Nicotinamide adenine dinucleotide(NAD) tau dhau los ua ib qho ntawm cov khoom xyaw sib tham tshaj plaws hauv ntiaj teb kev noj qab haus huv, nutraceutical, thiab kev lag luam tshuaj. Nws txuas nrog lub zog metabolism, kho cellular, noj qab nyob zoo laus, thiab mitochondrial muaj nuj nqi. Raws li kev lag luam kev txaus siab loj hlob, cov lus nug tsis tu ncua thiab tseem ceeb tshwm sim: Puas yog NAD yog cov khoom siv los yog cov khoom lag luam? Qhov no tsis yog tsuas yog ib lo lus nug txog kev tshawb fawb tab sis kuj yog kev lag luam thiab cov tswv yim. Puas yog NAD Substrate lossis Khoom?
Dab tsi yog"Substrate" thiab "Cov khoom"?
Nws yog ib qho tseem ceeb ua ntej kom meej meej ob lub ntsiab lus siv dav hauv biochemistry thiab industrial biotechnology: substrate thiab khoom. Cov ntsiab lus no piav qhia txog yuav ua li cas cov molecules koom nrog hauv enzyme-tsav cov tshuaj tiv thaiv, uas tsim lub hauv paus ntawm cov txheej txheem metabolic thiab ntau yam kev lag luam.
Ib substrate
Lub substrate yog cov molecule uas ib qho enzyme ua rau. Nws tuaj yeem nkag siab tias yog "cov tswv yim" ntawm cov tshuaj tiv thaiv biochemical. Thaum cov tshuaj tiv thaiv pib, cov enzyme khi rau nws cov substrate thiab pab txhawb kev hloov pauv tshuaj. Feem ntau, lub substrate yog hloov, noj, los yog hloov dua siab tshiab thaum lub sij hawm tus txheej txheem. Los ntawm kev xav txog kev lag luam, substrates feem ntau suav hais tias yog cov khoom siv raw, vim tias lawv muaj, tus nqi, thiab kev ruaj ntseg ncaj qha cuam tshuam rau kev tsim khoom thiab kev ua kom muaj zog.
Ib yam khoom
Ntawm qhov tod tes, ib yam khoom yog cov molecule lossis molecules generated los ntawm cov tshuaj tiv thaiv enzymatic. Cov khoom lag luam sawv cev rau "tso zis" ntawm cov txheej txheem thiab feem ntau tso tawm thaum cov tshuaj tiv thaiv tiav. Hauv ob qho tib si lom neeg thiab kev tsim khoom lag luam, cov khoom lag luam yog lub hom phiaj sib txuas uas xa cov txiaj ntsig zoo, xws li kev tsim hluav taws xob, kev ua haujlwm, lossis cov txiaj ntsig kev noj haus.
Thaum ib qho enzyme catalyzes cov tshuaj tiv thaiv, substrates tau hloov mus rau hauv cov khoom los ntawm cov txheej txheem tswj tau zoo thiab muaj txiaj ntsig. Qhov kev hloov pauv no yog lub hauv paus rau cov metabolism, fermentation, thiab biocatalysis. Kev nkag siab seb cov khoom sib txuas ua haujlwm li cas los yog cov khoom lag luam yog qhov tseem ceeb vim nws txiav txim siab seb cov khoom sib xyaw li cas tau noj, rov tsim dua tshiab, lossis sib sau ua ke hauv lub cev.
Nyob rau hauv rooj plaub ntawm NAD, cov lus txhais no tseem ceeb tshwj xeeb. NAD tuaj yeem ua raws li cov neeg koom nrog cov tshuaj tiv thaiv uas tau hloov pauv ib ntus thiab rov tsim dua tshiab, tsis yog siv tas mus li. Qhov kev coj cwj pwm ob no muaj qhov cuam tshuam tseem ceeb tsis yog rau kev nkag siab txog kev lom neeg nkaus xwb tab sis kuj yog rau yuav ua li cas NAD yog tsim, tsim, ua lag luam, thiab siv rau hauv cov khoom noj, khoom noj khoom haus, tshuaj, thiab biotechnology industries.
Puas yog NAD substrate?
Los ntawm kev xav txog kev siv biochemical, NAD tuaj yeem piav qhia raws li lub substrate hauv ntau cov tshuaj tiv thaiv enzymatic, tshwj xeeb yog cov txheej txheem oxidation-txo (redox).

NAD Lub Luag Haujlwm hauv Redox Reactions
Hauv cov hlwb uas muaj sia nyob, kev tsim hluav taws xob yog nyob ntawm kev tswj kev hloov pauv ntawm electrons. NAD muaj nyob rau hauv ob daim ntawv sib hloov:
• NAD⁺ (Oxidized daim ntawv)
• NADH (txo daim ntawv)
Thaum lub sij hawm metabolic tshua, NAD⁺ lees txais electrons (feem ntau nyob rau hauv daim ntawv ntawm hydride ion) los ntawm lwm cov molecules, ua NADH. Hauv kev tshwm sim tom ntej, NADH pub cov khoom siv hluav taws xob thiab hloov mus rau NAD⁺. Lub voj voog txuas ntxiv no yog qhov tseem ceeb rau cov txheej txheem xws li glycolysis, lub voj voog tricarboxylic acid (TCA), thiab oxidative phosphorylation.
Vim tias NAD ncaj qha koom nrog cov kev cuam tshuam no thiab tshwm sim ntawm sab reactant ntawm cov tshuaj sib npaug, nws yog technically raug los piav txog NAD raws li substrate hauv cov tshuaj tiv thaiv enzymatic.
NAD ua lub substrate hauv Enzyme-Catalyzed Reactions
Hauv biochemistry, lub substrate yog ib qho molecule uas ib qho enzyme ua rau. Hauv ntau qhov kev cuam tshuam dehydrogenase, NAD⁺ kom meej meej raws li cov ntsiab lus no.
Piv txwv li:
• Glycerol-3-phosphate dehydrogenase siv NAD⁺ ua substrate ua ke nrog glycerol-3-phosphate. Hauv cov tshuaj tiv thaiv no, NAD⁺ lees txais electrons thiab raug txo rau NADH, thaum glycerol-3-phosphate hloov mus rau hauv dihydroxyacetone phosphate.
• Aldehyde dehydrogenase siv NAD⁺ ua substrate los oxidize aldehydes rau hauv lawv cov kua qaub. Thaum lub sij hawm tus txheej txheem no, NAD⁺ raug txo rau NADH, ua kom detoxification thiab metabolic processing ntawm aldehydes.
Nyob rau hauv ob qho tib si, NAD⁺ yuav tsum tau ua ib qho kev tawm tswv yim molecule rau cov tshuaj tiv thaiv mus ntxiv. Yog tsis muaj nws, enzyme tsis tuaj yeem ua nws txoj haujlwm catalytic. Qhov no yog vim li cas NAD feem ntau tau teev nyob rau ntawm "substrate side" ntawm kev sib npaug ntawm cov tshuaj tiv thaiv.
Coenzyme Substrate: Lub Sij Hawm Ntau Yam
Txawm hais tias NAD ua haujlwm raws li lub substrate hauv ib tus neeg cov tshuaj tiv thaiv, nws txawv ntawm cov substrates xws li qab zib lossis amino acids. Cov txheej txheem substrates yog tshuaj hloov pauv thiab nws thiaj li tawg los yog muab tso rau hauv lwm cov molecules. NAD, ntawm qhov sib txawv, tsis noj. Hloov chaw, nws ua raws li coenzyme substrate, txhais tau tias nws koom ncaj qha rau hauv cov tshuaj tiv thaiv tab sis yog rov tsim dua thiab rov siv dua thoob plaws ntau lub voj voog.
