Solid glycine is a white to off white crystalline powder, odorless, and non-toxic. Easy to dissolve in water, almost insoluble in ethanol or ether. Used in the pharmaceutical industry, biochemical testing, and organic synthesis, it is the simplest amino acid in the amino acid series and is not essential for the human body. It has both acidic and basic functional groups in the molecule, can be ionized in water, and has strong hydrophilicity. However, it belongs to non-polar amino acids and is soluble in polar solvents but difficult to dissolve in non-polar solvents. It also has a high boiling point and melting point. By adjusting the acidity and alkalinity of aqueous solutions, glycine can present different molecular forms
