What is Glycine and what Glycine is used for

As an essential trace element in the human body and animals, many people do not know what glycine is. In order to better understand glycine and its uses, this article makes the following summary in detail, hoping to help everyone.

what is glycine used for?

Glycine is a simple amino acid, also known as amino acid, which is involved in the synthesis of purines, porphyrins, creatine and glyoxylic acid, and can be combined with various substances to be excreted in bile or urine. As a nutritional supplement, it is widely used in medicine, food and other fields.

For example, the use of glycine together with glutamic acid and alanine is quite effective in preventing and treating complications of prostatic hypertrophy, urination disturbance, frequent urination, residual urination and other symptoms, and it is also of good quality. According to the preparation process of glycine and the purity of the product, it can be divided into four specifications: food grade, pharmaceutical grade, feed grade and industrial grade.

In terms of medicine, glycine alone can treat nutritional disorders such as severe muscle weakness and promote fat metabolism; as a protein amino acid, it can be used as an important raw material for compound amino acid infusion and oral amino acid preparations; it can also be used as a raw material to further synthesize DL-stupylpropane Amino acid and L-threonine, etc.; as raw materials, it can also be used to synthesize the drug delapril for the treatment of hypertension, and the calcium carbonate preparation for the inhibition of gastric ulcer.

Recently, a brain wave test conducted by Ajinomoto Co., Ltd. in cooperation with Tokyo Jikei Medical University has confirmed that glycine has a quality effect.

In terms of food, currently sodium glutamate (monosodium glutamate) and glycine are the seasonings used in the world. Glycine is a sweet amino acid with a sweetness about 0.8 times that of sucrose. It has a soft sweetness different from sugar, and is used as a flavoring agent in soft drinks and alcohol. Only industrial-grade glycine is clearly not allowed to be added to food.

Glycine Uses


【Use 1】Used as biochemical reagent, used in medicine, feed and food additives, and used as non-toxic decarburizer in nitrogen fertilizer industry

【Use 2】Used in the pharmaceutical industry, biochemical tests and organic synthesis

【Use 3】Glycine is mainly used as a nutritional additive for chicken feed.

【Use 4】Glycine, also known as aminoacetic acid, is used in the production of pesticides to synthesize glycine ethyl ester hydrochloride, the intermediate of pyrethroid insecticides, as well as to synthesize bactericide isobacteron and herbicide solid glyphosate. Phosphine, in addition, it is also used in fertilizers, medicines, food additives, condiments and other industries.

【Use 5】

nutritional supplements. Mainly used for seasoning and so on.

Flavoring and alanine are combined for alcoholic beverages, adding: 0.4% for wine, 0.2% for whisky, and 1.0% for champagne. Others, such as powder soup, add about 2%; distillers grains marinated food 1%. It can be used in seasoning sauces because of its prawn and cuttlefish flavor to a certain extent.

It has a certain inhibitory effect on the reproduction of Bacillus subtilis and Escherichia coli. Therefore, it can be used as a preservative for surimi products, peanut butter, etc., with an addition amount of 1% to 2%.

Buffering Because glycine is a zwitterion with amino and carboxyl groups, it has strong buffering properties. It can buffer the taste of salt and vinegar. The addition amount is 0.3% to 0.7% for salted products and 0.05% to 0.5% for pickled products.

Antioxidant effect (using its metal chelation effect) added to cream, cheese and margarine can prolong the shelf life by 3 to 4 times. To stabilize lard in baked goods, glucose 2, 5% and glycine 0.5% can be added. Add 0.1% to 0.5% to the wheat flour used for quick-cooking noodles, which can also play a seasoning role. In medicine, it is used as an antacid (hyperacidity), a therapeutic agent for muscular dystrophy, an antidote, etc. It is also the raw material for the synthesis of amino acids such as threonine.

According to my country's GB2760-96 regulations, it can be used as spice.

【Use 6】

It is used as a buffer for the preparation of tissue culture medium, for the inspection of copper, gold and silver, and in medicine for the treatment of myasthenia gravis and progressive muscle atrophy, hyperacidity, chronic enteritis, hyperprolinemia in children, etc. disease.

【Use 7】

Treatment of myasthenia gravis and progressive muscle atrophy; treatment of hyperlipidemia, chronic enteritis (often in combination with antacids); combined with aspirin to reduce gastric irritation; treatment of hyperprolinemia in children; as The nitrogen source for generating non-essential amino acids is added to the mixed amino acid injection.

【Use 8】

This product is used as a solvent for removing carbon dioxide in the fertilizer industry. In the pharmaceutical industry, it can be used as an amino acid preparation, a buffer for chlortetracycline, a synthetic raw material for anti-Parkinson's disease drug L-dopa, and an intermediate of ethyl imidazolate, which itself is also an adjuvant therapy. It can treat neurogenic hyperacidity and is also effective in inhibiting hyperacidity in gastric ulcers. In the food industry, it is used as a formula and saccharin debasing agent for synthetic wine, brewing products, meat processing and refreshing beverages. acid, citric acid, etc. In other industries, it can be used as a pH adjuster, added to electroplating solution, or used as a raw material for other amino acids. Used as biochemical reagents and solvents in organic synthesis and biochemistry.

【Use 9】

Complexometric titration indicator, solvent.


1. It is used as a drug for medical microorganism and biochemical amino acid metabolism research;

2. Used as chlortetracycline buffer, anti-Parkinson's disease drug L-dopa, vitamin B6, and synthetic raw materials of amino acids such as threonine;

3. Used as amino acid nutrition infusion;

4. Used as a raw material for cephalosporins; thiamphenicol intermediates; synthetic imidazole acetic acid intermediates, etc.;

5. Used as cosmetic raw material.


It is mainly used as an additive and attractant to increase amino acid in feed for poultry, livestock and poultry, especially pets. Used as a hydrolyzed protein additive, as a synergist for hydrolyzed protein.


For pesticide intermediates, such as as the main raw material of herbicide glyphosate; electroplating solution additives; PH regulators, etc.


1. For peptide synthesis, as amino acid protection monomer;

2. It is used for the preparation of tissue culture medium and the inspection of copper, gold and silver;

3. Because glycine is a zwitterion with amino and carboxyl groups, it has strong buffering properties and is often used as a buffer solution.

What is glycine? The application of glycine is introduced here. From the above, it is known that glycine is widely used in various fields for pharmaceutical industry, biochemical reagents, medicine, feed and food additives, etc.
