Final answer:
Essential amino acids must be provided to the body regularly because they cannot be synthesized by the body and are not stored as carbohydrates or fats are. They are required for protein synthesis, tissue repair, and production of enzymes and hormones.
Step-by-step explanation:
Providing essential amino acids to the body regularly, specifically every 2-3 hours, is crucial because the body lacks the ability to store these vital components like it does with carbohydrates or fats. Essential amino acids are a subset of amino acids that your body cannot synthesize and must be obtained through your diet. These include Methionine, Valine, Lysine, Isoleucine, Leucine, Phenylalanine, Threonine, Tryptophan, and Histidine. Since proteins, which are constructed from amino acids, are continuously being broken down and rebuilt in the body, a consistent supply is necessary to facilitate tissue repair, muscle growth in children, and the production of important molecules such as enzymes and hormones.
