The pentose phosphate pathway is a process used to generate NADPH and pentoses (5-carbon sugars). This pathway is composed of two distinct phases. The first is the oxidative phase, in which NADPH is generated, and the second is the non-oxidative synthesis of 5-carbon sugars. This pathway is an alternative to glycolysis. Although it does involve oxidation of glucose, its primary role is anabolic rather than catabolic.
