the transport of the naturally occurring amino acids , alanine , proline , and leucine was defined by studies of : ( 1 ) competitive inhibition with the system-specific synthetic amino acids , methyl-aib and bch , ( 2 ) the effect of the transcellular sodium gradient on transport , and ( 3 ) evaluation of the time-dependent increase of transport in amino acid-deficient medium ( adaptation ) .
