Pentose fosfaat pathway
WebThe pentose phosphate pathway occurs in the cytosol consists of two distinct phases, the oxidative and non-oxidative. As for the former, the primary result is the conversion of glucose-6-phosphate (G6P) into ribulose-5-phosphate and CO2 and the generation of reduced NADPH.

WebIt is a ketose sugar formed from ribulose-5-phosphate. Although previously thought of mainly as an intermediary in the pentose phosphate pathway, recent research reported that the sugar has a role in gene expression, mainly by promoting the ChREBP transcription factor in the well-fed state. WebThe elucidation of the pentose phosphate pathway had now been accomplished. It consisted of two branches, an oxidative branch in which the hexose, glucose 6-phosphate, was converted to pentose phosphate and carbon dioxide with the reduction of two molecules of TPN, and a non-oxidative branch, in which three molecules of pentose …
Web25. okt 2024 · One of these pathways is the pentose phosphate pathway, which plays an integral role in producing both NADPH and the five-carbon sugar ribose. NADPH provides the cell with an energy source for reductive biosynthesis and detoxification of free radicals, while ribose is an essential component in the synthesis of both purine and pyrimidine ...
