Our organism transforms the starch into sugar, that is, into energy. Starch absorbs a great quantity of water, while gliadin and glutenin do not absorb any. If we can compare the act of mixing dough to that of building a wall, we could say that the starch granules are like the bricks, while the gluten is the mortar which incorporates them and keeps them firmly in place. Their main role is to act as an energy reserve. Most of this fatty tissue is found directly under the skin and acts to isolate the body and maintain internal temperature constant.
Protein There are many types of protein.
Just as we can combine the 26 letters of the alphabet to form thousands of words with different meanings, differentiated by their length and the order of the letters, so the twenty amino acids, the building blocks of protein, can be combined in different ways to produce thousands of different chains, each one of which has a very specific task. As organisms grow, day in and day out, new proteins must be built in order to build new tissues. They are the only nutrients which contain nitrogen, and since our cells are not capable of storing this element, it is necessary to consume a certain amount of protein on a daily basis.
