- ... Eighteen references were selected for computation of the relative standard deviation in estimations of amino acids. Cysteine, tryptophan, tyrosine and methionine were associated with higher relative standard deviations than other amino acids. A mean relative standard deviation of about 8%, ranging from 5.9 to 14.1% depending on the amino acid, was observed between samples hydrolysed independently. ...
