Product Details
DL-Glutamic acid is used ito study its mechanisms of crystal formation and self-assembly on surfaces and copolymer development. It is an alpha-amino acid and a polar amino acid. It contains a 2-carboxyethyl group. It is a conjugate acid of a glutamate(1-). DL-Glutamic acid is the conjugate acid of Glutamic acid, which acts as a fundamental metabolite.
InChI:InChI=1/C5H9NO4/c6-3(5(9)10)1-2-4(7)8/h3H,1-2,6H2,(H,7,8)(H,9,10)
Two strategies involving a chiral additive for the selective crystallization of only d-glutamic acid from a solution of racemic dl-glutamic acid (dl-Glu) are presented. One strategy is based on the addition of sufficient additive (l-arginine or l-phenylalanine with a mole fraction of 40%) and β-d-Glu crystal seeds, the crystal yield reaching 23–25%.
In the case of DL-glutamic acid, molecules are in the zwitterionic form and the crystal … occurring between the molecules of the amino acids themselves and water molecules …
