What are the nine essential amino acids? What are their functions and what foods contain them?
[Edit this paragraph] Definition of essential amino acids Essential amino acids: Amino acids that are necessary for human body (or other vertebrates) but cannot be synthesized in vivo and must be supplemented from food are called essential amino acids.

For adults, there are eight kinds of amino acids, including lysine, methionine, leucine, isoleucine, threonine, valine, tryptophan and phenylalanine. Histidine is also an essential amino acid for infants. [Edit this paragraph] There are eight essential amino acids for human body: lysine, tryptophan, phenylalanine, methionine, threonine, isoleucine, leucine and valine. Histidine and arginine are also essential amino acids for infants. If the above amino acids are often lacking in the diet, it will affect health.

(1) Lysine: promotes brain development, is a component of liver and gallbladder, can promote fat metabolism, regulate pineal gland, breast, corpus luteum and ovary, and prevent cell degeneration;

(2) Tryptophan: promoting the production of gastric juice and pancreatic juice;

(3) phenylalanine: involved in eliminating the loss of kidney and bladder function;

(4) methionine (also known as methionine); Participate in the composition of hemoglobin, tissue and serum, and have the function of promoting spleen, pancreas and lymph;

(5) Threonine has the function of transforming some amino acids to achieve balance;

(6) Isoleucine: involved in the regulation and metabolism of thymus, spleen and submandibular gland; The commander-in-chief of submandibular gland acts on thyroid gland and gonad;

(7) Leucine: Isoleucine with balanced action;

(8) Valine: It acts on corpus luteum, mammary gland and ovary.

(9)Hlstidine: It acts on the regulation of metabolism;

(X) Arginine: Arginine is an essential amino acid in the growth period of young children.

Memory method: Party A brings (Valeriana officinalis) a book (benzene) with bright colors (Soviet Union).

This memory: the color of the egg is bright (especially bright), and the book is borrowed (borrowed) (Sue).

What the teacher taught us: A, B and C come (borrow) blue (bright) books (Su).

There is also a formula: bring one (different) two (bright) (benzene) single (egg) color books (Su) to (Lai)-bring one or two monochrome books.

Nanda Edition: Idiot Jun came to the dormitory to hang sandals.

Phenyl-methionine-essence (essential for babies)-Lysol-color-brightness-extraordinary brightness -Valle [edit this paragraph] The main functions of essential amino acids are: necessary for body growth, maintenance and maintenance.

Lack of symptoms:

(1) lacks vitality and energy.

2 premature aging.

(3) The wound healing performance is poor.

④ Children are stunted.

One. lysine

1 is involved in the formation of connective tissue and microvessel epithelial cell stroma, and maintains normal permeability.

2, can increase appetite, promote the secretion of pepsin, enhance immunity, improve growth retardation, prevent tooth decay, and promote children's growth.

3. Improve calcium absorption and promote bone growth.

4. If it is lacking, it will reduce people's sensitivity, and women will stop menstruation and have symptoms such as anemia, dizziness, dizziness and nausea.

Two. Tryptophan (try)

1, promoting the synthesis of hemoglobin.

2, prevention and treatment of furuncle.

3. Promote growth and increase appetite.

4. The sweetness is 35 times that of granulated sugar, and the prepared low-pond food is more suitable for diabetics and obese patients.

Three. Phenylalanine (PHE)

It is converted into tyrosine in the body and promotes the synthesis of thyroxine, kidney and adrenaline.

Four. methionine

1, which participates in the synthesis of choline, has the function of removing fat and preventing arteriosclerosis and hyperlipidemia.

2. It can improve muscle vitality.

3. Promote the synthesis of skin protein and insulin.

Verb (abbreviation of verb) THReonine (thr)

The human body is necessary, and when it is lacking, it will make people thin and even die.

6. Isoleucine (ILE)

1, which can maintain body balance and treat mental disorders.

2. It can stimulate appetite and fight anemia.

3. If it is lacking, there will be symptoms such as physical exhaustion and coma.

Seven. Low enriched uranium

1, lowering the blood sugar level is effective in treating dizziness.

2. Promote the healing of skin, wounds and bones.

If it is deficient, it will stop growing and lose weight.

Eight. valine

1, promoting the normal function of the nervous system.

2. Without it, the tactile sensitivity will be particularly improved, and muscle ataxia will be out of balance.

3. It can be used as a medicine for treating hepatic coma.

Nine. histidine

1, which participates in the synthesis of hemoglobin and promotes blood production.

2. Produce histidine, promote blood vessel dilation and increase blood vessel wall permeability.

3, it has special effects on treating stomach diseases and duodenum.

4, promote gland secretion, and have an effect on allergic diseases.

5, can treat peptic ulcer, dysplasia and other symptoms.

6. It is effective in treating cardiac insufficiency, angina pectoris, lowering blood pressure, asthma and rheumatoid arthritis. [Edit this paragraph] Essential amino acids for animals The types of essential amino acids required by various animals are roughly the same, but there are some differences due to their different genetic characteristics.

At present, there are 13 kinds of essential amino acids for chickens, namely arginine, lysine, histidine, methionine, arginine, tryptophan, phenylalanine, tyrosine, leucine, isoleucine, threonine, glycine and methionine. If the chicken's diet lacks some essential amino acids or the content of essential amino acids is insufficient, it will affect the synthesis of protein in the chicken, the growth and development of the chicken will stop, the weight will be reduced, the physique will be weak, and the laying rate will drop.

Essential amino acids are sometimes transformed in a direction unfavorable to human beings.

For example, in the case of phenylketonuria (a monogenic genetic disease), phenylalanine will be converted into phenylpyruvic acid essential amino acid injection, also known as essential amino acid injection, and renal amino acid infusion.

Indications are mainly suitable for chronic renal failure, especially the negative nitrogen balance that can not be corrected by low-protein diet, and can also be used to improve the nutritional status of patients with acute renal failure and dialysis patients.

Dosage and Usage: Intravenous drip: The usual dosage is 250 ml per day, and then mixed with glucose solution and slowly dripped (per minute 15 drops).

Matters needing attention

Dropping too fast can cause nausea, vomiting, palpitation, fever and so on. , especially suitable for the elderly and critically ill patients. Some patients may have hyperchloremia, accompanied by decreased carbon dioxide binding capacity, which can be corrected by appropriate amount of sodium bicarbonate. Liver failure, hyperchloremia, severe dehydration and insufficient blood volume are not suitable for use. Pay attention to the changes of blood sugar, serum protein, electrolyte and liver and kidney function. Patients with hepatic insufficiency, hyperchloremia and severe dehydration are prohibited.

Specification injection: 250ml.

Character injection.

Intake method of amino acids:

It mainly balances the human body through food or foreign sources;

One can be obtained by the human body through sunlight;

Through the body's own synthesis.

Rosa roxburghii is rich in seven essential amino acids, which can effectively supplement human needs and make people healthy. SOD soft gold on the market now contains more than a dozen amino acids and a lot of mineral elements.

Definition of nutrition

Essential amino acids refer to amino acids that the human body can't synthesize or the speed of synthesis can't meet the needs of the body, and must be obtained directly from food. Protein consists of 20 kinds of amino acids, 9 of which are essential amino acids, namely isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, valine and histidine.
