WitrynaIf the reaction is run in 3 H 2 O, no 3 H is found in the NADH produced. This suggests a hydride mechanism (or a proton transfer mechanism with no exchange of solvent). … Nicotinamide adenine dinucleotide (NAD) is a coenzyme central to metabolism. Found in all living cells, NAD is called a dinucleotide because it consists of two nucleotides joined through their phosphate groups. One nucleotide contains an adenine nucleobase and the other nicotinamide. NAD exists in two forms: an oxidized and reduced form, abbreviated as NAD and NADH (H for hydrogen), r…
