Gliadin
Historical document, translated for reference. It reflects medical knowledge of the 1920s–30s and is not medical advice.
Summary
Gliadin is a protein from the prolamine group found alongside glutenin in wheat grains. It lacks glycine and lysine, meaning young animals fed gliadin as their sole protein experience stunted growth that can be corrected by adding lysine, though it serves as a complete dietary protein for adults.
Encyclopedia entry (1928–1936)
GLIADIN, a protein substance from the group of so-called prolamines, contained along with another protein, glutenin, in wheat grains. Gliadin does not contain glycine and lysine. When young animals are fed a diet containing gliadin as the sole protein, growth arrest and impaired development are observed, which can be cured by the addition of lysine to the food. For adult animals, gliadin is a nutritionally complete dietary protein.
