Clinical Significance
Gliadins are wheat proteins which are poorly soluble in saline and require extraction using alcohol. Omega-5- gliadin (Tri a 19 or f416), is a well-characterized gliadin which is an important allergen in childhood wheat allergy and is also strongly associated with the wheat-dependent exercise-induced anaphylaxis (WDEIA) syndrome.
