The most important aspect of making high-quality bread isn't the embrace of old-fashioned techniques but rather the identification of what's essential among those techniques and the acceptance of the need to use those procedures, whatever the inconvenience or cost [Preface p.ix]
Insoluble proteins account for the remaining 80% of the proteins in the endosperm. They do not dissolve in water. The two insoluble proteins present in wheat are glutein and gliadin. Glutenin forms long, strong chains that seem to give wheat dough its strength, while gliadin strands bond to glutenin strands [...] (the nature of bonding between glutenin and gliadin is not completely understood), In order to bond, the two proteins must be in the presence of water. As they bond, they form a more complex protein called gluten. [Advanced Topic #1 Flour Composition and Milling Technology, p.174]

gluten A complex protein formed by the union of two simpler proteins, glutenin and gliadin, in the presence of water. It has properties of both elasticity and extensibility, and its unique web-forming characteristics enable it to hold gases produced during fermentation. It is present in small quantities in a number of grains, but only wheat contains enough gluten-forming proteins to make it the preferred grain for making bread flour. [Glossary, p. 240,241]
