Inhibition kinetics of 1,2,3,4,6-penta-O-galloyl-β-d-glucopyranose (PGG) and catechin gallate (CG) against hPL. Left: (A) The inhibition kinetic plots, (C) Lineweaver-Burk plots, and (E) the secondary plots of PGG against hPL-catalyzed 4-MUO hydrolysis. Right: (B) The inhibition kinetic plots, (D) Lineweaver-Burk plots, and (F) the secondary plots of CG against hPL-catalyzed 4-MUO hydrolysis. All data are shown as means ± SD (n = 2).
