The HMP shunt serves two major purposes in cellular metabolism. It generates ribose 5-phosphate used in the synthesis of nucleic acids. It also produces NADPH, a substance used in a number of synthetic pathways. NADPH protects red cells against oxidative damage. It is also used as part of the respiratory burst in phagocytes. In addition, the enzyme fatty acid synthase requires NADPH. Fatty acid synthesis will be impaired in the absence of normal NADPH production by the HMP shunt.
