Gluten exorphin B4

(2S)-2-({[2-({[2-({[(2S)-2-amino-3-(4-hydroxyphenyl)propanoyl]oxy}amino)acetyl]oxy}amino)acetyl]oxy}amino)-3-(1H-indol-3-yl)propanoic acid

C24H27N5O9 (529.1808692000001)


Gluten exorphin B4 is a tetrapeptide with the sequence Tyr-Gly-Gly-Trp. Gluten exorphins are a group of opioid peptides which are formed during digestion of the gluten protein. It has been hypothesized that people with autism and schizophrenia have abnormal leakage from the gut of these compounds, which then pass into the brain and disrupt brain function. This is partly the basis for the gluten-free, casein-free diet. The scientific evidence for this diet and its effects is still disputed.
