Gliadin is a gluten component. This peptide is derived from amino acid residues 57-68 of a9-gliadin and represents an immunodominant epitope that has been shown to elicit HLA-DQ2-restricted T-cell responses in celiac patients. This epitope is resistant to pancreatic proteolysis. - Pyroglutamyl (pGlu) peptides may spontaneously form when either Glutamine (Q) or Glutamic acid (E) is located at the sequence N-terminus. The conversion of Q or E to pGlu is a natural occurrence and in general it is believed that the hydrophobic ?-lactam ring of pGlu may play a role in peptide stability against gastrointestinal proteases. Pyroglutamyl peptides are therefore considered a normal subset of such peptides and are included as part of the peptide purity during HPLC analysis.
