Metabolite Identification
Common NameCasomorphin
DescriptionCasomorphin is a 7-residue opiod peptide (Tyr-Pro-Phe-Pro-Gly-Pro-Ile) peptide derived from the milk protein casein. Casein is one of the major proteins in the milk of all mammals including cows, goats, and humans. It has been reported that urine samples from people with autism, celiac disease and schizophrenia contain high amounts of the casomorphin peptide. These peptides could also be elevated in other disorders such as chronic fatigue, fibromyalgia, and depression based on anecdotal reports of symptom remission after exclusion of wheat and dairy. The scientific evidence for this diet and its effects is still disputed.
