Glutenin

From Wikipedia, the free encyclopedia

Glutenin (or glutenine) is a protein best known for its role, along with gliadin, in the creation of gluten with its disulfide inter- and intra-molecule links. It consists of 20% HMW (High-Molecular-Weight) subunits, which are relativy low in sulfur. The other 80% are LMW (Low-Molecular-Weight) subunits and are high in sulfur. It is soluble in diluted acids and bases.

Glutenin is responsible for the firmness of dough in baking bread because it increases the stability through a 3-dimensional network.
