Collection: NAD(P)(H) and Analogs

NAD(P)(H) and Analogs — contains nicotinamide adenine dinucleotide coenzymes in both oxidized and reduced forms -- NAD, NADH, NADP, NADPH -- along with thio analogs and various salt forms, which act as electron carriers in enzymatic redox reactions in cellular metabolic pathways.

NAD(P)(H) coenzymes in this category are used by biochemistry and molecular biology researchers as cofactors in dehydrogenase enzyme activity assays, redox reactions in glycolysis, the citric acid cycle, and photosynthesis. Reduced forms such as NADH and NADPH are commonly used as substrates for spectrophotometric monitoring, while thio-NAD analogs are used as selective tracers in enzymatic kits for quantifying metabolites and nutrients.

Example products in this collection: TCI T2980 Thionicotinamide Adenine Dinucleotide Disodium Salt reduced form [for Biochemical Research], TCI C0379 1184-16-3 beta-Nicotinamide Adenine Dinucleotide Phosphate Sodium Salt Hydrate, oxidized form [for Biochemical Research], TCI T2979 4090-29-3 Thionicotinamide Adenine Dinucleotide oxidized form [for Biochemical Research], TCI D0919 53-84-9 beta-Nicotinamide Adenine Dinucleotide oxidized form [for Biochemical Research], TCI A3132 143621-35-6 2-[(3-Aminopyridin-2-yl)methylene]hydrazinecarbothioamide, TCI D0920 606-68-8 beta-Nicotinamide Adenine Dinucleotide Disodium Salt, reduced form [for Biochemical Research], TCI T0521 2646-71-1 beta-Nicotinamide Adenine Dinucleotide Phosphate Tetrasodium Salt reduced form [for Biochemical Research], TCI N0943 53-59-8 beta-Nicotinamide Adenine Dinucleotide Phosphate [for Biochemical Research].

Make sure the oxidized/reduced form (NAD+ vs NADH) and salt type (sodium, tetrasodium) match the enzymatic assay protocol, and pay attention to the purity and storage stability of the reduced forms, which are easily oxidized. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.

Other categories at the same level under Nucleosides, Nucleotides, Oligonucleotides are often used together in a single laboratory workflow:

• Nucleoside Analogs
• Nucleobases and their Analogs
• Nucleosides
• Nucleotides
• Nucleotide Analogs
• Oxidoreductase Coenzymes [Nucleosides, Nucleotides, Oligonucleotides]

This collection is further divided into 1 more specific group:

• Enzymatic Kits for the Quantitation of Nutrients and Metabolites
