Protein is an essential nutrient for human body, and amino acid is the basic unit of protein. In other words, all human life activities are closely related to amino acids.

There are eight amino acids that must be consumed through food

There are hundreds of amino acids in nature, but there are only about 20 amino acids that make up the proteins of living organisms. A dozen of them can be synthesized or transformed by the body itself, and eight must be supplied by ingesting food. After eating, the protein in the food will be hydrolyzed under the action of various proteases, thus producing various amino acids. Amino acids are absorbed by the intestinal wall, enter the bloodstream, and recombine to form proteins that the body needs.

Amino acids can be used as drugs to treat diseases

Amino acids in proteins are not only nutrients needed by the body, but also have a certain therapeutic effect on some diseases. For example, glutamic acid, as one of the essential amino acids of the human body, is made into amino acid apis and included in pharmacopoeia. The number and variety of amino acid apis are also increasing.

At present, the clinical applications of amino acid drugs mainly include nutrition supplement, blood ammonia reduction, chronic renal failure and auxiliary treatment of acute and chronic hepatitis. In addition, researchers have also found that many non-protein amino acids have unique biological functions, such as participating in the synthesis of hormones, antibiotics and other substances.

More essential amino acids is not always better

Essential amino acids are also widely used in protein food processing. Some amino acids can be strengthened on food to ensure its nutritional value, but it is necessary to strictly control and master the processing conditions of amino acids, because the human body is not the more essential amino acids the better, but the need for reasonable intake. If the intake of essential amino acids is excessive, a large amount of amino acid and urine black acid will be formed in the human metabolism process, which will seriously affect the intellectual development of children.
