    Children who have learned biology know that amino acids have an important relationship with people's physical health.
    it is the most basic substance that constitutes the protein of living organisms and is related to life activity, it is one of the most basic substances that make up human body, and it is the basis of life metabolism.
    so today's article will focus on introducing you to what amino acids are? How many of them are there and what are its effects and efficacy? Next, let the small editor to give you the relevant introduction.
    there are numerous amino acids in theory, as long as there is an amino and a carbide-based carbon and no effective peptide bond.
    only 20 of these amino acids are used by proteins formed by living organisms.
    only these 20 natural amino acids can strictly adhere to the structural generality, they are: 1. Tryptophan 2. Lysine 3. Phenylalanine 4. Methionine 5. Sousse 6. Proline 7. Liangine 8. Isolyluminine 9. Cysteine 10. Serine 11. Glycine 12. Tyrosine 13. Winter sine 14. Winteramide 15. Glutamate 16. Glutamine 17.Alanine 18. Arginine 19. The first 8 types of histamine 20. Proline are called essential amino acids that cannot be synthesized in the human body and need to be obtained from food. The amount of synthesized arginine and histamine in the human body generally does not meet its own requirements, or must be further obtained from food, these two amino acids we call semi-essential amino acids. the role of
    amino acids 1, protein digestion and absorption in the body is done through amino acids: as the body's first nutrient element of protein, its role in food nutrition is obvious, but it can not be directly used in the human body, but by becoming amino acid molecules after being used.
    2, nitrogen balance: When the quality and amount of protein in the daily diet is appropriate, the amount of nitrogen ingested is equal by the amount of nitrogen emitted by manure, urine and skin, called the total balance of nitrogen.
    is actually a balance between the constant synthesis and decomposition of proteins and amino acids.
    normal people eat protein should be kept within a certain range, suddenly increase or decrease the amount of food intake, the body can still regulate the amount of protein metabolism to maintain nitrogen balance.
    eat too much protein, beyond the body's ability to regulate, the balance mechanism will be destroyed.
    do not eat protein at all, the body tissue protein is still broken down, the continuous appearance of negative nitrogen balance, if not timely measures to correct, will eventually lead to antibody death.
    3, converted to sugar or fat: amino acids break down metabolism produced by a-ketoacid, along with different characteristics, follow the metabolic pathways of sugar or fat.
    a-ketoacids can be synthesized into new amino acids, or converted into sugar or fat, or into the triamcinolone cycle oxidized into CO2 and H2O, and released energy.
    4, participating in the composition of enzymes, hormones, part of vitamins: the chemical nature of enzymes is protein (amino acid molecular composition), such as amylase, gastric protease, choline lipase, carbonatease, transaminase and so on.
    nitrogen-containing hormones are proteins or their derivatives, such as growth hormone, thyroid-promoting hormone, epinephrine, insulin, enterolytic fluid hormone, etc.
    some vitamins are transformed by amino acids or bind to proteins.
    , hormones and vitamins play an important role in regulating physiological function and catalytic metabolism.
    5, the amount of essential amino acids in the human body: the amount of essential amino acids in adults is about 20% of the protein ,—— 37%.
    effect of amino acids 1, long-term life if the body lacks more protein decomposition and synthesis slows down.
    , therefore, older people need more protein than young adults, and the demand for methionine and lysine is higher than that of young adults.
    people over 60 years of age should consume about 70 grams of protein per day, and the protein is required to contain a full range of essential amino acids and appropriate ratio, so that high-quality protein, longevity.
    2, amino acids are mainly used in medicine to prepare compound amino acid infusions, but also used as therapeutic drugs and for the synthesis of peptide drugs.
    there are more than a hundred amino acids currently 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 nutrition infusions and "factor diet" therapy, which play a positive role in maintaining the nutrition of critically ill patients and saving patients' lives, and become one of the indispensable medical varieties in modern medical treatment.
    Glutamate, arginine, tianmendonine, cysteine, L-doba and other amino acids act alone to treat some diseases, mainly used in the treatment of liver disease, digestive diseases, encephalopathy, cardiovascular disease, respiratory diseases and used to improve muscle vitality, pediatric nutrition and detoxification.
    in addition, amino acid derivatives have been shown to be promising in cancer treatment.
    Food nutrition human in order to survive the necessary intake of food, in order to maintain the normal antibody physiological, biochemical, immune function, as well as growth and development, metabolism and other life activities, food in the body after digestion, absorption, metabolism, promote antibody growth and development, nootropic health, anti-aging disease, life-extending comprehensive process called nutrition.
    active ingredient in food is called nutrients.
    proteins, lipids, carbohydrates, inorganic salts (i.e. minerals, containing constants and trace elements), vitamins, water and food fiber, which are the most basic substances that make up the human body, are also nutrients needed by the human body.
    they have their own unique nutritional functions in the body, but are closely linked in the metabolic process to participate in, promote and regulate life activities.
    the body through food contact with the outside world, maintain a relatively constant internal environment, and complete the unity and balance of the internal and external environment.
