Abstract

See full text

A method for quantitatively analyzing cysteine and cysteine includes a first step of adding a methyl-sulfurating agent to a sample that includes cysteine and cystine to obtain a methyl-sulfurated cysteine, a second step of adding a derivatizing agent to the methyl-sulfurated cysteine and the cystine to obtain a cysteine derivative and a cystine derivative, respectively, and a third step of quantifying the cysteine derivative and the cystine derivative.
