3-ACETYLPYRIDINE ADENINE DINUCLEOTIDE

3-Acetylpyridine NAD (APAD) is an analog of NAD⁺ (free acid) (nicotinamide adenine dinucleotide; ), a signaling molecule and cofactor or substrate for many enzymes. APAD has been used to study the mechanisms of oxidative phosphorylation. It can be reduced by transdehydrogenase from NADH (sodium salt) . It can be reduced more efficiently and is more stable than NAD⁺; thus, it is useful as a substitute.

ChEBI: 3-acetylpyridine adenine dinucleotide is an organic molecular entity.
