What symptom is barley allergy?

summary

Gluten is a kind of protein existing in wheat, barley and rye. Generally speaking, after the protein enters the gastrointestinal tract, it will be digested into a single amino acid, and then absorbed by the small intestine to become a nutrient. However, gluten can not be completely decomposed into a single amino acid, and some small fragments containing several amino acids will be retained. Such fragments are called "polypeptides.". Polypeptides can trigger the immune response of human body, which is also the reason why some proteins still have some biological activities after oral administration.
