The immunochemistry of triticeaeglutensTriticeaeglutens is important in several inflammatory diseases. It can be subdivided into innate responses direct stimulation of immune system , MHC class II class II mediated presentation HLA DQ , MHC class I class I meditiated stimulation of killer cells , and antibody recognition. The responses to gluten protein s and polypeptide regions differs according to the type of gluten sensitivity. The response is also dependent on the genetic makeup of the human leukocyte antigen genes.

Refimprove date November 2008 The term gluteome is used to describe the entire set of all gluten like proteins in grains, which consumption causes occurrence of clinical manifestations in celiac patients. These proteins include gliadin s and glutenin s from wheat, secalins from rye, hordein s from barley, avenins from oats and potentially homologues from other related grain species. Since not all grain storage proteins have been identified yet, the term gluteome often refers to the complete set of the known sequences of gluten and gluten like molecules. Alternatively, the word gluteome can depict the entire complement of grain storage proteins in a single grain species at a given time. The discipline of science dedicated to study gluteome is referred to as gluteomics . Category Glutens ... more details
Refimprove date November 2008 The word gluteomics describes the systematic study on the T cell stimulatory peptides in celiac disease . These peptides are derived from gluten or gluten like proteins. Usually the term gluteomics is used in the context of global approach to identify, target or detect large sets of the disease related sequences. The scientific methods usually employed by gluteomic studies include novel epitope identification by means of database searching with dedicated algorithms, studies on toxicity of fractions of gluten and or gluten like proteins, degradation of multiple T cell stimulatory sequences with the specific enzymes, and development of protocols for the detection of peptides implicated in the pathogenesis of celiac disease.

Unreferenced stub auto yes date December 2009 Secalin is a prolamin glyco protein found in the grain rye , Secale cereale . Secalin is one of the forms of gluten proteins that people with coeliac disease cannot tolerate, and thus rye should be avoided by people with this disease. It is generally recommended that such people follow a gluten free diet . In bread making with rye flour, this protein requires exposure to an acid such as lactic acid so that the bread will rise. This is usually achieved with a sourdough fermentation food ferment .

Glutenin also called glutelin or glutenine is the major protein within wheat flour , making up 47 of the total protein content. The glutenins are protein aggregates of high molecular weight HMW and low molecular weight LMW Protein subunit subunits with molar mass es from circa 200,000 to a few million, which are stabilized by intermolecular disulfide bond s, hydrophobic interaction s and other forces.

Hordein is a prolamin glycoprotein , present in barley and some other cereal s, together with gliadin and other glycoproteins such as glutelins coming under the general name of gluten . Some people are sensitive to hordein due to disorders such as celiac disease or gluten intolerance. Along with gliadin the prolamin gluten found in wheat , hordein is present in many foods and also may be found in beer. Hordein is usually the main problem for coeliacs wishing to drink beer. Coeliacs are able to find specialist breads that are low in hordein, gliadin and other problematic glycoproteins, just as they can find gluten free beer which either uses ingredients that do not contain gluten, or otherwise has the amounts of gliadin or hordein present controlled to stated limits.

The green or reddish green inflorescence is 2 to 6 centimeters long and about half a centimeter wide. Like other barleys the spikelets come in triplets. There is a large fertile central spikelet about a centimeter long and two smaller, often sterile spikelets on Pedicel botany pedicels , each 3 to 5 millimeters long.
