There are 10 essential amino acids for infants and young children, including lysine, tryptophan, phenylalanine and methionine.
Essential amino acids are those amino acids that cannot be synthesized by the human body or the synthesis rate is far from being adapted to the needs of the organism, and must be supplied by food proteins, and these amino acids are called essential amino acids.
They are lysine (Lysine), tryptophan (Tryptophane), phenylalanine (Phenylalanine), methionine (Methionine), threonine (Threonine), isoleucine (Isoleucine), leucine (Leucine), valine (Valine) eight, another Hlstidine and Argnine are also listed as essential amino acids, making a total of 10.
Essential amino acids must be obtained directly from food, otherwise the nitrogen balance of the body cannot be maintained and health is affected. The nutritional value of protein in food depends mainly on the type, content and proportion of the essential amino acids contained in the food and whether they are similar to those required by the human body. Therefore, a mixture of animal and plant proteins and a mixture of different plant proteins can improve the nutritional value of plant-based proteins.
