Triticeae glutelins presented by DQ2 is some coeliacs. The glutelins of barley and rye have also been identified. There are four major classes of seed storage proteins&colon; albumins, globulins, prolamins and glutelins. Similarly, glutelins found in wheat are typically called glutenins. Within wheat, prolamins are called gliadins and glutelins are called glutenins. Modern analysis now considers glutelins as a low-solubility subclass of prolamins. Glutelins are the primary form of energy storage in the endosperm of rice grains. Glutelins are soluble in dilute acids or bases, detergents, chaotropic agents, or reducing agents.
