Biochemistry
  • Nicotinamide adenine dinucleotide, a coenzyme important in many biological oxidation reactions.

    • ‘There are several metabolic pathways for biosynthesis of nicotinamide adenine dinucleotide (NAD +) in bacteria.’
    • ‘In this study we have focused on the regeneration of the reduced form of nicotinamide adenine dinucleotide in the cell due to its key role in cellular metabolism.’
    • ‘The NAM nucleotide coenzymes nicotinamide adenine dinucleotide and nicotinamide adenine dinucleotide-phosphate are involved in hundreds of metabolic reactions.’
    • ‘These include things like thiamine pyrophosphate, pyridoxal phosphate and nicotinamide adenine dinucleotide.’
    • ‘This forms two ATPs, and two molecules of nicotinamide adenine dinucleotide, a carrier of high-energy hydrogens used in catabolic reactions.’
