Essential amino acids are those that the human body does not produce in sufficient quantities to meet its needs and must be supplied with food. They are also called essential. Understanding them was an important stage in the study of proteins: not only the total mass of the protein is important, but also its amino acid composition.
Characteristics and context
This group in adults includes, among others, lysine, leucine and tryptophan. Different protein foods provide them in different proportions, and diversifying your food helps combine these sources. The abbreviation EAA used in the trade comes from essential amino acids. A preparation containing one amino acid is not automatically a full set of EAAs. It is worth checking the exact names and quantities on the label, instead of identifying each mixture with a complete protein.
Meaning and application
Food proteins differ in the proportions of amino acids, so their quantity and quality of amino acids are not exactly the same issue. This does not mean a simple division of all products into good and bad. Diverse sources can complement each other in the daily menu. Assessment of the entire diet is broader than checking one ingredient. The concept of necessity also refers to the needs of the body, and not to the marketing value or uniqueness of a given powder.
In practice
The abbreviation BCAA refers only to three branched chain amino acids and is not synonymous with the full set of EAAs. In turn, the addition of one amino acid to a multi-ingredient capsule does not make the preparation a substitute for all protein sources. The exact amounts per serving and a full list of ingredients are useful on the label. The mass of the entire mixture should not be equated with the mass of each amino acid separately. This distinction allows you to read offers without confusing group names with actual product content.
