa njira iyi ndikuti imatha kuchitika pansi pa mikhalidwe yolamulidwa, kuyera kwa chinthucho kumakhala kwakukulu, ndipo ndikoyenera kafukufuku wa labotale yaying'ono. Komabe, kupanga mankhwala nthawi zambiri kumafuna kugwiritsa ntchito zosungunulira zachilengedwe ndi zoyambitsa, zomwe zingakhale ndi zotsatira zina pa chilengedwe.
Kupanga ma enzyme ndi njira yatsopano yopangira ma enzyme yomwe idapangidwa m'zaka zaposachedwa, yomwe imagwiritsa ntchito njira yapadera yopangira ma enzyme kuti ipange umuna. Ubwino wa njira iyi ndi momwe zinthu zimachitikira pang'onopang'ono, kusankha bwino, komanso kusamala chilengedwe. Kudzera muukadaulo wa majini, kupanga ma spermine synthase kogwira mtima kungapezeke, motero kumawonjezera magwiridwe antchito a kupanga. Kupanga ma enzyme kuli ndi mwayi waukulu wogwiritsidwa ntchito popanga mafakitale, makamaka m'magawo a biomedicine ndi zakudya zowonjezera.
Zigawo zazikulu za umuna ndi mankhwala a polyamine, kuphatikizapo umuna, putrescine ndi triamine. Kapangidwe ka molekyulu ka umuna uli ndi magulu angapo a amino ndi imino, ndipo uli ndi mphamvu yamphamvu ya zamoyo. Kafukufuku wasonyeza kuti umuna umagwira ntchito yofunika kwambiri pakuchulukana kwa maselo, kuletsa okosijeni, komanso kuletsa ukalamba. M'zaka zaposachedwapa, kafukufuku wochulukirachulukira wapeza kuti umuna umagwirizananso kwambiri ndi kupezeka ndi kukula kwa matenda osiyanasiyana, monga khansa, matenda a mtima, ndi matenda owononga mitsempha. Chifukwa chake, kupanga ndi kugwiritsa ntchito umuna kwakopa chidwi cha anthu ambiri.
Mu ntchito zenizeni, umuna ungagwiritsidwe ntchito osati ngati chothandizira pa kafukufuku wa zamoyo zokha, komanso ngati chowonjezera pazakudya komanso chopangira thanzi. Pamene anthu akusamala kwambiri za thanzi, kufunikira kwa umuna pamsika kukuwonjezeka pang'onopang'ono. Mwa kukonza njira yopangira umuna, phindu lake ndi chiyero chake zitha kuwonjezeredwa, ndipo mtengo wopangira ukhoza kuchepetsedwa, potero kulimbikitsa kugwiritsidwa ntchito kwake m'magawo osiyanasiyana.
Kawirikawiri, njira zopangira umuna zimaphatikizapo kupanga zinthu zatsopano, kupanga mankhwala ndi kupanga ma enzyme. Njira iliyonse ili ndi ubwino wake wapadera komanso zochitika zoyenera. Kafukufuku wamtsogolo angayang'ane kwambiri pakukweza magwiridwe antchito opangira, kuchepetsa kuwononga chilengedwe komanso kukulitsa madera ogwiritsira ntchito. Ndi kupita patsogolo kosalekeza kwa sayansi ndi ukadaulo, kupanga ndi kugwiritsa ntchito umuna kudzabweretsa mwayi watsopano wokukula.
Chodzikanira: Nkhaniyi ndi yongofuna kudziwa zambiri ndipo siyenera kuonedwa ngati upangiri uliwonse wa zachipatala. Zina mwa zomwe zili mu blog iyi zimachokera pa intaneti ndipo si zaukadaulo. Webusaitiyi ili ndi udindo wosankha, kupanga ndi kusintha nkhani zokha. Cholinga chopereka zambiri sichikutanthauza kuti mukugwirizana ndi malingaliro ake kapena kutsimikizira kuti zomwe zili mkati mwake ndi zoona. Nthawi zonse funsani katswiri wa zaumoyo musanagwiritse ntchito zowonjezera zilizonse kapena kusintha njira yanu yazaumoyo.
