For protein amino acids, a three-letter code has been used. Values followed by different letters (a, b) within a row are significantly (p < 0.05) different by Bonferroni post-test. *, ** indicate significant at p < 0.05 and p < 0.01, respectively. §, Cys amount was evaluated after performic acid oxidation. n.d. not determined.
