    • -4 M solution of amino acid picrate in doubly distilled water (source aqueous phase) was carefully added into the space between the internal wall of the vessel and the external wall of the glass tube. The glass tube itself was filled with 20 ml of doubly distilled water (receiving aqueous phase). Thus, this glass tube separates the two aqueous phases (source and receiving), and the organic layer (liquid chloroform membrane) lies below them and bridges them across the separation by the central glass tube. The chloroform phase was stirred with a magnetic stirrer at 100 rpm for 6 h at 293 ± 1 K. Each experiment was repeated three times and the results were averaged. Amino acid transport was checked by monitoring changes in picrate anion concentration in the source and the receiving phases and in the chloroform by UV measurements (λ = 357 nm). Additionally, the extraction of tryptophan into chloroform and the receiving aqueous phase was also checked by the appearance of an absorption band at λ = 220 nm.
