Gliadorphin (or gluteomorphin) is a 7-residue opioid peptide (Tyr-Pro-Gln-Pro-Gln-Pro-Phe) derived from the wheat protein gluten. Other related grains such as rye, barley and oats also contain the same sequence of amino acids found in gluten. Gliadorphin is very similar to casomorphin (a casein-derived peptide). Gliadorphin has been verified by mass spectrometry techniques to be present in urine samples of children with autism.
