Question

Write full form of NADP.

Answer 1

Hint:It is a triphosphopyridine nucleotide which is used in several anabolic reactions mainly in the dark reaction of photosynthesis, nucleic acid synthesis, lipid metabolism etc. All forms in cellular life require it.

Complete answer:
The full form of NADP is Nicotinamide adenine dinucleotide phosphate. NADP acts as an electron carrier that accepts electrons and forms NADPH i.e. Nicotinamide adenine dinucleotide phosphate hydrogenase. This coenzyme is the first enzyme in P450 systems of mitochondria where steroid hormones are synthesized. NAD (Nicotinamide adenine dinucleotide) and NADP are important coenzymes in cells. NAD with a phosphate group in its third carbon position makes NADP. In the nicotinamide ring, as the nitrogen atom is positively charged, oxidized forms of redox reagents are known as $\text{NA}{{\text{D}}^{\text{+}}}$

and $\text{NA}{{\text{D}}^{\text{+}}}$\[\text{NAD}{{\text{P}}^{\text{+}}}\] respectively. For biosynthesis and other functions, it requires a reducing agent NADPH. NADPH is produced by the reduction of \[\text{NAD}{{\text{P}}^{\text{+}}}\]. NADPH can also be produced by carbon metabolism or the mechanism of isocitrate dehydrogenase. The chemical formula and molar mass of NADP is-

Chemical Formula ${{\text{C}}_{\text{21}}}{{\text{H}}_{\text{29}}}{{\text{N}}_{\text{7}}}{{\text{O}}_{\text{17}}}{{\text{P}}_{3}}$

Note: As NADP is directly related to the light dependent reaction of photosynthesis, there is a need to have a clear knowledge about what is NADP and how it works in case of light phase or in other reactions also.
