The pentose phosphate pathway is a metabolic pathway parallel to glycolysis. Wikipedia

A chemical process that generates five-carbon sugars Wikipedia Disambiguation

The glucose-6-phosphate catabolic process in which, coupled to NADPH synthesis, glucose-6-P is oxidized with the formation of carbon dioxide and ribulose 5-phosphate; ribulose 5-P then enters a series of reactions interconverting sugar phosphat Wikidata

A metabolic pathway parallel to glycolysis that generates NADPH and pentoses as well as ribose 5-phosphate, the last one a precursor for the synthesis of nucleotides. Wiktionary
