Descrição geral

3-Acetylpyridine adenine dinucleotide is a crystalline solid. 3-Acetylpyridine adenine dinucleotide is a prominent electron transporter in various enzymatic activities in which it is alternately oxidized. APAD has a more significant oxidation potential than NAD. NAD analogues, APAD, were electrochemically more effectively reduced than genuine NAD, and the stability of their reduced products was also significantly higher than NADH. In transhydrogenation processes with NADH or NADPH, APAD also operates as a proton acceptor.

Aplicação

Many molecules use 3-Acetylpyridine adenine dinucleotide as a signaling molecule, cofactor, or substrate. Various dehydrogenase processes use APAD instead of NAD as a hydrogen-accepting cofactor. The oxidative phosphorylation can be studied with ADAP. ADAP can also be used as a suitable substrate.

Ações bioquímicas/fisiológicas

APAD is an NAD analog with higher oxidation potential than NAD. It can substitute for NAD as a hydrogen-accepting cofactor in many dehydrogenase reactions; e.g. lactate dehydrogenase from Toxoplasma, Clonorchis, and Plasmodium, bacterial lipoamide dehydrogenase, as well as mammalian dehydrogenases. It can also act as a proton acceptor in various transhydrogenation reactions with NADH or NADPH.
