Research question

What is the NAD+/NADH couple?

The short answer

Answered from published research literature only. It describes what that literature examines; it is not a statement about use in people. NAD+ is investigational research material and is not an approved product.

NAD+ is a dinucleotide coenzyme, not a peptide. In biochemistry it functions as a redox carrier, cycling between the oxidised NAD+ and reduced NADH forms as it shuttles electrons between reactions.40693873

It is also used as a defined laboratory reagent, and its biosynthetic pathway has been characterised directly.40693873
