Gluten is the protein component of Triticum aestivum (Wheat) flour. It consists of numerous proteins, which are of 2 different types responsible for different physical properties of dough: the glutenins, which are primarily responsible for the elasticity, and the gliadins, which contribute to the extensibility. The glutenins themselves are of 2 different types, termed low and high
[1]
molecular weight subunits. The latter have unusual structures: a central region contains multiple tandem repeats of blocks of amino acids, forming a loose helix based on β reverse turns, and is flanked by globular regions, which can be cross-linked by disulphide bonds. The result is an elastic network in which the elasticity may derive from the cross-linking, the helical structure, or a combination of these

.

The gliadins are also of different types (e.g., alpha/beta or gamma) and, like the glutenins, contain repetitive sequences
[3]
that form loose helical structures, but are usually associated with more extensive non-repetitive regions, which are compact and globular
[4]
.

This family also includes avenin-like proteins, which are considered atypical gluten constituents
