Essential amino acids refer to the fact that the human body cannot synthesize or the synthesis speed is far from meeting the needs of the body, and must be supplied by food proteins. These amino acids are called essential amino acids. There are 8 kinds of lysine (Lysine), tryptophan (Tryptophan), phenylalanine (Phenylalanine), methionine (Methionine), threonine (Threonine), isoleucine (Isoleucine), leucine (Leucine), valine (Valine), and another statement lists histidine (Histidine) (which cannot be synthesized in the infant body and needs to be obtained from food) as essential amino acids, a total of 9 kinds.
At the same time, because the source of lysine uptake is relatively small and cannot be synthesized, we call it the first limiting amino acid in the human body.
Promotes brain development, is a component of the liver and gallbladder, can promote fat metabolism, regulate the pineal gland, breast, corpus luteum and ovaries, and prevent cell degeneration.
Lysine is a basic essential amino acid. Since the content of lysine in cereal foods is very low and easily destroyed during processing, it is called the first limiting amino acid.
Lysine can regulate the balance of human metabolism. Lysine provides a structural component for the synthesis of carnitine, which promotes the synthesis of fatty acids in cells. Adding a small amount of lysine to food can stimulate the secretion of pepsin and gastric acid, improve the secretion of gastric juice, and play a role in increasing appetite and promoting the growth and development of young children. Lysine can also improve the absorption of calcium and its accumulation in the body, and accelerate bone growth. Lack of lysine can cause anorexia and nutritional anemia due to insufficient gastric juices, resulting in central nervous system blockage and stunted development.
Lysine can also be used as a diuretic adjuvant in medicine to treat lead poisoning caused by reduced chloride in the blood, and can also generate salts with acidic drugs (such as salicylic acid, etc.) to reduce adverse reactions. Combined with methionine, it can inhibit severe hypertension.
Herpes simplex virus is the cause of cold sores, febrile herpes, and genital herpes, while its related herpes zoster virus is the cause of varicella, herpes zoster, and infectious core solo hyperplasia. Research published in 1979 by Indian Bobo Lilly Research showed that lysine supplementation accelerated recovery from herpes infections and inhibited their recurrence.
Long-term use of lysine can antagonize another amino acid, arginine, which promotes the growth of the herpes virus.
Amino acids are mainly used in medicine to prepare compound amino acid infusions, and are also used as therapeutic drugs and in the synthesis of peptide drugs. There are dozens of amino acids used as drugs, including 20 amino acids that make up proteins and more than 100 amino acids that make up non-proteins.
Compound preparations composed of a variety of amino acids play a very important role in modern intravenous nutrient infusion and "factor diet" therapy, and play a positive role in maintaining the nutrition of critically ill patients and saving their lives. They have become one of the indispensable medical varieties in modern medicine.
Amino acids are the most basic substances that make up biological proteins and are related to life activities. They are the basic units that make up protein molecules in living organisms and are closely related to biological life activities. They have special physiological functions in antibodies and are one of the indispensable nutrients in living organisms.
Foods rich in lysine include fish, such as cuttlefish, octopus, eel, loach, cuttlefish, chicken, seaweed, etc.
Due to the characteristics of lysine, it is easy to decompose lysine when the temperature reaches above 50 degrees, so the way of food intake of lysine is also very limited, so we can better supplement the lysine required by the human body through drugs.
