The apparent affinities of various amino acids for the neutral amino acid transport system in rabbit ileum were determined by measuring the inhibition of L-methionine-(14)C influx across the brush border membrane. The apparent affinity was very low for compounds lacking an alpha-amino group, compounds with the alpha-hydrogen substituted by a methyl group, D-compounds, compounds with tertiary branching in the side chain, compounds with either a positive or negative charge in the side chain, and… CONTINUE READING
