Glycine is a non essential amino acid with the chemical formula C2H5NO2. Glycine is a constituent amino acid of endogenous antioxidant glutathione, which is often supplemented externally during severe stress in the body and is sometimes referred to as a semi essential amino acid. Glycine is the simplest amino acid.
Food
1. Used as a biochemical reagent, it can also be used as a pharmaceutical, feed, and food additive. In the nitrogen fertilizer industry, it is used as a non-toxic decarbonizer;
2. Used as a nutritional supplement, mainly for seasoning and other purposes;
3. It has a certain inhibitory effect on the reproduction of Bacillus subtilis and Escherichia coli, so it can be used as a preservative for fish mince products, peanut butter, etc., with an added amount of 1% to 2%;
4. It has antioxidant properties (utilizing its metal chelation effect) and can be added to cream, cheese, and margarine to extend the shelf life by 3-4 times;
5. To stabilize lard in baked goods, 2.5% glucose and 0.5% glycine can be added;
6. Adding 0.1% to 0.5% wheat flour for quick cooking noodles can also serve as a seasoning;
7. It can provide a buffering effect on the taste of salt and vinegar, with an added amount of 0.3% to 0.7% for salt pickled products and 0.05% to 0.5% for acid pickled products;
8. According to the regulations of GB2760-96 in China, it can be used as a spice.
Medicine
1. Used as a medication for medical microbiology and biochemical amino acid metabolism research;
2.Used as a buffer for streptomycin, vitamin B6 for anti Parkinson's disease drugs, and synthetic raw materials for amino acids such as methionine;
3. Treat myasthenia gravis and progressive muscle atrophy;
4. Treatment of excessive gastric ester and chronic enteritis (often combined with antacids);
5. Combined with aspirin, it can reduce its irritation to the stomach;
6. Treatment of hyperprolactinemia in children;
7. As a nitrogen source for generating non essential amino acids, it is added to the mixed amino acid injection solution.
Agriculture
1. Mainly used as an additive and attractant to increase amino acids in feed for poultry, livestock, especially pets. Used as an additive for hydrolyzed protein and as an enhancer for hydrolyzed protein;
2. Glycine ethyl ester hydrochloride, an intermediate used in pesticide production to synthesize pyrethroid insecticides, can also be used to synthesize fungicides such as ipratropium and herbicides such as solid glyphosate.
Industry
1. Used as an additive in electroplating solution;
2. Used in the pharmaceutical industry, biochemical testing, and organic synthesis;
3. Used as a raw material for cephalosporins, intermediate for methicillin, intermediate for synthesizing imidazole acetic acid, etc;
4. Used as a cosmetic ingredient.
reagent
1. Used for peptide synthesis and as an amino acid protecting monomer;
2. Used for the preparation of tissue culture media and the testing of copper, gold, and silver;
3. Due to glycine being a zwitterionic compound with both amino and carboxyl groups, it has strong buffering properties and is commonly used in the preparation of buffer solutions;
4. Used as a complexometric titration indicator and solvent.
