Glutelin
Overview
Overview
Glutelins are soluble in dilute acids or bases, detergents, chaotropic or reducing agents. They are generally prolamin-like proteins in certain grass seeds. glutenin is the most common glutelin as it is found in wheat and is responsible from some of the refined baking properties in bread wheat. The glutelins of barley and rye[1] have also been identified.
Typically there are HMW and LMW glutelins in these species, they crosslink with themselves and other proteins during baking via disulfide bonds.
A HMW glutelin (glutenin) of the grass tribe Triticeae can be sensitizing agents for coeliac disease in individuals who possess the HLA-DQ8 class II antigen receptor gene.[2] (not yet characterized to the epitope level)
