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
Wheat allergy high molecular weight glutenin subunit, and similar proteins in other "Triticeae" genera, enter the blood stream during exercise where they cause acute asthmatic or allergic reaction. One recent study of ω-gliadins demonstrated these gliadins are more similar to the bulk of oat avenins than α/β or γ gliadins but, so far, oat avenins have not been linked to WDEIA. Wheat may specifically induce WDEIA and certain chronic urticaria because the anti-gliadin IgE detects ω-gliadins expressed by most of the Gli-B1 alleles, but prolamins extracted from rye or wheat/rye translocates invoke almost no responses. The Gli-B1 gene in wheat, "Triticum aestivum",
