The physiological function of amino acids, the role of amino acids

Amino acids are the basic building blocks for the synthesis of proteins.

And proteins are the basis for the existence of cellular life.

Identification completed.

What are amino acids, amino acids explained, what do amino acids do!

1.The role of amino acid supplements. Because amino acids are needed by the human body, they are also made into health supplements, so that amino acids can also be absorbed by the body in this way like other elements.

In fact, there are many health products about amino acids, here I will introduce the role of amino acid health products with a Merex BCAA nutrition soft capsule, which can form muscles, grow muscles, provide energy, and protect muscles. That is to say, muscles are inseparable from the participation of amino acids, and of course this is just an example of the relationship between amino acids and muscles. 2.

The role of amino acid skin care products. There are also many amino acid skin care products, and what kind of effect can it bring to the body? Take this kind of Anzhi Amino Acid Cleansing Balm as an example, its function is to penetrate into the pores, naturally neutralize excess oil, discharge dirt, protect the health of the skin's sebum film, and at the same time gently and effectively cleanse, more effective skin maintenance, so that the skin is more moisturized and smooth.

Amino acids are added to skin care products to make the effect of skin care more prominent. To sum up, everyone's role in amino acids can bring different effects to your body according to the products you choose. Of course, its role is still very critical, and we must not underestimate the role of amino acids.

Many people will ask, what is the role of amino acids? Actually, amino acids work as follows:

1. It plays a role in nitrogen balance. When the quality and quantity of protein in the daily diet are appropriate, the amount of nitrogen consumed by amino acids is equal to the amount of nitrogen excreted by feces, urine and **, which is called the total nitrogen balance. In fact, there is a balance between the constant synthesis and breakdown of proteins and amino acids.

The daily protein intake of normal people should be kept within a certain range, and when the amount of food consumed is suddenly increased or decreased, the body can still regulate the metabolism of protein and maintain nitrogen balance. If you eat too much protein and exceed the body's ability to regulate, the homeostasis mechanism will be disrupted. If you don't eat protein at all, the tissue protein in the body will still decompose, and the negative nitrogen balance will continue to occur, and if you don't take measures to correct it in time, it will eventually lead to the death of antibodies.

2. Convert into sugar or fat. A ketoacid, produced by the catabolism of amino acids, is metabolized along the metabolic pathways of sugar or lipid with different properties. A Ketoacids can be resynthesized into new amino acids, or converted into sugars or fats, or oxidized into CO2 and H2O into the tricarboxyl cycle, and released energy.

3. Generate one carbon unit. The catabolism of certain amino acids produces groups containing a carbon atom, including methyl group, methylene group, methanyl group, methanyl group, cresol group, and iminomethyl group.

A carbon unit has the following two characteristics:1It cannot exist in a free form in the body of biological ants; 2.

Tetrahydrofolate must be used as a carrier. The amino acids that can form one-carbon units are: serine, tryptophan, histidine, and glycine.

In addition, methionine (methionine) can provide an "active methyl" (one-carbon unit) through S-adenosylmethionine (SAM), so methionine can also produce one-carbon units. The main physiological function of the one-carbon unit is to serve as a raw material for the synthesis of purines and pyrimidines, and is the link between amino acids and nucleotides.

4. Participate in the formation of enzymes, etc. Involved in the formation of enzymes, hormones, and some vitamins. The chemical nature of enzymes is proteins (amino acid molecular makeup), such as amylase, pepsin, cholinesterase, carbonic anhydrase, aminotransferase, etc.

The components of nitrogenous hormones are proteins or their derivatives such as growth hormone, thyroid-stimulating hormone, epinephrine, insulin, intestinal fluid-stimulating hormone, etc. Some vitamins are converted by amino acids or in combination with proteins. Enzymes, hormones, and vitamins play a very important role in regulating physiological functions and catalyzing metabolic processes.

1. Amino acids are mainly used for patients with insufficient protein intake, malabsorption and other amino acids that cannot meet the metabolic needs of the body, and can also be used to improve the nutritional status of patients after surgery.

2. The dosage is 250-500ml intravenous infusion for 1 day, mixed with an appropriate amount of 5%-10% glucose injection, and slowly instilled, and the drip rate should not exceed 20 drops per minute. Amino acids can cause a rash-like allergic reaction, once it occurs, the drug should be stopped, and occasionally nausea, vomiting, chest tightness, palpitations, chills, fever or headache and other adverse reactions may occur.

3. It is strictly forbidden to use it in patients with severe liver and kidney insufficiency, severe uremia and patients with metabolic disorders of amino acids. Patients with severe acidosis and congestive heart failure should use with caution.
