Figure 4. Permeability studies of enkephalin and carbohydrate-derived enkephalins.

Figure 4

A) Apparent permeability (P app (cm/s) of enkephalin and glycosylated enkephalins. (p value <0.05) B) Apparent permeability of enkephalin and glycosylated enkephalin in the presence of the SGLT1 inhibitor phlorizin (horizontal lines) and the GLUT2 inhibitor phloretin (diagonal lines). P app values in the presence of inhibitor was compared to that of compound in the absence of any inhibitor (p value <0.05) Data reported is the mean ± S.D. (n = 3).
