Glutenin

Glutenin (or glutenine) is the glutelin

Glutelin

Glutelins are soluble in dilute acids or bases, detergents, chaotropic or reducing agents. They are generally prolamin-like proteins in certain grass seeds. glutenin is the most common glutelin as it is found in wheat and is responsible from some of the refined baking properties in bread wheat...

is a protein

Protein

Proteins are organic compounds made of amino acids arranged in a linear chain and folded into a globular form. The amino acids in a polymer chain are joined together by the peptide bonds between the carboxyl and amino groups of adjacent amino acid residues...

 best known for its role, along with gliadin

Gliadin

Gliadin is a glycoprotein present in wheat and several other cereals within the grass genus Triticum. Gliadins are prolamins and are separated on the basis of electrophoretic mobility and isoelectric focusing.- Types :...

, in the creation of gluten

Gluten

Gluten is a composite of the proteins gliadin and glutenin. These exist, conjoined with starch, in the endosperms of some grass-related grains, notably wheat, rye, and barley. Gliadin and glutenin comprise about 80% of the protein contained in wheat seed. Being insoluble in water, they can be...

Disulfide

In chemistry, a disulfide usually refers to the structural unit composed of a linked pair of sulfur atoms. Disulfide usually refer to a chemical compound that contains a disulfide bond, such as diphenyl disulfide, C₆H₅S-SC₆H₅.-Inorganic vs. organic...

Molecule

A molecule is defined as an electrically neutral group of at least two atoms in a definite arrangement held together by very strong chemical bonds. Molecules are distinguished from polyatomic ions in this strict sense...

 links. It consists of 20% HMW (High-Molecular-Weight) subunits, which are relatively low in sulfur. The other 80% are LMW (Low-Molecular-Weight) subunits and are high in sulfur. It is soluble in diluted

Dilution

Dilution may refer to:* Reducing the concentration of a chemical* Serial dilution, a common way of going about this reduction of concentration.* Homeopathic dilution* Dilution , an equation to calculate the rate a gas dilutes...

Acid

An acid is traditionally considered any chemical compound that, when dissolved in water, gives a solution with a hydrogen ion activity greater than in pure water, i.e. a pH less than 7.0...

s and bases

Base (chemistry)

In chemistry, a base is most commonly thought of as an aqueous substance that can accept hydrogen ions. Bases are also the oxides or hydroxides of metals. A soluble base is also often referred to as an alkali if hydroxide ions are involved. This refers to the Brønsted-Lowry theory of acids and bases...

.

Glutenin is responsible for the firmness of dough in baking bread because it increases the stability through a 3-dimensional network that forms when sulfur cross-linkages

Disulfide bond

In chemistry, a disulfide bond is a covalent bond, usually derived by the coupling of two thiol groups. The linkage is also called an SS-bond or disulfide bridge. The overall connectivity is therefore C-S-S-C. The terminology is widely used in biochemistry...
