β-Nicotinamide adenine dinucleotide, mawonekedwe ochepetsedwa, mchere wa disodium (NADH ▪ 2ＮＡ)
NADH ndi coenzyme yocheperako, yokhala ndi NAD(P)H ngati njira yodziwira ndi kugwiritsa ntchito gawo la chromogen pozindikira ntchito ya enzyme: pali chiwopsezo cha kuyamwa pa 340nm, chomwe chingathe kuzindikira kuchuluka kwa lactate dehydrogenase, kuti tizindikire matenda msanga.
NADH imagawidwa m'magulu a reagent diagnostic, kalasi ya chakudya chathanzi.
Gulu la reagent yodziwira matenda: Yophatikizidwa ndi ma enzyme osiyanasiyana odziwira matenda, monga zinthu zopangira zida zodziwira matenda.
Zakudya zabwino: Zogulitsa za NADH zimagulitsidwa kwambiri ngati zowonjezera zakudya m'misika ya ku Europe ndi America. Pali mitundu yambiri ya zogulitsa za NADH pamsika, ndipo zotsatira zake zotsatsira zimayang'ana kwambiri pakulimbana ndi ukalamba, kuthandiza anthu omwe ali ndi vuto la circadian.Matenda a wotchi kuti achepetse kutopa, kusintha maganizo, ndikuwonjezera luso la kuzindikira ndi kugwira ntchito kwa thupi kwa anthu omwe ali ndi vuto la kusowa tulo; kuphatikiza apo, pali mafuta odzola, ma gels a mano, ndi zina zotero. Musagwiritse ntchito mankhwala. Kuyambira pomwe mankhwala oyamba okonzekera a NADH adayambitsidwa.Mu 1996, anthu ambiri aku Europe ndi America adavomereza izi. Chifukwa chake, pafupifupi makampani onse akuluakulu azakudya ku Europe ndi America ayambitsa mtundu wawo wodziyimira pawokha wa NADH.
Ubwino wathu pamsika
① Biosynthesis, chitetezo chobiriwira komanso cha chilengedwe, mogwirizana ndi zofunikira pakali pano zoteteza chilengedwe m'dziko ndi kunja.
② Mtengo wotsika komanso mtengo wopikisana.
③ Kupezeka kokhazikika, kupezeka kwa masheya kwa nthawi yayitali.

NADH ndi mtundu wa coenzyme yochepetsedwa. Kugwiritsa ntchito NAD(P)H ngati njira yowonetsera ndi gawo la chromogen pozindikira ntchito ya enzyme: pali chiwopsezo cha kuyamwa pa 340nm, chomwe chingathe kuzindikira kuchuluka kwa lactate dehydrogenase, kuti tipeze matenda msanga. Kugwiritsa ntchito NADH kumaphatikizapo kalasi ya reagent yozindikira matenda ndi kalasi ya chakudya chathanzi.
