The solid glycine is white monoclinic or hexagonal crystal or white crystalline powder, odorless and non-toxic [2]; it is soluble in water and almost insoluble in ethanol or ether. Boiling point: 233 ℃, melting point: 240 ℃ (Dec.) (lit.), used in pharmaceutical industry, biochemical test and organic synthesis, is a kind of amino acid with the simplest structure and unnecessary for human body in amino acid series. It has both acidic and basic functional groups in the molecule, can be ionized in water, and has strong hydrophilicity, but it belongs to non-polar amino acid, soluble in polar solvent, but difficult to dissolve in non-polar solvent [3] Glycine has higher boiling point and melting point. Glycine can be changed into different molecular forms by adjusting the acidity and basicity of aqueous solution |
