Triticeae glutens causing them to stretch out in solution. Deamidation of 20% of glutamine side chains to glutamate suffices to generate a soluble product. This renders gluten soluble enough without alcohol to mix with other products like milk. Individuals who suffer from gluten-sensitive enteropathy/coeliac disease have an adverse reaction to the gluten in cultivars of Triticeae when eaten. In addition to bread wheat, rye and barley (which have similar glutens) are known to cause symptoms in coeliacs. Between 2 and 10% of gluten sensitive individuals are also sensitive to oats, but it is not clear how much of this is due to
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
