What is Glycine? 

Glycine is the simplest (and the only achiral) proteinogenic amino acid, with a hydrogen atom as its side chain. It has a role as a nutraceutical, a hepatoprotective agent, an EC (glycine hydroxymethyltransferase) inhibitor, a NMDA receptor agonist, a micronutrient, a fundamental metabolite and a neurotransmitter. It is an alpha-amino acid, a serine family amino acid and a proteinogenic amino acid. It is a conjugate base of a glycinium. It is a conjugate acid of a glycinate. It is a tautomer of a glycine zwitterion.

Usage And Synthesis

Chemical Properties: Glycine occurs as a white, odorless, crystalline powder, and has a sweet taste.  

Glycine Uses:

  1. Used as a biochemical reagent, used in medicine, feed and food additives, and used as a non-toxic decarbonizer in the nitrogen fertilizer industry.

  2. Used in the pharmaceutical industry, biochemical tests and organic synthesis.

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

  4. Glycine, also known as aminoacetic acid, is used in the production of pesticides to synthesize pyrethroid insecticides as an intermediate glycine ethyl ester hydrochloride, and can also be used to synthesize fungicide iprodione and herbicide solid glyphosate. In addition, , It is also used in fertilizer, medicine, food additives, condiment and other industries.

  5. Nutritional supplements. Mainly used for seasoning and so on. Antioxidant effect added to cream, cheese, margarine can prolong the shelf life by 3 to 4 times. In order to stabilize the lard in the baked goods, 2.5% glucose and 0.5% glycine can be added. Add 0.1% to 0.5% of wheat flour for instant noodles, and it can also be used for seasoning. Used in medicine as antacid (hyperacidity), muscular malnutrition treatment agent, antidote, etc. It is also a synthetic raw material for amino acids such as threonine.

  6. Used as a buffer, used in the preparation of tissue culture medium, copper, gold and silver testing, and used in medicine to treat the diseases of myasthenia gravis and progressive muscle atrophy, hyperacidity, chronic enteritis, hyperprolineemia from children, etc...
