L-Glycine Introduction: Glycine (abbreviated as Gly) is a non essential amino acid with the chemical formula C2H5NO2. Glycine is an amino acid that is a component of endogenous antioxidant reduced glutathione. When the body experiences severe stress, it is often supplemented externally, sometimes also known as a semi essential amino acid.
Solid glycine is a white to grayish white crystalline powder, odorless, and non-toxic. Easy to dissolve in water, almost insoluble in ethanol or ether. Used in the pharmaceutical industry, biochemical experiments, 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 alkaline functional groups in its molecules, and can ionize in water with strong hydrophilicity. However, it is a non-polar amino acid that is soluble in polar solvents but difficult to dissolve in non-polar solvents, and has a high boiling and melting point. By adjusting the acidity and alkalinity of the aqueous solution, glycine can present different molecular forms.
