Kinetic studies of amino acid uptakes into brush border membrane vesicles (BBMVs) (A) Time course of L-leucine (1.0 mM) uptake by brush border membrane vesicles (BBMVs); (B) Time course of L-cysteine (1.0 mM) uptake; (C) Time course of L-glutamic acid (1.0 mM) uptake and (D) Time course of L-proline (1.0 mM) uptake with (in the presence of NaSCN) or without (in the presence of KSCN) sodium-gradient. *p < 0.05, **p < 0.01, ***p < 0.001 vs CO. No differences between groups were found in Na⁺-independent transport for the four amino acids studied.
