Fmoc-Cya-OH disodium salt is a protected derivative for the introduction of this highly polar amino acid. Cya-containing peptides are obtained by oxidation of cysteine or cystine, as a post-translational modification, as a by-product of peptide synthesis, or intentionally (by using oxidants such as H2O2/formic acid), for quantification of these sensitive amino acids.
