                                While many ask, 'What are the three types of gluten?', the simple answer is there is no such classification; gluten isn't a single substance but a complex mixture of storage proteins. Specifically, in wheat, the two major protein groups are gliadins and glutenins, which combine to form the unique viscoelastic network known as gluten when mixed with water.
