Spermidine yog ib qho tshuaj polyamine uas muaj nyob hauv ntau yam khoom noj thiab lub cev tsim tawm. Nws tau txais kev saib xyuas rau nws cov txiaj ntsig kev noj qab haus huv, tshwj xeeb tshaj yog hais txog kev noj qab haus huv ntawm tes, lub neej ntev, thiab kev ua kom lub zog metabolism.
Spermidine yog ib qho tshuaj polyamine uas ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm tes thiab muaj nyob rau hauv txhua yam tsiaj txhu.
Cov mis tshuaj ntawm spermidine yog C7H22N3, thiab nws cov qauv tuaj yeem piav qhia tias yog ib qho branched polyamine uas muaj ntau pawg amine. Tshwj xeeb, spermidine yog muab los ntawm lwm cov polyamine, putrescine, los ntawm kev ntxiv ib pawg aminopropyl.
Hais txog cov qauv molecular, spermidine muaj ib lub pob txha caj qaum uas muaj peb txoj saw hlau carbon. Lub hauv paus carbon saw hlau yog ob pawg amine nyob ib sab, uas yog lub luag haujlwm rau nws cov khoom tseem ceeb. Cov nitrogen atoms hauv spermidine muaj cov nqi zoo ntawm physiological pH, uas ua rau lub molecule sib cuam tshuam nrog ntau yam khoom ntawm lub cellular, suav nrog nucleic acids thiab proteins. Qhov kev sib cuam tshuam no yog qhov tseem ceeb rau cov txheej txheem xws li kev loj hlob ntawm lub cell, kev sib txawv, thiab apoptosis.
Cov qauv ntawm spermidine kuj tso cai rau nws koom nrog kev tswj hwm kev ua haujlwm ntawm tes los ntawm kev koom nrog kev tsim cov biomolecules tseem ceeb. Piv txwv li, nws yog ib qho ua ntej ntawm spermine, lwm yam polyamine uas ntxiv rau kev ruaj khov thiab kev ua haujlwm ntawm tes.
Biosynthesis ntawm spermidine
Qhov biosynthesis ntawm spermidine feem ntau tshwm sim los ntawm decarboxylation ntawm cov amino acid ornithine, uas yog catalyzed los ntawm enzyme ornithine decarboxylase (ODC). Qhov tshuaj tiv thaiv no tsim putrescine, ib qho diamine uas ua haujlwm ua ntej rau kev tsim cov spermidine. Kauj ruam tom ntej yog ntxiv ib pawg aminopropyl rau hauv putrescine, ib qho tshuaj tiv thaiv uas enzyme spermidine synthase pab txhawb. Qhov enzyme no catalyzes kev hloov pauv ntawm ib pawg aminopropyl los ntawm decarboxylated S-adenosylmethionine (dcSAM) mus rau putrescine, ua rau muaj kev tsim cov spermidine.
Kev tswj hwm ntawm spermidine biosynthesis raug tswj hwm nruj ntawm ntau theem. Cov haujlwm ntawm ODC raug kev cuam tshuam los ntawm polyamines lawv tus kheej, ua kom ntseeg tau tias cov theem cellular ntawm cov tshuaj no tseem nyob hauv qhov ntau ntawm lub cev. Tsis tas li ntawd, kev qhia tawm ntawm ODC raug tswj hwm los ntawm ntau yam, suav nrog cov yam ntxwv kev loj hlob, cov tshuaj hormones, thiab cov cim kev ntxhov siab. Piv txwv li, thaum lub sijhawm ntawm kev faib cell sai lossis kho cov ntaub so ntswg, qhov kev thov rau spermidine nce ntxiv, ua rau muaj kev nce ntxiv ntawm ODC thiab tom qab ntawd polyamine synthesis.
Spermidine tsis yog tsuas yog tseem ceeb rau kev ua haujlwm ntawm lub hlwb xwb tab sis kuj tau koom nrog ntau yam txiaj ntsig kev noj qab haus huv. Kev tshawb fawb tau qhia tias spermidine tuaj yeem txhawb autophagy, ib qho txheej txheem ntawm lub hlwb uas tshem tawm cov organelles thiab cov protein uas puas tsuaj, yog li ua rau lub hlwb rov qab zoo thiab ua neej ntev.
Puas yog spermidine ua haujlwm tiag tiag
Kev tshawb fawb tau qhia tias spermidine tuaj yeem ua rau autophagy, uas yuav pab tiv thaiv cov kab mob ntsig txog hnub nyoog. Ib txoj kev tshawb fawb luam tawm hauv phau ntawv xov xwm "Nature" pom tias kev ntxiv spermidine rau hauv cov poov xab, yoov, thiab nas ua rau lub neej ntev dua thiab txhim kho cov cim kev noj qab haus huv. Cov kev tshawb pom no qhia tias spermidine yuav muaj cov teebmeem zoo sib xws rau tib neeg, txawm hais tias xav tau kev tshawb fawb ntxiv los lees paub qhov no.
Ntxiv rau nws cov peev xwm tiv thaiv kev laus, spermidine tau raug kawm txog nws cov teebmeem rau kev ua haujlwm ntawm lub hlwb. Qee qhov kev tshawb fawb hauv tsiaj tau qhia tias spermidine yuav pab tiv thaiv cov kab mob neurodegenerative,. Piv txwv li, kev tshawb fawb luam tawm hauv "Cell Reports" pom tias spermidine tuaj yeem txhim kho kev nco thiab kev kawm hauv nas. Txawm hais tias cov txiaj ntsig no muaj kev cia siab, nws yog qhov tseem ceeb uas yuav tsum tau ua tib zoo saib xyuas lawv, vim tias kev tshawb fawb tib neeg tseem muaj tsawg.
Xaus lus, puas yog spermidine ua haujlwm tiag? Cov pov thawj qhia tias spermidine muaj peev xwm txhawb kev noj qab haus huv ntawm lub hlwb, txhawb kev ua haujlwm ntawm lub hlwb, thiab pab txhawb kev noj qab haus huv ntawm lub plawv thiab cov hlab ntsha. Txawm li cas los xij, yuav tsum muaj kev tshawb fawb ntxiv kom nkag siab txog nws cov teebmeem rau tib neeg thiab los tsim kom muaj kev lees paub txog kev noj qab haus huv. Ib yam li lwm yam tshuaj ntxiv, nws yog ib qho tseem ceeb uas yuav tsum siv spermidine nrog kev ceev faj thiab muab qhov tseem ceeb rau kev noj zaub mov kom sib npaug thiab kev ua neej noj qab haus huv kom muaj kev noj qab haus huv zoo tshaj plaws.
Cov khoom tiv thaiv kev laus
Qhov zoo siab txog spermidine yog nws lub luag haujlwm hauv kev qeeb qeeb kev laus. Kev tshawb fawb tau qhia tias nws tuaj yeem pib ua ib qho txheej txheem hu ua autophagy. Autophagy pab lub cev tshem tawm cov khoom qub thiab tsis zoo.
Ua li no, spermidine tiv thaiv cov tshuaj lom kom tsis txhob sib sau ua ke hauv cov cell. Qhov no yuav ua rau cov cell ua haujlwm zoo dua thiab pab kom ntev lub neej.
Kev ua kom lub cev tsis muaj zog (autophagy induction)
Autophagy yog ib qho tseem ceeb ntawm cov hlwb "ntxuav" thiab rov ua dua tshiab hauv lub cev. Nws yog qhov tseem ceeb rau kev noj qab haus huv ntawm cov hlwb, thiab thaum nws qeeb zuj zus, tag nrho lub cev raug cuam tshuam tsis zoo, ua rau cov kab mob ntsig txog hnub nyoog hnyav dua thiab ua rau muaj cov cim qhia txog kev laus, xws li cov kab zoo thiab cov pob khaus, cov plaub hau dawb, cov tawv nqaij tsis zoo, kev noj qab haus huv ntawm txoj hnyuv tsis zoo, thiab ntau ntxiv.
Los ntawm kev txhawb nqa autophagy, spermidine pab ua kom cov hlwb rov qab zoo, xyuas kom lawv ua haujlwm thiab rov tsim dua tshiab. Qhov kev tsim kho tshiab ntawm cov hlwb no yog qhov tseem ceeb rau kev noj qab haus huv tag nrho, vim tias lub zog ntawm peb cov hlwb cuam tshuam ncaj qha rau kev ua haujlwm ntawm peb lub cev tag nrho.
Spermidine zoo heev rau kev pib autophagy, uas yog xov xwm zoo rau kev tawm tsam cov kab mob uas los nrog kev laus. Nws kuj tshem tawm cov hlwb tsis zoo thiab cov protein. Qhov no yuav ua rau cov hlwb noj qab haus huv zoo dua thiab txo qhov muaj feem yuav muaj teeb meem ntsig txog kev laus.
Muaj zog thiab lub zog ntxiv
Ntxiv rau qhov ua kom autophagy zoo dua, spermidine ua kom mitophagy ua haujlwm - ib qho txheej txheem uas tshem tawm cov mitochondria qub thiab tsis ua haujlwm zoo. Mitochondria yog lub zog ntawm peb cov hlwb, muab lub zog xav tau rau txhua yam haujlwm ntawm lub hlwb. Thaum mitochondria tsis ua haujlwm zoo, cov qib zog qis tshwm sim. Los ntawm kev txhawb nqa kev hloov pauv ntawm cov mitochondria noj qab haus huv, spermidine pab rov qab muaj zog thiab muaj zog, yog li rov qab muaj zog thiab muaj zog.
Txhim kho kev noj qab haus huv ntawm lub hlwb, kev nco qab thiab kev paub
Kev poob qis ntawm kev xav yog ib qho teeb meem uas tshwm sim thaum laus, tab sis spermidine kuj muaj kev cia siab rau qhov no thiab. Los ntawm kev txhawb nqa autophagy, spermidine txhawb nqa kev noj qab haus huv ntawm lub hlwb thiab txhim kho kev ua haujlwm ntawm kev xav. Ib qho kev sim tshuaj hauv tib neeg pom tias spermidine los ntawm cov nroj tsuag tau txhim kho kev nco thiab kev paub hauv cov neeg laus uas muaj kev poob qis ntawm kev xav. Hais lus zoo rau lub hlwb tsis meej thiab nyob zoo rau kev xav meej dua thiab ntse dua.
Suzhou Myland Nutraceuticals Inc. yog ib lub tuam txhab uas tsom mus rau kev tshawb fawb thiab kev txhim kho thiab kev tsim cov khoom siv raw khoom noj khoom haus, thiab cog lus tias yuav muab cov neeg siv khoom nrog Spermidine uas muaj qhov huv siab.
