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