Methionine restriction and cysteine restriction induce distinct changes in plasma amino acid concentrations. Although SAAR changed plasma concentrations of glutamic acid (a), glycine (b), and lysine (c), these amino acids did not show dose response to either MR or CR. A strong dose response was exhibited by plasma histidine (d), methionine (e), phenylalanine (f), serine (g), threonine (h), and tryptophan (i) to CR.
