WebThe PPP is a multienzyme pathway that shares a common starting molecule with glycolysis, glucose-6-phosphate ( Figure 2 ). The PPP gives rise to several critical products for cancer metabolism, including a pentose (5-carbon sugar), ribose-5-phosphate. Ribose-5-phosphate is a precursor for the synthesis of nucleotides and nucleic acids.
