Metabolite Identification
Common NameGlycine
DescriptionGlycine, also known as Gly or aminoessigsaeure, belongs to the class of organic compounds known as alpha amino acids. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Glycine exists as a solid, possibly soluble (in water), and a very strong basic compound (based on its pKa) molecule. Glycine exists in all living species, ranging from bacteria to humans. Glycine is a potentially toxic compound. Glycine has been found to be associated with several diseases known as crohn's disease, leukemia, phosphoserine aminotransferase deficiency, and hyperglycinemia, lactic acidosis, and seizures; also glycine has been linked to the inborn metabolic disorders including n-acetylglutamate synthetase deficiency.
