The full form of NADPH is nicotinamide adenine dinucleotide phosphate hydrogen.
NADPH is a crucial reducing agent used in anabolic reactions, such as lipid and nucleic acid synthesis, which require a source of electrons. It is also involved in protecting cells from oxidative stress. It is produced during the light-dependent reactions of photosynthesis and used in the Calvin cycle to fix carbon dioxide.
In more detail:
- Nicotinamide: A derivative of niacin (vitamin B3).
- Adenine: A nucleobase found in DNA and RNA.
- Dinucleotide: Consisting of two nucleotides joined by a phosphate group.
- Phosphate: A salt or ester of phosphoric acid.
- Hydrogen: Refers to the hydrogen atom it carries, enabling its reducing power.
Therefore, NADPH is a coenzyme that carries electrons and is essential for various biochemical reactions.
