Glycine, also known as aminoacetic acid, is a non essential amino acid with the chemical formula C2H5NO2. Glycine is a constituent amino acid of endogenous antioxidant glutathione, which is often supplemented externally during severe stress in the body and is sometimes referred to as a semi essential amino acid. Glycine is the simplest amino acid.
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, soluble in polar solvents but difficult to dissolve in non-polar solvents, and has a high boiling point and melting point. By adjusting the acidity and alkalinity of aqueous solutions, glycine can present different molecular forms.
1. Used as a medication for medical microbiology and biochemical amino acid metabolism research;
2. Used as a buffer for streptomycin, L-dopa for anti Parkinson's disease drugs, vitamin B6, and synthetic raw materials for amino acids such as methionine;
3. Treat myasthenia gravis and progressive muscle atrophy;
4. Treatment of excessive gastric ester and chronic enteritis (often combined with antacids);
5. Combined with aspirin, it can reduce its irritation to the stomach;
6. Treatment of hyperprolactinemia in children;
7. As a nitrogen source for generating non essential amino acids, it is added to the mixed amino acid injection solution.
