pentose phosphate pathway

pentose phosphate pathway (pentose shunt) A series of biochemical reactions that results in the conversion of glucose 6-phosphate to ribose 5-phosphate and generates NADPH, which provides reducing power for other metabolic reactions, such as synthesis of fatty acids. Ribose 5-phosphate and its derivatives are components of such molecules as ATP, coenzyme A, NAD, FAD, DNA, and RNA. In plants the pentose phosphate pathway also plays a role in the synthesis of sugars from carbon dioxide. In animals the pathway occurs at various sites, including the liver and adipose tissue.

hexose monophosphate shunt

hexose monophosphate shunt (pentose phosphate shunt) A metabolic pathway, alternative to that of glycolysis, of carbohydrate interconversion: hexose-6-phosphate is converted into pentose phosphate and carbon dioxide. The principal functions of the pathway are the production of deoxyribose and ribose sugars for nucleic acid synthesis; the generation of reducing power in the form of NADPH for fatty acid and/or steroid synthesis; and the interconversion of carbohydrates. Parts of the pathway are involved in the Calvin cycle in photosynthesis.
