Glycine CAS 56-40-6

Glycine is one of the 20 members of the amino acid series with the simplest structure, also known as aminoacetic acid, a non-essential amino acid for the human body, in the molecule with both acidic and alkaline functional groups, in aqueous solution as a strong electrolyte, in the strong polarity of the solvent solubility is greater, basically insoluble in non-polar solvents, and has a high boiling and melting points, through the regulation of the acidity and alkalinity of the aqueous solution can be made to make Glycine show different by adjusting the acidity and base of the aqueous solution, glycine can be made to show different molecular forms. The side bond of glycine is a hydrogen atom. Due to the fact that there is also a hydrogen atom at its α-carbon, glycine is not cyclically isomorphic. Because glycine's side bond is so small, it can occupy spaces that other amino acids cannot, for example as an amino acid within the collagen helix. It is a white crystal or light yellow crystalline Chemicalbook powder at room temperature. It has a unique sweet flavour, which can moderate acidic and alkaline flavours, mask the bitterness of added saccharin in food and enhance sweetness. If the human body intakes too much glycine, not only can't be absorbed and utilised by the human body, but also it will break the balance of amino acid absorption in the human body and affect the absorption of other amino acids, leading to nutritional imbalance and affecting health. Milk beverages produced with glycine as the main raw material can easily affect the normal growth and development of adolescents and children. Density 1.1607, melting point 232~236°C (decomposition). Soluble in water, insoluble in ethanol and ether. It can act with hydrochloric acid to form hydrochloride. Exists in the sinews of dry low-grade carriers. It can be made by the action of monochloroacetic acid and ammonium hydroxide, or hydrolysed and refined by gelatin.

1. Performance and use:

White monoclinic or hexagonal crystal system, or white crystalline powder. Odourless, with special sweet taste. Easily soluble in water, solubility in water: 25g/100ml at 25°C; 39.1g/100mChemicalbookl at 50°C; 54.4g/100ml at 75°C; 67.2g/100ml at 100°C. Extremely difficult to dissolve in ethanol, in 100g anhydrous ethanol dissolved in about 0.06g. Almost insoluble in acetone and ether.

Used in pharmaceutical industry, biochemical test and organic synthesis.

Used as buffer, used in the preparation of tissue culture medium, the test of copper, gold and silver, used in medicine for the treatment of myasthenia gravis and progressive muscular dystrophy, hyperacidity, chronic enteritis, hyperprolinemia in children and other diseases.

It is used in the treatment of myasthenia gravis and progressive muscular atrophy; in the treatment of hypergastritis, chronic enteritis (often combined with antacids); in combination with aspirin to reduce its gastric irritation; in the treatment of hyperprolinemia in children; as a source of nitrogen for the production of non-essential amino acids, it is added to mixed amino acid injections.

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