NADNADH
NADNADH refers to the redox couple formed by nicotinamide adenine dinucleotide in its oxidized form (NAD+) and its reduced form (NADH). It functions as a central electron carrier in cellular metabolism, cycling between NAD+ and NADH as electrons are transferred during oxidation-reduction reactions.
In energy metabolism, NAD+ accepts two electrons and a proton to become NADH, which then donates electrons
The cellular ratio of NAD+ to NADH reflects redox state and regulates metabolic flux. A high NADH
NADH should be distinguished from NADPH, a related cofactor used mainly in biosynthetic reactions and antioxidant
