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).

Storage protein of the dry weight of the seed can be composed of storage proteins. The best known storage protein in wheat is the prolamin gliadin, a component of gluten. Storage protein Storage proteins serve as biological reserves of metal ions and amino acids, used by organisms. They are found in plant seeds, egg whites, and milk. Ferritin is an example of a storage protein that stores iron. Iron is a component of heme, which is contained in the transport protein, hemoglobin and in cytochromes. Some storage proteins store amino acids. Storage proteins' amino acids are used in embryonic development of animals
