Transport of an amino compound, tryptophan, was carried out with a liquid membrane incorporating a lipophilic aldehyde, 4-octadecyloxybenzaldehyde, as a carrier. In the present membrane transport system, a reversible organic reaction, Schiff base formation between the amino group in tryptophan and the formyl moiety in the carrier was utilized as a molecular recognition reaction.
