β-Nicotinamide Adenine Dinucleotide, reduced form CAS:606-68-8

β-Nicotinamide adenine dinucleotide, reduced disodium salt has been used in the preparation of standard curve.One of the biologically active forms of nicotinic acid. Serves as a coenzyme of hydrogenases and dehydrogenases. NAD usually acts as a hydrogen acceptor, forming NADH which then serves as a hydrogen donor in the respiratory chain. Present in living cells primarily in the reduced form (NADPH) and is involved in synthetic reactions. Occurs in 2 forms, α-NAD and β-NAD, distinguished by the configuration of the ribosyl nicotinamide linkage. Only the β-anomer is bioactive.
