Application

As a reagent, NADH can be used in enzyme cycling assays to amplify detection of activity of biologically relevant enzymes or metabolites present in low concentrations.NADH has been used in MDH (malate dehydrogenase) enzymatic activity assay.NADH has been used in lactate dehydrogenase (LDH) enzymatic activity assay, glutamate-cysteine ligase activity assay and fructose 2,6-bisphosphate assay.

Biochem/Physiol Actions

NADH is a coenzyme that functions as a regenerating electron donor in catabolic processes including glycolysis, β-oxidation and the citric acid cycle (Krebs cycle, TCA cycle). It participates in cell signaling events as well, for example as a substrate for the poly (ADP-ribose) polymerases (PARPs) during the DNA damage response. The NAD⁺/NADH dependent sirtuins play key roles in stress responses during events involving energy metabolism, with implications in cancer biology, diabetes and neurodegenerative disease.
