Cov noob qesyog ib qho tseem ceeb ntawm cov tshuaj polyamine uas muaj ntau nyob rau hauv cov kab mob, tshwj xeeb tshaj yog ua lub luag haujlwm tseem ceeb hauv kev loj hlob thiab kev loj hlob ntawm cov cell. Spermine yog hloov pauv los ntawm cov amino acids arginine thiab ornithine. Tsab xov xwm no yuav tshawb nrhiav qhov chaw, kev ua haujlwm thiab qhov tseem ceeb ntawm spermine hauv cov kab mob.
Cov Khoom Siv ntawm Spermine
Qhov kev tsim cov spermine feem ntau nyob ntawm cov metabolism ntawm cov amino acids. Ua ntej, ornithine yog qhov ua ntej ntawm kev tsim cov spermine, uas tuaj yeem tsim los ntawm cov tshuaj decarboxylation ntawm arginine. Cov txheej txheem tshwj xeeb yog raws li nram no:
Arginine hloov pauv mus ua ornithine: Nyob rau hauv catalysis ntawm cov enzymes, arginine yog decarboxylated los tsim ornithine.
Kev Hloov Pauv ntawm ornithine mus rau spermine: Ornithine ntxiv mus ua ke nrog cov amino acid (feem ntau yog cov amino acid alanine) thiab, los ntawm ntau yam kev hloov pauv enzymatic, thaum kawg tsim cov spermine.
Cov txheej txheem hloov pauv no tsis yog tsuas yog cuam tshuam nrog cov metabolism ntawm cov amino acids xwb, tab sis kuj muaj feem cuam tshuam nrog kev loj hlob ntawm tes, kev faib thiab kev kho.
Cov teebmeem ntawm cov noob caj noob ces
Cov noob caj noob ces muaj ntau yam tseem ceeb hauv cov tsiaj txhu, feem ntau suav nrog cov hauv qab no:
Kev loj hlob ntawm cov cell thiab kev loj hlob: Cov phev ua lub luag haujlwm tseem ceeb hauv kev tswj hwm lub voj voog ntawm cov cell. Cov kev tshawb fawb tau qhia tias cov phev tuaj yeem txhawb nqa kev loj hlob ntawm cov cell, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem ntawm kev kho thiab rov ua dua cov ntaub so ntswg. Nws txhawb nqa kev faib cell thiab kev loj hlob los ntawm kev tswj hwm kev qhia tawm ntawm cov protein cuam tshuam nrog lub voj voog ntawm cov cell.
Cov nyhuv antioxidant: Spermine muaj cov khoom antioxidant, uas tuaj yeem tshem tawm cov free radicals hauv lub cev thiab txo qhov kev puas tsuaj rau cov hlwb los ntawm kev ntxhov siab oxidative. Cov khoom no ua rau spermine muaj txiaj ntsig zoo rau kev ncua kev laus thiab tiv thaiv cov kab mob ntsig txog hnub nyoog.
Kev Tswj Xyuas Kev Qhia Tawm ntawm Cov noob caj noob ces: Cov noob caj noob ces tuaj yeem tswj hwm kev qhia tawm ntawm cov noob caj noob ces los ntawm kev khi rau DNA thiab RNA. Qhov kev tswj hwm no yog qhov tseem ceeb rau kev ua haujlwm ntawm lub hlwb thiab lub xeev kev ua haujlwm ntawm lub cev, tshwj xeeb tshaj yog teb rau cov kev cuam tshuam sab nraud thiab kev ntxhov siab.
Txhawb nqa apoptosis: Hauv qee qhov xwm txheej, spermine kuj tseem tuaj yeem txhawb nqa apoptosis (programmed cell death), uas yog qhov tseem ceeb rau kev tswj hwm cellular homeostasis thiab kev noj qab haus huv ntawm cov ntaub so ntswg.
Kev tiv thaiv kab mob: Cov noob qes kuj tseem ua lub luag haujlwm tseem ceeb hauv lub cev tiv thaiv kab mob. Nws tuaj yeem txhim kho kev ua haujlwm ntawm cov hlwb tiv thaiv kab mob thiab txhim kho lub cev tiv thaiv kab mob thiab kab mob.
Spermine thiab Kev Noj Qab Haus Huv
Thaum kev tshawb fawb txog cov noob spermine tob zuj zus, ntau thiab ntau qhov pov thawj qhia tau tias cov noob spermine muaj feem cuam tshuam nrog ntau yam teeb meem kev noj qab haus huv. Piv txwv li, cov theem noob spermine muaj feem cuam tshuam nrog kev tshwm sim thiab kev loj hlob ntawm ntau yam kab mob xws li kev laus, kab mob plawv, thiab mob qog noj ntshav.
Kev Laus: Cov kev tshawb fawb tau pom tias cov theem spermine maj mam txo qis thaum lub sijhawm laus, thiab kev noj tshuaj spermine tuaj yeem pab qeeb qeeb cov txheej txheem laus thiab txhim kho kev noj qab haus huv ntawm cov neeg laus.
Kev Noj Qab Haus Huv ntawm Lub Plawv: Cov noob caj noob ces ua lub luag haujlwm tiv thaiv hauv lub plawv, txhim kho kev ua haujlwm ntawm endothelial thiab txo qhov kev pheej hmoo ntawm kab mob plawv.
xaus lus
Ua ib qho tseem ceeb ntawm cov tshuaj lom neeg, cov noob caj noob ces feem ntau yog los ntawm cov metabolism ntawm cov amino acids, tshwj xeeb tshaj yog kev hloov pauv ntawm arginine thiab ornithine. Cov noob caj noob ces ua lub luag haujlwm tseem ceeb hauv kev loj hlob ntawm tes, tiv thaiv kev oxidation, kev tswj hwm kev qhia tawm ntawm cov noob caj noob ces, thiab lwm yam, thiab yog qhov tseem ceeb rau kev tswj hwm kev noj qab haus huv thiab kev ua haujlwm ntawm cov kab mob. Nrog rau kev kawm tob txog cov noob caj noob ces, ntau cov ntaub ntawv hais txog nws lub luag haujlwm hauv kev noj qab haus huv thiab kab mob yuav raug tshawb pom yav tom ntej, muab cov tswv yim tshiab thiab cov txheej txheem rau kev tiv thaiv thiab kho cov kab mob cuam tshuam.
Los ntawm kev nkag siab txog keeb kwm thiab kev ua haujlwm ntawm cov noob caj noob ces (spermine), peb tuaj yeem nkag siab zoo dua txog nws qhov tseem ceeb hauv kev ua neej thiab muab lub hauv paus kev tshawb fawb rau kev txhawb nqa kev noj qab haus huv thiab ncua kev laus. Vam tias kev tshawb fawb yav tom ntej yuav qhia ntxiv txog kev siv cov noob caj noob ces thiab ua rau muaj kev pab ntau dua rau tib neeg kev noj qab haus huv.
