β-Nicotinamide adenine dinucleotide, txo daim ntawv, disodium ntsev (NADH ▪ 2ＮＡ)
NADH yog qhov txo qis coenzyme, nrog NAD (P)H ua qhov ntsuas qhov system thiab daim ntawv thov ntawm chromogen substrate hauv kev txiav txim siab ntawm kev ua haujlwm enzyme: muaj qhov nqus siab tshaj plaws ntawm 340nm, uas tuaj yeem kuaj xyuas cov ntsiab lus ntawm lactate dehydrogenase, thiaj li kuaj pom. kab mob ntxov.
NADH muab faib ua qib tshuaj ntsuam xyuas reagent, qib zaub mov noj qab haus huv.
Diagnostic reagent qib: Ua ke nrog ntau yam kev kuaj mob enzymes, raws li raw khoom ntawm cov khoom siv kuaj mob.
Kev noj qab haus huv qib: NADH cov khoom lag luam feem ntau yog muag hauv daim ntawv ntawm cov khoom noj khoom haus hauv European thiab Asmeskas kev lag luam.Muaj ntau lub npe ntawm NADH cov khoom lag luam nyob rau hauv kev ua lag luam, thiab cov txiaj ntsig kev tshaj tawm tsom rau kev tiv thaiv kev laus, pab cov neeg muaj circadianmoos tsis zoo los txo kev qaug zog, txhim kho lub hlwb, thiab txhim kho kev txawj ntse thiab lub cev ua haujlwm ntawm insomniacs;Tsis tas li ntawd, muaj cov tshuaj nplaum moisturizing, kho hniav gels, thiab lwm yam. Tsis txhob siv cov khoom.Txij li thawj cov khoom npaj ntawm NADH tau tsim tawm.xyoo 1996, nws tau txais los ntawm feem ntau ntawm cov neeg European thiab Asmeskas.Yog li ntawd, yuav luag txhua lub tuam txhab khoom noj khoom haus loj hauv Tebchaws Europe thiab Asmeskas tau tshaj tawm lawv tus kheej lub hom phiaj ntawm NADH npaj.
Peb ua lag luam kom zoo dua
① Biosynthesis, ntsuab thiab kev tiv thaiv ib puag ncig, raws li kev tiv thaiv ib puag ncig tam sim no hauv tsev thiab txawv teb chaws.
② Tus nqi qis thiab tus nqi sib tw.
③ Cov khoom ruaj khov, cov khoom lag luam mus sij hawm ntev.
