    Study Notes

    NADPH in RBCs

    • NADPH is essential for maintaining reduced glutathione, which protects RBCs from oxidative damage

    HMP Shunt Pathway

    • The main product of the oxidative phase of the HMP shunt pathway is NADPH

    Glucose 6 Phosphate Dehydrogenase Deficiency

    • Deficiency in glucose 6 phosphate dehydrogenase in RBCs can lead to hemolytic anemia

    NADPH in WBCs

    • NADPH is necessary for the respiratory burst mechanism in WBCs, which is crucial for killing engulfed microorganisms

    HMP Shunt Pathway and Lipids

    • The HMP shunt pathway is involved in the synthesis of fatty acids and cholesterol
