NAD⁺, NADP⁺, NADPH
NAD⁺ is a coenzyme that plays an important role mainly in catabolic processes, while NADP is important in anabolic processes as hydrogen carriers.

Nicotinamide adenine dinucleotide, or NAD⁺, consists of two nucleotides, one of which contains an adenine base and the other consists of nicotinamide.
In powdered form, it is white, hygroscopic and easily soluble in water.
NAD⁺ is a co-enzyme in metabolic processes. It is responsible for transporting hydrogen in energy-releasing, catabolic processes. It is easily reduced; it acts as a hydrogen acceptor in reactions.
Occurrence and production
It can be found in all living cells. It mostly occurs in animal source foods, while plant-source foods contain it in relatively small amounts.
NAD⁺ is used in enzymatic analysis in biochemical and clinical laboratories. Its reduced form, NADH, is used in dietary supplements.
Enzymes are protein molecules catalyzing biochemical reactions. Their activity can be regulated.
ATP is the main source of energy for cells.
An acyl-carrier coenzyme taking part in both anabolic and catabolic processes.
A crystalline compound found in nucleic acids, coenzymes, nucleotides and nucleosides.
It is also used as a food additive, limescale and rust remover.
A heterocyclic aromatic organic compound, its derivatives include guanine and adenine.
The open-chain version of ribose, which occurs naturally in nucleic acids, coenzymes, nucleotides and nucleosides.
A compound ion formed when a phosphoric acid molecule releases a proton.
