FIGURE 5.

Double‐log plots for binding constant and binding points for (a) linagliptin‐bovine serum albumin, (b) rabeprazole sodium‐bovine serum albumin, and (c) linagliptin‐rabeprazole sodium‐bovine serum albumin systems at 298, 308, and 318 K temperatures. Log (F ₀ – F)/F and log{[D]₀ – n [P]₀(F ₀ – F)/F} were expressed in the Y‐ and X‐axes, respectively. From the slope value, the number of the binding sites (n) and the antilogarithm values of intercept indicated the binding constant of the ligand
