Basic Breadmaking Part2: Gluten Formation
Gluten is the name for one of the two main structural components in any wheat dough or batter; the other being starch, something much more important in rye doughs.
It is a protein based material made from the bonding of two structural proteins in the wheat kernel, that I'll call G1 and G2.
In the presence of water G1 and G2 link up in a chemical bond that is both strong and stable, limited only by the amount of water available to G1 and G2.
