Glycine is a kind of non-essential amino acids for human body. Name abbreviations: Gly is the simplest amino acid series structure, the body is not required an amino acid, both acidic and basic functional groups in the molecule, can be ionized in the water, has a strong hydrophilic, belong to the polar amino acid, soluble in polar solvent, and difficult to soluble in nonpolar solvent , and has high boiling point and melting point, through the regulation of acid and alkaline aqueous solution, can make the glycine presents different molecular forms.
Function And Application:
1. used as medicine in medical microbiology and biochemistry of amino acid metabolism studies;
2. chlortetracycline used as a buffer \anti-Parkinson's disease drugs L- dopa \ vitamin B6 \ and threonine amino acid synthetic materials;
3. used amino acid nutrition infusion;
4. used cephalosporin raw materials; thiamphenicol intermediate; imidazole acetic acid intermediates and so on;
5. used as raw materials for cosmetics.
Nutritional supplements. Mainly used for flavoring and so on. Flavored with alanine together for alcoholic beverages, the addition of: Wine 0.4%, 0.2% whiskey, champagne 1.0%. Others such as powder soup about 2%; 1% lees pickled foods. To a certain extent because it was shrimp, cuttlefish flavor, it can be used in sauces. Bacillus subtilis and E. coli breeding a certain extent. It can be used surimi products, peanut butter and other preservatives added amount of 1% to 2%. Because glycine buffer having amino and carboxyl zwitterionic, it has a strong cushioning properties. Salt and vinegar to taste sense can play a buffer role. Salted product dosage of 0.3% to 0.7%, acid stain product from 0.05% to 0.5%. Antioxidant (with its metal chelation) add in butter, cheese, margarine extend the shelf life of 3 to 4 times. To make baked in lard stable, add glucose 2.5% and 0.5% glycine. Adding 0.1% to 0.5% rate with wheat flour noodles, and can play a role in flavor. Medicine for antacids (hyperacidity), muscle nutritional disorder therapeutic agent antidotes. Synthetic material is also threonine amino acids.
