The pentose phosphate pathway (PPP) is divided into an oxidative branch that makes pentose phosphates and a non-oxidative branch that consumes pentose phosphates, though the non-oxidative branch is considered reversible. (mdpi.com)
Glycolysis2
The more active of the 2 pathways, anaerobic glycolysis provides most of the high-energy phosphate bonds required for lens metabolism. (aao.org)
NADPH stands for nicotinamide adenine dinucleotide phosphate hydrogen. (lukimiko.com)
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. (lukimiko.com)
NADP^+ is converted to NADPH by attack of a hydride ion (H^-) and subsequent electronic rearrangement to neutralise the +ve nitrogen as shown in this link (the mechanism for NAD^+ and NADP^+ is the same): (b)During the light reactio n in photosynthesis, inorganic phosphate is added to ADP, forming ATP and NADP is reduced in the formation ofNADPH. (lukimiko.com)
Nicotinamide 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.It is used by all forms of cellular life. (lukimiko.com)
Adenosine triphosphate (ATP) and nicotinamide adenine dinucleotide phosphate (NADPH) are phosphorylated compounds present in organisms. (lukimiko.com)
Sugars1

Ribose2
Ribulose-5-phosphate is isomerized to ribose-5-phosphate or epimerized to xylulose-5-phosphate. (microbenotes.com)
Ribose-5-phosphate and xylulose-5-phosphate undergo reactions, catalyzed by transketolase and transaldolase, that transfer carbon units, ultimately forming fructose 6-phosphate and glyceraldehyde-3-phosphate. (microbenotes.com)
Levels of glucose-6-phosphate dehydrogenase are increased in the liver and adipose tissue when large amounts of carbohydrates are consumed. (microbenotes.com)
Glyceraldehyde-3-phospha1
The glyceraldehyde‐3‐phosphate can be converted into the 6‐carbon sugar phosphate called fructose‐6‐phosphate by the reactions of triose phosphate isomerase, aldolase, and fructose bisphosphase. (cliffsnotes.com)
Oxidative2
It forms ribulose 5-phosphate from 6-phosphogluconate: 6-phospho-D-gluconate + NAD(P)+ ⇌ {\displaystyle \rightleftharpoons } D-Ribulose 5-phosphate + CO2 + NAD(P)H + H+ It is an oxidative carboxylase that catalyses the decarboxylating reduction of 6-phosphogluconate into ribulose 5-phosphate in the presence of NADP. (wikipedia.org)
The reaction sequence in the Calvin-Benson cycle is from triose phosphates to pentose phosphates, the opposite of the typical direction of the non-oxidative PPP. (mdpi.com)
Pathways2
This reaction is a component of the hexose mono-phosphate shunt and pentose phosphate pathways (PPP). (wikipedia.org)
The reactions are also found in the pathways for gluconeogenesis and the pentose phosphate shunt. (cliffsnotes.com)
Enzyme2
The 5‐carbon sugar phosphates are interconverted by the action of epimerase and isomerase to yield ribulose‐5‐phosphate, which is phosphorylated by the enzyme ribulose phosphate kinase to make RuBP, the acceptor of CO 2 . (cliffsnotes.com)
Ribulose phosphate kinase is active only when a cystine disulfide on the enzyme is reduced to two cysteines. (cliffsnotes.com)
Ribulose2
The remaining carbons form ribulose-5-phosphate. (microbenotes.com)
Regeneration of ribulose bisphosphate occurs by the same reactions that occur in the hexose‐monophosphate shunt. (cliffsnotes.com)
