For this reason, the solubility of glycine in water, water–ethanol mixtures, and ethanol was remeasured. Is glycine a structure? Glycine (symbol Gly or G; ) is an amino acid that has a single hydrogen atom as its side chain. Its acid–base properties are most important. In aqueous solution, glycine is amphoteric: below pH = 2.4, it converts to the ammonium cation called glycinium. Above about 9.6, it converts to glycinate. Glycine functions as a bidentate ligand for many metal ions, forming amino acid complexes. A typical complex is Cu(glycinate)2, i.e. Cu(H2NCH2CO2)2, which …
