[ Sen. 4, subscore: 1.00 ]: Formation of such a proton-bound dimer is facile via a protonation of the tryptophan gamma-carbon atom as suggested by density functional theory ( DFT ) calculations .
[ Sen. 6, subscore: 1.00 ]: The C ( beta ) -C ( gamma ) bond cleavage of a tryptophan residue also can occur directly from peptide radical cations containing a basic residue .

[ Sen. 2, subscore: 1.00 ]: Two levels of lysine , 900 and 1800 mg , and three of tryptophan , 260 , 390 , and 520 mg , were tested .
[ Sen. 3, subscore: 1.00 ]: Lysine exerted a significant effect ( P less than 0 . 05 ) on nitrogen retention but tryptophan did not .
[ Sen. 4, subscore: 1.00 ]: When consumed in conjunction with at least twice the reported minimal requirements of other essential amino acids , 900 mg of lysine induced mean daily balances of 0 . 15 +/- 0 . 18 , 0 . 19 +/- 0 . 14 , and 0 . 22 +/- 0 . 21 g , respectively , in response to the three levels of tryptophan ; and 1800 mg of lysine caused retentions of 0 . 75 +/- 0 . 14 , 0 . 77 +/- 0 . 21 and 0 . 71 +/- 0 . 15 g .
