FIG. 4.
A: Glutamine flux, glutamine plasma concentration, and absolute conversion rate of glutamine to glutamate (mean ± SE) in A−β+ KPD patients and control subjects (N = 9 for KPD, N = 7 for control subjects). B: Fractional synthesis rate of glutamate from glutamine, oxidation of glutamate carbon (derived from glutamine), and glutamate plasma concentration (mean ± SE) in A−β+ KPD patients and control subjects. *P < 0.05; †P = 0.06 (N = 9 for KPD, N = 7 for control subjects).
