Related to gliadin: Glutenin


Any of several prolamin proteins present in wheat grains, and constituting a component of wheat gluten. Gliadins can cause celiac disease in susceptible individuals by inducing a destructive immune response in the small intestine.

[Italian gliadina, from Medieval Greek glia, glue; see zoogloea.]


(ˈɡlaɪədɪn) or


(Cookery) a protein of cereals, esp wheat, with a high proline content: forms a sticky mass with water that binds flour into dough. Compare glutelin
[C19: from Italian gliadina, from Greek glia glue]


(ˈglaɪ ə dɪn, -dn)

1. a simple protein of cereal grains that imparts elastic properties to flour: used as a nutrient in high-protein diets.
2. any prolamin.
[1820–30; < Italian gliadina. See glia, -in1]
