441:. Individuals with celiac disease exhibit a lifelong intolerance of wheat, barley and rye – all of which contain prolamins. The main problem with this disease is that it often goes unrecognized for many years, in which case it can cause serious damage to several organs, and most cases currently remain unrecognized, undiagnosed and untreated.
420:. This is done because gliadins are soluble in alcohol and cannot be mixed with other foods (like milk) without changing the food's qualities. Deamidated gliadin is soluble in water. The cellular immunity to deamidated α-/β-gliadin is much greater than α/β-gliadin and can result in symptomatic gluten-sensitive enteropathy.
