Gliadin the formation of gluten. They are slightly soluble in ethanol and contain only intramolecular disulfide links. They also cause some of the best examples of food-derived pathogenesis. People with gluten-sensitive enteropathy (the severe form of which is celiac disease) are sensitive to α, β, and γ gliadins. Those with WD urticaria and Baker's asthma are sensitive to ω-gliadins. Gliadin can also serve as a useful delivery method for sensitive enzymes (such as superoxide dismutase, which is fused with gliadin to form glisodin) – this helps protect them from stomach acids that cause breakdown. For useful description of the gliadins see:
Anti-gliadin antibodies This antibody is a recommended testing protocol in a proposed revision of the Codex Alimentarius. The new standards came about in part because of new sensitive and specific testing procedures. These procedures are capable of detecting wheat or multiple cereals at concentrations as low as 1 part per million (PPM or 1 mg/kg). A new barley-sensitive ELISA called the R5 sandwich assay does not detect gluten in any of 25 pure oat varieties, but it does detect barley, wheat and rye. Anti-gliadin antibodies Anti-gliadin antibodies are produced in response to gliadin, a prolamin found in wheat. In bread wheat it
