β-Nicotinamide adenine dinucleotide, ụdị mbelata, nnu disodium (NADH ▪ 2ＮＡ)
NADH bụ coenzyme e belatara, ya na NAD(P)H dị ka usoro ihe ngosi na itinye ihe chromogen substrate n'ịchọpụta ọrụ enzyme: enwere oke mmịpụta na 340nm, nke nwere ike ịchọpụta ọdịnaya nke lactate dehydrogenase, iji chọpụta ọrịa n'oge.
A na-ekewa NADH n'ime ọkwa ihe mgbaàmà nke ọrịa, ọkwa nri ahụike.
Ọkwa ihe nchọpụta ọrịa: Ejikọtara ya na ọtụtụ enzymes nchọpụta ọrịa, dị ka ihe e ji eme ngwa nchọpụta ọrịa.
Ọkwa nri ahụike: A na-erekarị ngwaahịa NADH n'ụdị ihe mgbakwunye nri n'ahịa Europe na America. E nwere ọtụtụ ụdị ngwaahịa NADH n'ahịa, mmetụta nkwalite ahụ na-elekwasị anya na mgbochi ịka nká, na-enyere ndị nwere circadian aka.nsogbu elekere iji belata ike ọgwụgwụ, melite ọnọdụ uche, ma melite ikike nghọta na ọrụ anụ ahụ nke ndị na-enweghị ụra nke ọma; na mgbakwunye, enwere ude mmiri mmiri, gel ezé, wdg. anaghị eji ngwaahịa. Ebe ọ bụ na ewepụtara ngwaahịa nkwadebe mbụ nke NADH.na 1996, ọtụtụ ndị Europe na America anabatala ya. Ya mere, ihe fọrọ nke nta ka ọ bụrụ ụlọ ọrụ niile dị mkpa na Europe na America emepụtala ụdị nkwadebe NADH nke ha.
