A protide, or amino acid chain, is a molecule made up of a complex chain of amino acids. It is defined as a peptide if it contains a relatively small number of amino acids, and as a protein is this number is high. Certain amino acids are considered as essential because the body cannot produce them itself. They are therefore supplied by food, and all the protides provided this way, of either animal or vegetable origin, play a major role in the body's function, including structuring cells and tissues, constructing muscle fibers, or even involved in the body's energy system.
