NADP

(Science: chemical) nicotinamide adenine dinucleotide phosphate. A coenzyme composed of ribosylnicotinamide 5'-phosphate (nmn) coupled by pyrophosphate linkage to the 5'-phosphate adenosine 2',5'-bisphosphate. It serves as an electron carrier in a number of reactions, being alternately oxidised (NADP_) and reduced (nADPH).

Chemical name: Adenosine 5'-(trihydrogen diphosphate), 2'-(dihydrogen phosphate), P'-5'-ester with 3-(aminocarbonyl)-1-beta-D-ribofuranosylpyridinium, inner salt A coenzyme similar to NAD and present in most living cells but serves as a reductant in different metabolic processes.Shorthand version of nicotinamide adenine dinucleotide, a [[ coenzyme that can accept hydrogen.

Spectrophotometry - why can't some products be read?

... dehydrogenase in regards to spectrophotometry. The reaction I'm given is: glucose + ATP ----(hexokinase)---> G-6-P + ADP G-6-P + NADP+ <---(G-6-P dehydrogenase)---> 6-phosphogluconolactone + NADPH The above is just for your information. Any way, I'm told that the reason ...

Photosynthesis question...

... in the electron transport chain. This proton gradient is used to synthesize ATP using chemiosmosis, and the electrons are eventually passed to NADP+ reductase, which uses the two protons to synthesize 2 NADPH molecules. The NADPH enters the Calvin cycle to reduce CO2 to sugars.

Photosynthesis question...

... used by the molecules in the electron transport chain to transport positive H ions from the stroma into the inner thylakoid space.Is this molecule NADP?and where do they get the positive H ion from?Thanks in advance!

NADPH expiry

Dear All, I assume that many of you (or at least some) of you has worked with NADPH In my project now, I need NADPH, but the journal said that NADPH could be substituted by NADPH generating system, which consist of NADP, G6P, and G6PD. Well the pioneer of this ...

Re: Chloroplast

It sounds like your chromogenic redox reagent is standing in for NADPH/NADP+. Normally thylakoid electron transport sets up an H+ gradient that spills back through an ATPase to make ATP from ADP and Pi. If you supply ADP and Pi, you are making it easier ...
