     It's white monoclinic system or hexagonal system crystals, or white crystalline powder. Odourless, has a special sweetness. Relative density 1.1607. Melting point 248 (decomposition). PK '1 (-cooh) group was 2.34, pK' 2 (N + H3) of 9.60. Solubility: soluble in water, in water at 25 for 25 g / 100 ml; At 50 for 39.1 g / 100 ml; At 75 for 54.4 g / 100 ml; At 100 for 67.2 g / 100 ml. Very difficult to soluble in ethanol, anhydrous ethanol in 100 g of dissolving about 0.06 g. Almost insoluble in acetone and ether. React with hydrochloric acid to generate hydrochloride.

    Glycine has unique sweet taste, can ease acid, alkali, add the bitter taste of saccharine cover food and enhance sweetness. If human take the glycine too much, not only cannot be absorbed by the body to use, and will break the absorption of amino acids for human body balance and interfere with the absorption of other amino acids, bring about nutrient unbalance and the influence is healthy. With glycine containing milk beverage as the main raw material production, it is easy to the normal growth and development of teenagers and children bring adverse impact.

    In the central nervous system, especially in the spine, glycine is an inhibitory neurotransmitter. If the glycine receptors are activated, chloride ion through ion receptors into nerve cells in inhibitory postsynaptic potential. Strychnine is these ion receptors antagonist. In its LD50 in mice index was 0.96 mg/kg body weight, the cause of death is hyperexcitability. In the central nervous system with glycine and glutamic acid is agonist.
