Transport of 1 mM concentration of VACV and GVACV across Caco-2 in the presence of 10 mM glycylsarcosine

	Permeability, P_app · 10⁶ cm/s
	− Gly-Sar (control)	+ Gly-Sar
Val-ACV	3.01 ± 0.21 × 10⁻⁶	1.61 ± 0.31^4-a
Gly-Val-ACV	2.99 ± 0.59 × 10⁻⁶	1.07 ± 0.13^4-b

Values are mean ± S.E. (n = 3–6).

↵4-a p < 0.05 compared with P_app of VACV.
↵4-b p < 0.05 compared with P_app of GVACV.
