Coeliac disease It is associated with other autoimmune diseases, such as diabetes mellitus type 1 and thyroiditis, among others. Coeliac disease is caused by a reaction to gluten, a group of various proteins found in wheat and in other grains such as barley and rye. Moderate quantities of oats, free of contamination with other gluten-containing grains, are usually tolerated. The occurrence of problems may depend on the variety of oat. It occurs in people who are genetically predisposed. Upon exposure to gluten, an abnormal immune response may lead to the production of several different autoantibodies that can affect a number of different
Prolamin Prolamin Prolamins are a group of plant storage proteins having a high proline content and found on plant materials mainly like in the seeds of cereal grains: wheat (gliadin), barley (hordein), rye (secalin), corn (zein), sorghum (kafirin) and as a minor protein, avenin in oats. They are characterised by a high glutamine and proline content and are generally soluble only in strong alcohol [70-80%] solutions, light acids, and alkaline solution. They do not coagulate in heat. They hydrolyse into prolin and ammonia. Some prolamins, notably gliadin, and similar proteins found in the tribe Triticeae (see Triticeae glutens) may induce coeliac
