Prolamines are a group of plant storage proteins that provide nutrition for seedlings. The term includes several proteins, each with different biological functions. Synonyms for prolamine include gliadin, hordein, zein, and avenin. Gliadin is found in wheat, hordein in barley, zein in corn, and avenin in oats. These proteins are known for their elasticity and are often used in the production of dough for baked goods. Prolamines can also cause health problems for individuals with gluten intolerance or celiac disease, as they trigger an immune response in the body. It is important to understand the different forms and synonyms of prolamine for both nutritional and medical purposes.
