1. Nicotinamide adenine dinucleotide

   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), respectively. In metabolism, NAD is involved in redox reactions, carrying electrons from one reaction to another. The cofactor is, therefore, found in two forms in cells: NAD+ is an oxidizing agent, accepting electrons from other molecules and becoming reduced; with H+, this reaction forms NADH, which can be used as a reducing agent to donate electrons. These electron transfer reactions are the main function of NAD. It is also used in other cellular processes, most notably as a substrate of enzymes in adding or removing chemical groups to or from, respectively, proteins, in posttranslational modifications. Because of the importance of these functions, the enzymes involved in NAD metabolism are targets for drug discovery. In organisms, NAD can be synthesized from simple building-blocks (de novo) from either tryptophan or aspartic acid, each a case of an amino acid. Alternatively, more complex components of the coenzymes are taken up from nutritive compounds such as niacin; similar compounds are produced by reactions that break down the structure of NAD, providing a salvage pathway that recycles them back into their respective active form. Some NAD is converted into the coenzyme nicotinamide adenine dinucleotide phosphate (NADP); its chemistry largely parallels that of NAD, though predominantly its role is as a cofactor in anabolic metabolism. The NAD+ chemical species' superscripted addition sign reflects the formal charge on one of its nitrogen atoms; this species is actually a singly charged anion – carrying a (negative) ionic charge of 1 – under conditions of physiological pH.

1. nicotinamide adenine dinucleotide

   Nicotinamide adenine dinucleotide (NAD) is a coenzyme found in all living cells. It is a critical coenzyme for enzymes that fuel reduction-oxidation reactions, carrying electrons from one reaction to another. This action facilitates the release of energy stored in nutrients, which is transformed into a form of energy usable by cells. NAD exists in two forms, an oxidized (NAD+) and reduced (NADH) state. Both forms play crucial roles in cellular metabolism and energy production.

1. Nicotinamide adenine dinucleotide

   Nicotinamide adenine dinucleotide, abbreviated NAD+, is a coenzyme found in all living cells. The compound is a dinucleotide, since it consists of two nucleotides joined through their phosphate groups. One nucleotide contains an adenine base and the other nicotinamide. In metabolism, NAD+ is involved in redox reactions, carrying electrons from one reaction to another. The coenzyme is, therefore, found in two forms in cells: NAD+ is an oxidizing agent – it accepts electrons from other molecules and becomes reduced. This reaction forms NADH, which can then be used as a reducing agent to donate electrons. These electron transfer reactions are the main function of NAD+. However, it is also used in other cellular processes, the most notable one being a substrate of enzymes that add or remove chemical groups from proteins, in posttranslational modifications. Because of the importance of these functions, the enzymes involved in NAD+ metabolism are targets for drug discovery. In organisms, NAD+ can be synthesized from simple building-blocks from the amino acids tryptophan or aspartic acid. In an alternative fashion, more complex components of the coenzymes are taken up from food as the vitamin called niacin. Similar compounds are released by reactions that break down the structure of NAD+. These preformed components then pass through a salvage pathway that recycles them back into the active form. Some NAD+ is also converted into nicotinamide adenine dinucleotide phosphate; the chemistry of this related coenzyme is similar to that of NAD+, but it has different roles in metabolism.
