Nicotinamide adenine dinucleotide phosphate - Wikipedia
WEBNicotinamide adenine dinucleotide phosphate, abbreviated NADP+ or, in older notation, TPN (triphosphopyridine nucleotide), is a cofactor used in anabolic reactions, such as the Calvin cycle and lipid and nucleic acid syntheses, which require NADPH as a reducing agent ('hydrogen source').
4.3: NAD and NADP - Biology LibreTexts
WEBMay 14, 2022 · 4.3: NAD and NADP. Nicotinamide adenine dinucleotide (NAD) and its relative nicotinamide adenine dinucleotide phosphate (NADP) are two of the most important coenzymes in the cell. NADP is simply NAD with a third phosphate group attached as shown at the bottom of the figure.
Nicotinamide adenine dinucleotide - Wikipedia
WEBNicotinamide adenine dinucleotide ( NAD) is a coenzyme central to metabolism. [3] 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.
NADP+: Definition and Function | Biology Dictionary
WEBApr 28, 2017 · NADP + is a coenzyme that functions as a universal electron carrier, accepting electrons and hydrogen atoms to form NADPH, or nicotinamide adenine dinucleotide phosphate. NADP + is created in anabolic reactions, or reaction that build large molecules from small molecules. NADPH donates the hydrogen (H) and associated electrons, oxidizing the ...

Nicotinic acid adenine dinucleotide phosphate - Wikipedia
WEBNicotinic acid adenine dinucleotide phosphate ( NAADP) is a Ca 2+ -mobilizing second messenger synthesised in response to extracellular stimuli. Like its mechanistic cousins, IP 3 and cyclic adenosine diphosphoribose ( Cyclic ADP-ribose ), NAADP binds to and opens Ca 2+ channels on intracellular organelles, thereby increasing the intracellular ...

The phosphate makes a difference: cellular functions of NADP
WEBDec 2, 2013 · In its reduced form (NADPH), this molecule represents a universal electron donor, not only to drive biosynthetic pathways. Perhaps even more importantly, NADPH is the unique provider of reducing equivalents to maintain or regenerate the cellular detoxifying and antioxidative defense systems.
