Knead to Know: Dough

Flour contains the gluten-forming proteins gliadin and glutenin. When these proteins are hydrated during mixing, they create a network known as gluten.

Gliadin is responsible for the flow and extensibility of the dough, and glutenin provides elastic properties. Together they form the typical visco-elastic properties vital to bread-making. During mixing, these bonds become strong enough to trap gas and form bubbles, which then expand during fermentation.
