Be careful not to confuse the terms hydrogenation and dehydrogenation with hydration and dehydration - the latter terms refer to the gain or loss of water, while the former terms refer to the gain or loss of hydrogen.

Sustainable synthesis of N-heterocycles in water using alcohols following the double dehydrogenation strategy. It is, however, important in a larger metabolic context: as a general rule, redox enzymes involved in catabolism (the breakdown of large molecules) typically use the non-phosphorylated coenzyme, while those involved in anabolism (biosynthesis of large molecules from small precursors) use the phosphorylated coenzyme.

Alcohols are unreactive and require strong inorganic oxidants to convert to synthetically useful carbonyl compounds. The most important of these is a molecule called nicotinamide adenine dinucleotide. Please note: If you switch to a different device, you may be asked to login again with only your ACS ID. \(NAD^+\) and \(NADP^+\) both function in biochemical redox reactions as hydride acceptors: that is, as oxidizing agents. Synthetic organic chemists have at their disposal a wide range of other reducing and oxidizing reagents with varying specificities and properties, many of which you will learn about if you take a course in laboratory synthesis.
