Nicotinamide mononucleotide, tseem hu ua NMN, tau tshwm sim los ua ib qho kev txaus siab zoo vim nws lub luag haujlwm tseem ceeb hauv cellular metabolism thiab cov txiaj ntsig kev noj qab haus huv. Tab sis yuav ua li cas yog qhov tseem ceeb compound tsim? Tsab ntawv xov xwm no yuav muab kev saib xyuas qhov tob ntawm biosynthetic thiab tshuaj synthesis txoj hauv kev rau tsim NMN.
Nicotinamide mononucleotide, los yog NMN, yog ib tug subordinate ntawm vitamin B3 uas tau txais kev tshawb fawb tseem ceeb tsis ntev los no. Raws li ib tug forerunner rau nicotinamide adenine dinucleotide (NAD +), NMN yog ib qho tseem ceeb rau kev tsim lub zog, DNA kho, thiab lwm yam indispensable cell muaj peev xwm. Txhim kho nrog NMN tau tshwm sim los pab NAD + qib thiab tuaj yeem muab cov txiaj ntsig tiv thaiv kev laus. Ua li ntawd, peb lub cev tsuas yog tsim cov kev txwv ntawm NMN ib txwm. Kev nkag siab txog yuav ua li cas NMN biosynthesized nyob rau hauv cov xwm thiab tuaj yeem ua hluavtaws orchestrated hauv chav kuaj muab cov kev paub tseem ceeb hauv kev daws nws cov peev xwm kho dua tshiab.
Nicotinamide Mononucleotide (NMN) yog dab tsi?
Nicotinamide mononucleotide yog nucleotide muab los ntawm ribose thiab nicotinamide. Nws cov qauv tshuaj muaj xws li phosphate pawg, ribose qab zib, thiab nicotinamide moiety. NMN tau pom tias yog tus tseem ceeb NAD + precursor, txhais tau tias nws yuav tsum tau hloov tam sim ntawd rau NAD + los ntawm cov lus teb enzymatic. NAD + yog ib qho tseem ceeb coenzyme cuam tshuam nrog kev ua pa ntawm tes thiab lub zog zom zaub mov.
Kev tshawb fawb qhia tau hais tias NMN supplementation nyob rau hauv nas tuaj yeem nce NAD + ntau ntau thiab sirtuin kev ua si, replicating cov teebmeem ntawm calorie txwv. Qhov no tau ua rau muaj kev txaus siab tseem ceeb hauv NMN ua tus neeg sib tw tiv thaiv kev laus. Tib neeg kev sim siab tseem muaj tsawg tab sis qhia kom txhawb nqa NMN tuaj yeem muab cov txiaj ntsig neuroprotective thiab mob plawv los ntawm kev txhim kho NAD + xwm txheej. Raws li ib tug natural NAD + precursor, nkag siab li casNMNhmoovyog synthesized muab kev nkag siab rau optimizing nws bioproduction.
Puas yog NMN Synthetic lossis Natural?
Nicotinamide mononucleotide feem ntau pom muaj nyob hauv txhua lub cell nyob, qhov twg nws suav tias yog ib feem tseem ceeb hauv NAD + txoj hauv kev biosynthesis. Txawm li cas los xij, tus nqi ntawm NMN uas tuaj yeem tau los ntawm cov khoom noj muaj tsawg heev. Economically xa NMN yog synthetically orchestrated nyob rau hauv labs siv nyob rau hauv kev tshawb fawb kev tshawb fawb thiab kev txhim kho.

Biosynthesis ntawm Nicotinamide Mononucleotide
Hauv cov kab ke lom neeg, NMN yog tsim los ntawm txoj hauv kev sib txawv enzymatic raws li qhov tshwj xeeb ntawm NAD + metabolism. Nov yog ib feem ntawm txoj kev tseem ceeb:
- Los ntawm nicotinamide los ntawm nicotinamide phosphoribosyltransferase (NAMPT): NAMPT catalyzes pauv phospholipase los ntawm phosphoribosyl pyrophosphate (PRPP) mus rau nicotinamide, shaping NMN. Qhov no yog qhov txwv tsis pub txav mus rau NAD + sib xyaw.
- Los ntawm nicotinic acid mononucleotide (NaMN) los ntawm nicotinamide mononucleotide adenylyltransferase (NMNAT): NaMN hloov tag nrho rau NMN siv NMNAT, uas txav ib pawg adenylyl los ntawm ATP.
- Los ntawm nicotinamide riboside (NR) los ntawm nicotinamide riboside kinases (NRKs): Phosphorylation ntawm NR los ntawm NRK compounds tsim NMN. NR tuaj yeem tau los ntawm kev noj zaub mov noj lossis hloov ntawm NAD +.
- Los ntawm tryptophan ntawm txoj kev de novo: Tryptophan tawg mus rau hauv NAMN, uas tom qab ntawd hloov mus rau NMN los ntawm NMNAT enzymes.
Cov kev no tso cai rau cov hlwb kom tswj tauNMNthiab NAD + qib txawm tias lub sijhawm muaj kev xav tau metabolic siab lossis DNA puas. Lub siab yog tshwj xeeb tshaj yog nplua nuj nyob rau hauv NAMPT thiab NMN biosynthesis kev ua.
Tshuaj Synthesis ntawm Nicotinamide Mononucleotide
Thaum lub hlwb tuaj yeem tsim NMN ib txwm muaj, cov tshuaj synthesis yog tsim nyog los tsim kom muaj qhov xav tau rau kev tshawb fawb, tshuaj, thiab tshuaj ntxiv. Muaj ntau ntau txoj hauv kev NMN tuaj yeem ua tshuaj lom neeg hauv chav kuaj:
- Los ntawm nicotinamide thiab phosphoribosyl pyrophosphate nyob rau hauv alkaline tej yam kev mob. Qhov no tsom rau txoj kev biosynthetic siv NAMPT enzymes thiab koom nrog cov tshuaj tiv thaiv condensation ntawm nicotinamide thiab PRPP.
- Siv phosphoramidite chemistry, ribose phosphate reacts nrog nicotinamide los tsim phosphoramidite intermediate uas cyclizes rau NMN thaum rhuab.
- Phosphorylation ntawm nicotinamide riboside (NR) siv phosphate pub nyiam phosphoric acid. NR ua tus thawj coj tsis yog nicotinamide.
- Enzymatic synthesis siv NRK enzymes thiab ATP rau phosphorylate NR. Qhov no ua raws txoj kev biosynthetic los ntawm NR mus rau NMN.
- Siv engineered E. coli kab mob rau overexpress NRK thiab NAMPT enzymes rau microbial ntau lawm. Cov enzymes catalyze NMN synthesis hauv cov hlwb.
Cov tswv yim tshuaj lom neeg thiab enzymatic tso cai rau NMN los ua cov khoom loj ntawm purities thiab ntau tshaj qhov uas yuav muab rho tawm los ntawm tej yam ntuj tso.
