Triticeae glutens proteins and the level of subcomponents, with bread wheat having the highest protein content and a complex mixture of proteins derived from 3 grass species ("Aegilops speltoides", "Aegilops tauschii strangulata", and "Triticum monococcum"). Triticeae seed proteins fall into four groups: Of these proteins the last two, prolamin (in wheat – gliadin) and glutelin (in wheat – glutenin) form the classically defined gluten components in wheat. Triticeae glutens are primarily important to a developing definition 'gluten-free' in dietary treatments for gluten sensitivity which are intended to exclude pathogenic proteins from the diet of susceptible individuals (namely coeliac disease). The poisonous motifs
Gluten immunochemistry its genome contains chromosomes derived from two goat grass species and a primitive wheat species. The positions of these motifs in different species, strains and isoforms may vary because of insertions and deletions in sequence. There are a large number of wheat variants, and a large number of gliadins in each variant, and thus many potential sites. These proteins once identified and sequenced can be surveyed by sequence homology searches. HLA-DQ recognition of gliadin is critical to the pathogenesis of gluten-sensitive enteropathy, it also appears to be involved in idiopathic gluten sensitivity (See:Understanding DQ Haplotypes and DQ isoforms on the
