Linked from

The 37 pages that link to Nicotinamide adenine dinucleotide, each with the reason it gives.

• NucleotideRelated: Its structure includes an adenine nucleotide joined to another nucleotide-like unit.

• Cellular respirationRelated: Respiratory pathways load NADH with electrons that feed the electron transport chain.

• GlycolysisRelated: Glycolysis reduces NAD+ to NADH while oxidizing a sugar intermediate.

• MetabolismRelated: This electron carrier links oxidation reactions to energy-producing pathways.

• ATPCompared with: NADH chiefly transfers reducing power, unlike ATP’s widespread role in energy coupling.

• Lactic acid fermentationRelated: Fermentation depends on recycling NADH back to NAD⁺.

• Citric acid cycleRelated: Several cycle reactions transfer electrons from carbon intermediates to NAD⁺.

• Alcoholic fermentationRelated: Its oxidized form, NAD⁺, must be replenished for glycolysis to continue.

• Beta oxidationRelated: A later oxidation step reduces NAD⁺ to NADH in every round.

• Lactate dehydrogenaseRelated: Its oxidized and reduced forms, NAD⁺ and NADH, are interconverted in the enzyme’s reaction.

• NADPHCompared with: Unlike NADP+, it lacks the phosphate that distinguishes NADPH's coenzyme family.

• Flavin adenine dinucleotideCompared with: NAD usually diffuses between enzymes, whereas FAD often remains tightly bound to one enzyme.

• DNA ligaseCompared with: Some bacterial DNA ligases use NAD+ rather than ATP as their adenyl-group source.

• NADHCompared with: NADH’s electron-donating capacity depends on its conversion back to NAD+.

• AdenineBroader topic: Its name and structure include an adenine-bearing nucleotide unit.

• Alcohol dehydrogenaseRelated: NAD⁺ accepts a hydride during many alcohol dehydrogenase reactions.

• PellagraRelated: Niacin supplies precursors for NAD, whose depletion impairs energy metabolism in pellagra.

• CoenzymeBroader topic: Its NAD⁺ and NADH forms illustrate how coenzymes shuttle electrons.

• Pyruvate dehydrogenase complexRelated: The complex reduces NAD+ to NADH during acetyl-CoA formation.

• RiboflavinCompared with: NAD and FAD both transfer electrons, but their structures and enzyme roles differ.

• Hydride transferBroader topic: NADH transfers hydride equivalents in numerous enzyme-catalyzed redox reactions.

• MalateRelated: Malate dehydrogenase couples malate conversion to the NADH/NAD⁺ redox pair.

• NicotinamideBroader topic: Nicotinamide supplies the vitamin-derived ring in this central metabolic coenzyme.

• Nicotinamide adenine dinucleotide phosphateNarrower topic: NADP is structurally derived from NAD by addition of a phosphate group.
