Globulins are characterised by solubility in dilute saline as opposed to the more typical cereal proteinssuch as glutenand zein are prolamines (prolamins).
Trier [10] defined coeliac disease as "a chronic condition in which there is a characteristic mucosal lesion of the small intestine which impairs nutrient absorption by the involved bowel and which improves on withdrawal of wheat gliadins and barley, rye and oat prolamines from the diet".
