Amino acid sequences of synthetic peptides and substituted peptides used in this study (single letter code)

*Residues 56–68 of α-9 gliadin was synthesised, compared with the sequence published.6 This was because the synthetic sequence 57–68 was found to be unstable at the N terminal glutamine residue, which was partially cyclised forming pyroglutamic acid.
