Glycine is amino acid series of 20 members of one of the most simple in structure, also known as amino acetic acid, an amino acid that's not necessary for the human body, both acidic and basic functional groups in the molecule, for strong Chemicalbook electrolytes in aqueous solution, in strong polar solvent solubility is bigger, basic not soluble in nonpolar solvents, 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.

1.Treatment of myasthenia gravis and progressive muscle atrophy;
2.Treatment of gastroparesis and chronic enteritis (often used in combination with antacids);
3.When used in combination with aspirin, it reduces irritation to the stomach;
4.Treatment of hyperprolinemia in children;
5.As a nitrogen source for the production of non-essential amino acids, it was added into the mixed amino acid injection.
1.When Glycine is used as a kind of Nutritional supplement, it Mainly used for seasoning and other aspects.
Flavoring and alanine are used in alcoholic drinks. The added amount is 0.4% for wine, 0.2% for whiskey and 1.0% for champagne.Others such as powder soup add about 2%;1% food cured with distiller's grains.Because it can be a certain degree of shrimp, cuttlefish flavor, can be used for sauces.
2.It can inhibit the reproduction of subtilis and Escherichia coli.Therefore, it can be used as a preservative for surimi products, peanut butter, etc., with an added amount of 1% ~ 2%.Because glycine is amphoteric ion with amino and carboxyl groups, it has strong buffering effect.Chemicalbook buffers the flavor of salt and vinegar.The added amount was 0.3% ~ 0.7% for salt and 0.05% ~ 0.5% for acid.
3.The antioxidant effect (using its metal chelating agent) added to butter, cheese and margarine can prolong the storage life by 3 ~ 4 times.To stabilize lard in baked goods, glucose 2.5% and glycine 0.5% are added.Add 0.1% ~ 0.5% into the wheat flour used for quick-cooking noodles, and it can also play the role of seasoning.
4.Medically used as acid production agent (hyperacidity), muscular dystrophy therapeutic agent, antidote and so on.It is also the raw material for synthesis of amino acids such as threonine.
